Combining the TeSys H Motor Starter with Circuit Breakers

Overview

WARNING
HAZARDOUS VOLTAGE AT THE MOTOR Check the safety function each time the TeSys H motor starter trips. After every short-circuit, in the case of short-circuit protection according to type-1 coordination, a TeSys H motor starter may be defective. Replace it before restarting. Failure to follow these instructions can result in death, serious injury, or equipment damage.

For use in North America

WARNING
HAZARD OF FIRE OR ELECTRIC SHOCK The opening of the branch-circuit protective device may be an indication that a fault current has been interrupted. To reduce the hazard of fire or electric shock, current-carrying parts and the other components of the controller should be examined and replaced if damaged. Failure to follow these instructions can result in death, serious injury, or equipment damage.

WARNING

HAZARD OF FIRE OR ELECTRIC SHOCK

The opening of the branch-circuit protective device may be an indication that a fault current has been interrupted.
To reduce the hazard of fire or electric shock, current-carrying parts and the other components of the controller should be examined and replaced if damaged.

Failure to follow these instructions can result in death, serious injury, or equipment damage.

The TeSys H motor starter can be combined with the following magnetic motor circuit breakers:

GV2L: rotary knob type Ue = 500 V
GV2LE: rocker lever type Ue = 415 V

Group Protection with Type-1 Coordination According to IEC/EN 60947-4-2 for 415 V Maximum Voltage

This table gives the maximum short circuit current that can be protected by association of a GV2 circuit breaker and several TeSys H motor starters. The total nominal current of all TeSys H motor starters combined together should not exceed the maximum current of the GV2L/GV2LE circuit breaker associated for group short circuit protection.
