Description

The explosion-proof automatic switch with remote switching-off - -40001 is intended for the use in three-phase electric networks of an alternating current with the isolated neutral of the transformer in the coal and slate mines dangerous on gas (metane) and a coal dust, for protection of electric plants against the short-circuit current and for infrequent operative switching on and off of the electric circuits at the normal operating modes of three-phase circuits with a voltage of 660 and 1140 V. Explosion proof version is PB 3B . The level of protection - JP54 to GOST 14254-96.

Reference designation

-40001 5: - automatic switch; - explosion proof; 400 - rated current, ; - remote switching-off; 1 - design number; 5 - climatic version and category of location to GOST 15150-69.

Operating conditions:

Altitude above sea level is not more than 1000 m; Ambient air temperature is from -10 +35; Relative humidity of ambients is up to (982)% at the temperature (352); Carbon dust content in the surrounding environment is less than 1200 /3; Voltage oscillation in the electric circuit has to be from 0,85 1,1 Unom.
