ARMAT IEK M10H Automatic Circuit Breakers for 80 and 100 A currents – double contact break for effective arc quenching
M10H ARMAT IEK circuit breakers for currents 80 and 100 A are designed for protection of circuits from overload and short circuit. Comply with GOST IEC 60947-2 and GOST IEC 60898-1. Design features ensure quick and effective arc extinction.
Advantages of M10H ARMAT IEK circuit breakers
- Pronounced current-limiting effect due to system with double break of main contacts.
- Two arc chutes with 24 plates in total — effective voltage drop on electric arc at moment of switching.
- Rated terminal tightening torque 5 N·m reduces transition resistance in the terminal and increases device energy efficiency.
- Tips on moving and fixed contacts made of silver composite AgC5 increase arc-resistant properties of contact system.
- Independent mechanism of free release reduces probability of contact group burning during switching.
