Type 2 Transient Surge Protector Acti9 iPFK65 65KA 340V 3P+N

The Schneider Electric Acti9 iPF K 65 A9L15586 surge protection device is a Type 2 SPD in 3P+N configuration, designed to limit transient overvoltages that can enter an electrical installation due to atmospheric phenomena or switching operations on the network. It offers a maximum discharge current Imax of 65 kA, a nominal discharge current In of 20 kA, and a protection level Up below 1.5 kV. It is intended for three-phase 230/400 V AC installations with TT and TN-S earthing systems.

Reference A9L15586 belongs to Schneider Electric's Acti9 iPF K range and combines MOV + GDT technologies to provide protection between phases, neutral, and earth. Its modular DIN rail design occupies 4 modules of 18 mm and is especially suitable for distribution boards where a high discharge capacity against transient overvoltages is required.

Type 2 surge protection device

The Schneider Electric A9L15586 is classified as a Type 2 SPD according to IEC 61643-11:2011. This type of device is intended to limit transient overvoltages reaching an installation and reduce the residual voltage before it can affect connected equipment.

Schneider Electric identifies it as a solution for secondary load protection, and it can be used in cascade with other surge protectors installed upstream when the installation protection design requires it.

3P+N configuration for three-phase installations

The Acti9 iPF K 65 A9L15586 has a 3P+N configuration, suitable for three-phase installations with neutral.

• Configuration: 3P+N.
• Rated operating voltage Ue: 230/400 V AC ±10%.
• Frequency: 50/60 Hz.
• Earthing systems: TT and TN-S.

Compatibility with the earthing system must always be checked before selecting a surge protector, as it determines how the protection elements are connected between phase, neutral, and earth.

Imax of 65 kA

The 65 kA value included in the product name corresponds to the maximum discharge current Imax with an 8/20 µs waveform.

• Imax L-PE: 65 kA.
• Imax N-PE: 65 kA.
• Imax L-N: 65 kA.

Imax represents the maximum impulse current that the SPD can discharge under the standardized test conditions of a Type 2 device.

Nominal discharge current In of 20 kA

The nominal discharge current In of the A9L15586 is 20 kA with an 8/20 µs waveform.

• In L-PE: 20 kA.
• In N-PE: 20 kA.
• In L-N: 20 kA.

Therefore, the two parameters must be clearly distinguished:

• In = 20 kA: nominal discharge current.
• Imax = 65 kA: maximum discharge current.

Uc of 340 V between phase and neutral

The maximum continuous operating voltage Uc depends on the connection mode:

• Uc L-N: 340 V AC.
• Uc N-PE: 260 V AC.

For this reason, the 340 V indicated in the commercial name corresponds specifically to the maximum permissible continuous voltage between phase and neutral.

Protection level Up below 1.5 kV

The voltage protection level Up specified by Schneider Electric is below 1.5 kV in both differential mode and between neutral and earth:

• Up L-N: <1.5 kV.
• Up N-PE: <1.5 kV.

This parameter expresses the maximum residual voltage that appears across the protector during standardized discharge conditions.

MOV + GDT technology

The A9L15586 combines two protection technologies:

• MOV: metal oxide varistors.
• GDT: gas discharge tube.

This architecture is adapted to the 3P+N configuration and to the TT and TN-S networks covered by Schneider Electric.

Short-circuit current Isccr of 25 kA

The device has a rated short-circuit current Isccr of 25 kA within the coordination conditions established by the manufacturer.

This value does not mean that the SPD replaces a circuit breaker or fuse. The surge protection device must have appropriate backup overcurrent protection.

Recommended backup protection

Schneider Electric specifies the following associated solutions for this reference:

• iK60N circuit breaker: 50 A, C curve, Icu 6 kA.
• gG fuse: 80 A, Icu 25 kA.

The final choice of backup protection must be made according to the available short-circuit current, installation conditions, and the coordination rules indicated by Schneider Electric.

Response time less than or equal to 25 ns

The Acti9 iPF K 65 has a response time ≤25 ns, allowing it to quickly limit transient impulses appearing in the installation.

Effective protection of equipment also depends on correct SPD installation, grounding, and keeping the connection conductors as short and direct as possible.

Protection against temporary overvoltages

Schneider Electric also specifies certain temporary overvoltage Ut values that the product can withstand:

• 337 V L-N: for 5 seconds.
• 442 V L-PE: for 5 seconds.
• 1,200 V N-PE: for 200 ms.
• 1,453 V L-PE: for 200 ms.

These values correspond to test conditions and must not be confused with the permissible permanent maximum voltages Uc during normal operation.

No remote signaling

Reference A9L15586 is supplied without remote signaling contact. Device status is monitored locally on the protector itself.

When an installation requires transmitting the SPD status to a monitoring or automation system, a variant specifically equipped with a remote contact must be selected.

DIN rail mounting

The protector is designed for clip-on installation on a DIN rail.

• Width: 72 mm.
• Height: approximately 81 mm.
• Depth: 69 mm.
• 9 mm pitches: 8.
• Equivalent width: 4 modules of 18 mm.
• Weight: approximately 335 g.
• Color: white RAL 9003.

The four-module format makes it possible to integrate a high-discharge-capacity 3P+N three-phase protection device into standard modular panels.

Terminals for conductors up to 25 mm²

Connection is made using tunnel terminals accessible from the top or bottom.

• Rigid conductor: up to 25 mm².
• Flexible conductor: up to 16 mm².
• Flexible conductor with ferrule: up to 16 mm².
• Stripping length: 11 mm.
• Tightening torque: 3.5 Nm.

In surge protection installations, it is especially important to reduce conductor length to minimize the additional voltage generated by inductance during impulse current flow.

Degree of protection

• Device protection rating: IP20.
• In suitable modular enclosure: up to IP40 according to the configuration indicated by Schneider Electric.

The protector must be installed inside an electrical panel or enclosure that provides the level of protection required by the environment.

Environmental conditions

• Operating temperature: -25 to 60 °C.
• Storage temperature: -40 to 85 °C.

Applications of the Schneider Electric A9L15586

The iPF K 65 can be used as part of a transient surge protection system in three-phase installations compatible with its characteristics.

• Main distribution boards.
• Secondary panels.
• Commercial installations.
• Tertiary buildings.
• Industrial installations.
• HVAC systems.
• Automation and control equipment.
• Installations with sensitive electronic equipment.
• TT networks.
• TN-S networks.

Cascade protection

Schneider Electric indicates that this model can be used as secondary load protection and installed in cascade with upstream protectors.

Cascade coordination makes it possible to distribute different protection levels throughout an installation and progressively reduce the overvoltage reaching sensitive receivers.

High-capacity Type 2 protection for three-phase networks

The Schneider Electric Acti9 iPF K 65 A9L15586 combines a high maximum discharge capacity of 65 kA, a nominal current In of 20 kA, and a protection level below 1.5 kV in a compact device for 3P+N three-phase installations.

Its compatibility with TT and TN-S networks, MOV + GDT technology, and the ability to coordinate it with other protectors make it suitable for stepped protection systems designed to reduce the effect of transient overvoltages on electrical and electronic equipment.

Important: the A9L15586 protects against transient overvoltages, but it does not replace a circuit breaker, an RCD, or protection against permanent overvoltages when required. To achieve the intended performance, the backup protection, earthing system, conductor cross-sections, and Schneider Electric installation instructions must be respected.
