Magnetothermal Circuit Breaker 4-6.3A

The Schneider Electric TeSys Deca GV2ME10 is a 3-pole motor circuit breaker / thermal-magnetic motor protection circuit breaker designed for the protection and manual control of three-phase motors. It features adjustable thermal protection from 4 to 6.3 A, a fixed magnetic trip of 91 A, and is suitable for motors up to 2.2 kW at 400/415 V. Its combination of overload, short-circuit, and phase-loss protection brings several motor protection functions together in one compact device.

The GV2ME10 reference belongs to Schneider Electric’s TeSys Deca GV2 range and uses front control via start and stop pushbuttons. It includes screw terminals, supports direct mounting on a 35 mm DIN rail, and offers a high breaking capacity, reaching 100 kA at 400/415 V AC in accordance with IEC 60947-2.

Thermal-magnetic motor protection circuit breaker from 4 to 6.3 A

The GV2ME10 incorporates a thermal-magnetic trip unit specifically designed for motor protection.

Its thermal protection can be adjusted between:

• Minimum current: 4 A.
• Maximum current: 6.3 A.

The setting must be adjusted according to the rated current shown on the motor nameplate and the actual operating conditions of the installation.

Thermal overload protection

The thermal part of the motor protection circuit breaker protects against sustained overloads. If the motor draws a current higher than the set value for a certain period of time, the device opens the circuit to prevent excessive heating of the windings and wiring.

As it is adjustable between 4 and 6.3 A, the same GV2ME10 can be adapted to different motors within this current range.

Magnetic short-circuit protection

The magnetic protection provides a fast response to high short-circuit currents.

Schneider Electric specifies a magnetic trip current of 91 A for the GV2ME10.

This protection operates independently of the thermal setting and is designed to disconnect the circuit quickly in the event of high-current faults.

Phase-loss sensitivity

The Schneider Electric GV2ME10 features phase-loss sensitivity in accordance with IEC 60947-4-1.

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

3 poles for three-phase motors

The motor protection circuit breaker has a 3-pole configuration, suitable for three-phase motor supply circuits.

• Number of poles: 3P.
• Network type: AC.
• Frequency: 50/60 Hz.
• Maximum rated operational voltage Ue: 690 V AC.

Up to 2.2 kW at 400/415 V

Compatible motor power depends on the supply voltage. Schneider Electric specifies:

• 400/415 V AC: up to 2.2 kW.
• 500 V AC: up to 3 kW.
• 690 V AC: up to 4 kW.

Final selection should be made primarily based on the motor’s actual rated current, which must fall within the 4 to 6.3 A adjustment range.

100 kA breaking capacity at 400 V

The GV2ME10 offers a high ultimate breaking capacity Icu, which varies according to the operating voltage:

• 230/240 V AC: 100 kA.
• 400/415 V AC: 100 kA.
• 440 V AC: 50 kA.
• 500 V AC: 50 kA.
• 690 V AC: 3 kA.

In a conventional 400 V three-phase network, the device therefore achieves an Icu of 100 kA in accordance with IEC 60947-2.

Service breaking capacity Ics

Schneider Electric specifies a service breaking capacity Ics equal to 100% of Icu at 230/240 V, 400/415 V, 440 V, and 500 V.

At 690 V, Ics corresponds to 75% of Icu.

This high capacity allows the motor protection circuit breaker to be used in installations where significant short-circuit current levels may occur, always within the manufacturer’s specified conditions.

AC-3 and AC-3e categories

The GV2ME10 is designed for motor protection and control applications in the following categories:

• AC-3.
• AC-3e.

These categories are related to the starting and switching off of squirrel-cage motors, making the device especially suitable for motor control panels and machinery.

Manual control via pushbuttons

The GV2ME10 includes a front pushbutton control system that allows the motor to be manually switched on and off.

In this way, the same device can provide:

• Manual switching on.
• Manual switching off.
• Overload protection.
• Short-circuit protection.
• Phase-loss protection.

To automate remote start and stop, it can be combined with a compatible TeSys contactor.

Suitable for isolation

The Schneider Electric GV2ME10 is suitable for isolation or disconnection in accordance with IEC 60947-1.

This allows it to be used as a disconnecting device inside the panel during maintenance operations, always following the applicable safety procedures.

Complete motor protection in a compact format

The Schneider Electric TeSys Deca GV2ME10 combines adjustable thermal protection, instantaneous magnetic protection, phase-loss sensitivity, and manual control in a single compact device. Its 4 to 6.3 A range allows it to protect three-phase motors up to 2.2 kW at 400/415 V when their rated current falls within the adjustable range.

Its high breaking capacity of 100 kA at 400/415 V, the possibility of combining it with TeSys contactors, and its DIN rail mounting make the GV2ME10 a particularly suitable solution for motor starters, machinery, and professional automation panels.

Important: the GV2ME10 is not a residual current device and does not provide protection against earth leakage currents. Its function is to protect motors against overloads, short circuits, and phase loss. When residual current protection is required, a suitable independent device must be added.
