Ex9 Series - M: Molded Case Motor Circuit Protectors

NOARK Electric offers a complete range of 3 pole Molded Case Motor Circuit Protectors (MCPs, magnetic only) which are used to protect the three phase asynchronous motors in six frame sizes: M1M - 150 A, M2M - 250 A, M3M - 400 A, M4M - 600 A, M5M - 800 A, and M6M - 1,200 A. Each frame size offers a range of interrupting voltage ratings from 240-690 Vac and 250-600 Vdc. This series MCP conforms to global standards that include UL 489, CSA C22.2 No 5.1 and IEC 60947-2. 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.

The Ex9 Series - M offers

  • Instantaneous trip ability and a new patented arc extinguishing design
  • New patented technology reduces the manual operating force
  • High-quality compact modular with energy saving and environmentally friendly design
