Features:
The traditional system used for this purpose is based on three different devices:
a circuit breaker for protection against short-circuit, a thermal relay for protection against overload and phase loss or unbalance of phase, and a contactor for motor switching.
In particular, when selecting these devices, different factors must be taken into consideration, such as:
The motor power, The diagram and type of starting, The type of motor: with cage rotor or with wound rotor, The fault current at the point of the network where the motor is installed
offers a complete range of 3 pole Molded Case Motor Circuit Protectors (MCPs, magnetic or short circuit protection only) which are used to protect the cables feeding three phase motors in six frame sizes: M1M - 150 A, M2M - 250 A, M3M - 400 A, M4M - 600 A, M5M - 800 A, and M6M - 1200 A.
