Circuit breaker VA04-36 400A-320A
We realize the automatic circuit breakers VA04-36 340010 and VA04-36 840010 for 400А and 320А in a molded case, of all types. Warranty 2 years! In the presence of switches VA0436 400A ready for shipment.
Technical description VA04-36: Circuit breakers VA 04-36 for rated current 320A, 400A and for other currents are manufactured with electromagnetic, thermal and electromagnetic releases. Circuit breakers VA 04-36, VA-0436- 3-pole, manufactured for alternating current, and circuit breakers VA 04 36, VA04-36 2-pole manufactured for direct and alternating (Hz 50) current.
VA 04-36 automatic devices are designed to switch the current in normal mode and protect against overloads of unacceptable duration, during short circuits, as well as for infrequent, up to 19 times a day, operational outages of electrical circuits with a rated voltage of up to 660 V AC of frequency 50 and 60 Hz and up to 440 V DC. AC circuit breakers can also be used to protect infrequent direct starts of induction motors in the AC-3 application category. VA 04 36 circuit breakers are available with thermal and electromagnetic maximum releases, only with electromagnetic maximum current releases and without maximum current releases. Circuit breakers can be equipped with a zero-voltage release, shunt release, free contacts and an electromagnetic drive. Automatic available in stationary versions - front, rear and combined connection and retractable version.
