Motor Protection Circuit-Breakers

A motor protection circuit breaker, or MPCB, is a specialized electromechanical device that can be used with motor circuits of both 60 Hz and 50 Hz. The motor protection circuit breaker can be considered a subtype of a thermal magnetic circuit breaker, but with additional functions that are specially designed to protect electric motors.

Thermal Overload Relays

A flexible range of thermal overload relays designed for TeSys D, K and F contactor ranges. They can be mounted directly under contactors for compactness, separately using accessories, be used as a stand-alone solution or mounted directly on to miniature contactors for advanced motor protection.Thermal overload relays are protective devices. They are designed to cut power if the motor draws too much current for an extended period of time. To accomplish this, thermal overload relays contain a normally closed (NC) relay.

TeSys LR2K

TeSys LR2K

Thermal relays, coordinated with TeSys K contactors, to protect from overloads motors up to 12 A (5.5 kW / 400 V). TeSys LR2K is a range of thermal overload relays from 0.06 kW to 5.5kW that can be used as a stand-alone solution or mounted directly on to TeSys K miniature contactors.
