BenefitsNOARK Electric offers a complete range of 3pole Molded Case Motor Circuit Protectors (MCPs magnetic only)
These MCPs are for 3-phase asynchronous motors protection.
We offer MCPs in 6 frame sizes - M1M (150A)‚ M2M (250A)‚ M3M (400A)‚ M4M (600A)‚ M5M (800A) and M6M (1200A).
Each frame size offers a range of interrupting voltage ratings from 240-690Vac.
This series MCP conforms to global standards that include UL 489 / CSA C22.2 No 5 and IEC 60947-2.
The traditional system used for this purpose relies on 3 different devices.
These include a circuit breaker‚ a thermal relay and a contactor for motor switching.
In particular‚ when selecting these devices‚ different factors must be taken into consideration such as
- The rated motor power
- The type of motorː with cage rotor or with wound rotor
- The fault current at the point of the network where the motor is installed
