Magnetic-thermal motor circuit breaker TeSys GV4, 3-pole, 115A, Icu=50kA, lever, EverLink terminals GV4PE115N

Magnetic-thermal motor circuit breaker – reliable protection for your installation

This three-pole TeSys GV4 motor circuit breaker is a robust solution for protecting electric motors. With a rated continuous current of 115A and a high short-circuit breaking capacity of 50kA at 400V, it ensures safety and reliable operation even under demanding conditions. The device’s integrated design in a single enclosure simplifies installation and guarantees durability.

Functionality and applications

Designed to protect three-phase motors up to 55kW at 400V, it provides comprehensive magnetothermal protection against overload and short-circuit conditions — as standard for this class of breakers. Additionally, the built-in phase-loss sensitivity enhances operational safety by minimizing the risk of motor damage during voltage imbalance. The adjustable thermal trip setting range (65-115A) allows precise tuning to match the load characteristics.

Construction and key features

The breaker is equipped with a lever for quick and intuitive operation. Everlink terminals ensure secure and lasting conductor connections, minimizing the risk of loosening during operation. The device has an IP40 protection rating, offering protection against access to live parts and ingress of solid objects larger than 1mm. The C characteristic enables slower response to brief current surges, making it ideal for motor starting applications. Additional auxiliary contact blocks (OF, SD) and voltage release units (MN, MX) can be mounted to expand functionality and adapt the device to specific installation requirements. Power loss is 13.8W.
