TeSys GV3 Motor Circuit Breaker 3P 70-80A EverLink

The Schneider Electric TeSys Deca GV3P80 is a 3-pole motor circuit breaker or thermal-magnetic motor protection circuit breaker, designed to protect three-phase motors against overloads, short circuits, and phase loss. It features a thermal adjustment range of 70 to 80 A, a fixed magnetic trip of 1,120 A, and can protect motors up to 45 kW at 400/415 V AC. Its high breaking capacity reaches 50 kA Icu at 400/415 V, while the EverLink power terminals provide a robust and durable connection for industrial applications.

The GV3P80 reference belongs to the TeSys Deca GV3 range, frame size 3, developed for protecting higher-power motors while maintaining a compact 55 mm width. It can be mounted directly on a 35 mm DIN rail or screwed onto a plate, and features a front rotary handle for switching on, switching off, and resetting.

Adjustable thermal-magnetic protection from 70 to 80 A

The GV3P80 integrates a thermal-magnetic trip unit. The thermal part can be adjusted between 70 and 80 A to adapt protection to the motor rated current.

• Rated current In: 80 A.
• Thermal adjustment range: 70-80 A.
• Number of poles: 3P.
• Protection type: thermal and magnetic.
• Application: three-phase motor protection.

The setting must be adjusted according to the rated current indicated on the motor nameplate and the actual operating conditions. Motor power in kW is a selection reference, but the main parameter for correctly setting thermal protection is the motor operating current.

Thermal overload protection

The thermal function protects the motor when a current higher than the set value flows for an extended period. This situation may occur due to mechanical overload, partial blockage, abnormal operation, or other conditions that cause excessive heating of the windings.

By integrating this thermal protection, the GV3P80 can directly provide motor overload protection without the need for a separate thermal overload relay when the motor protection circuit breaker is correctly selected and adjusted.

1,120 A magnetic trip

Instantaneous short-circuit protection is provided by a fixed magnetic trip of 1,120 A, equivalent to approximately 14 times the 80 A rated current.

This fast action opens the circuit when a high fault current occurs, protecting the motor, conductors, and associated components from the thermal and electrodynamic effects of a short circuit.

Phase-loss sensitivity

The Schneider Electric GV3P80 incorporates phase-loss sensitivity in accordance with IEC 60947-4-1.

This feature is especially important in three-phase motors, as operation with one phase missing can cause high current imbalance, loss of torque, and motor overheating.

Up to 45 kW at 400/415 V

The maximum motor power specified by Schneider Electric depends on the supply voltage:

• 400/415 V AC: up to 45 kW.
• 500 V AC: up to 45 kW.
• 690 V AC: up to 55 kW.

On a typical 400 V three-phase network, the GV3P80 is therefore intended for motors up to 45 kW, provided that the motor rated current falls within the adjustable range of 70 to 80 A.

High breaking capacity of 50 kA at 400 V

The GV3P80 offers a high short-circuit interruption capacity. Schneider Electric specifies the following Icu values:

• 230/240 V AC: 65 kA.
• 400/415 V AC: 50 kA.
• 440 V AC: 50 kA.
• 500 V AC: 12 kA.
• 690 V AC: 6 kA.

Its 50 kA breaking capacity at 400/415 V makes it suitable for professional and industrial installations with high short-circuit current levels, provided that installation calculations confirm its suitability.

Service breaking capacity Ics

Schneider Electric specifies the service breaking capacity Ics as a percentage of Icu:

• 230/240 V AC: 100% of Icu.
• 400/415 V AC: 60% of Icu.
• 440 V AC: 60% of Icu.
• 500 V AC: 50% of Icu.
• 690 V AC: 50% of Icu.

At 400/415 V this corresponds to an Ics of 30 kA.

Utilization categories

The GV3P80 is classified as:

• Category A according to IEC 60947-2.
• AC-3 according to IEC 60947-4-1.

The AC-3 category is associated with starting and stopping squirrel-cage motors and confirms the device’s specific orientation toward motor protection and control applications.

EverLink terminals

One of the standout features of the GV3P80 is its EverLink power connection system. This Schneider Electric technology uses a conductor creep compensation system that helps maintain contact pressure over time.

EverLink technology is designed to reduce the effects that can cause loss of pressure in an electrical connection, such as:

• Progressive conductor deformation.
• Thermal cycling.
• Vibrations.
• Normal mechanical stresses in the installation.

This helps provide a reliable and long-lasting power connection, especially useful in machine control panels and industrial installations subject to continuous operation.

EverLink terminal tightening torque

For EverLink terminals, the technical documentation specifies different tightening torques depending on the conductor cross-section used:

• 25 mm² conductor: 5 Nm.
• 35 mm² conductor: 8 Nm.

The tightening torque specified by Schneider Electric must be respected during installation to ensure proper EverLink performance.

Rotary handle operation

The GV3P80 includes a front rotary handle that allows manual switching on, switching off, and resetting.

The device can be used for local motor operation. When automatic operation or remote control is required, it can be combined with a properly sized TeSys contactor.

Suitable for isolation

Schneider Electric declares the GV3P80 suitable for isolation in accordance with IEC 60947-1.

This function allows it to be used as an isolating device within the appropriate maintenance and safety procedures.

Operating voltage up to 690 V

• Rated operational voltage Ue: up to 690 V AC.
• Frequency: 50/60 Hz.
• Rated insulation voltage Ui: 690 V AC.
• Rated impulse withstand voltage Uimp: 6 kV.
• Conventional thermal current Ith: 80 A.

Power dissipation

Schneider Electric specifies a power dissipation of 8 W per pole.

This value should be considered when calculating the total heat dissipation of the panel, especially when several power devices are installed in the same enclosure.

DIN rail or panel mounting

The GV3P80 supports two main installation methods:

• Clip-on mounting on a 35 mm symmetrical DIN rail.
• Panel mounting using 3 M4 screws.

It can be installed in either vertical or horizontal position within the conditions specified by Schneider Electric.

Schneider Electric GV3P80 dimensions

• Width: 55 mm.
• Height: 132 mm.
• Depth: 136 mm.
• Weight: approximately 0.96 kg.

• Storage temperature: -40 to 80 °C.
• Operating altitude: up to 3,000 m.
• Fire resistance: 960 °C according to IEC 60695-2-11.
• Vibration resistance: up to 4 gn between 5 and 300 Hz under specified conditions.

Combination with TeSys contactors

The GV3P80 can be combined with Schneider Electric TeSys contactors to create a complete motor starter.

In this configuration:

• The GV3P80 provides thermal and magnetic protection.
• The contactor performs remote electrical switching on and off.
• Auxiliaries allow signaling, interlocking, and automation functions to be implemented.

Since thermal protection is already integrated, there is no need to add a separate thermal overload relay when the GV3P80 is used within its adjustment range and according to Schneider Electric coordination guidelines.

Applications of the Schneider Electric GV3P80

Its 70 to 80 A range and its capacity for motors up to 45 kW at 400/415 V make it suitable for many industrial applications:
