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. Each frame size offers a range of interrupting ratings at 240-690 Vac and 250-600 Vdc. 5-Year limited warranty.
