ARMAT IEK M10N MA Automatic Circuit Breakers – for reliable operation of ventilation and fire extinguishing systems
M10N MA ARMAT IEK circuit breakers are equipped with electromagnetic release for protection against short-circuit currents. Independent mechanism of free release reduces probability of contact group burning during switching. Comply with GOST IEC 60898-1. Rated ultimate breaking capacity Icn — 10 kA.
Advantages of M10N MA ARMAT IEK circuit breakers
- Ceramic cheek of arc chute system effectively dissipates heat during switching of maximum short-circuit currents and increases switching resource.
- 14 ferromagnetic copper-plated plates on the arc chute accelerate arc extinction and increase switching resource.
- Protective output shutter prevents incorrect conductor connection and ensures safe installation.
- Mechanism of free release with instantaneous switching reduces negative influence of electric arc due to fast contact closing, which increases device service life.
- Two-position latch ensures convenient device mounting on DIN-rail, which speeds up process of installation and removal.
