Slocable Din Rail Mount DC Circuit Breaker Solar MCB 3 Phase
- Poles Number: 3P
- Rated Voltage: 750V DC
- Type: MINI 63 amp circuit breaker
(63 A) Din Rail Mount DC Circuit Breaker used in 3 Phase 3 Wire circuit, where 3 single pole MCB are mechanically connected in a way that if one Pole of the MCB trips other two will trip together. So if any one line of the circuit is overloaded (Suppose: In a three-phase motor if any single winding gets shorted with the body high current flows through that winding) all three poles get tripped.
Product Description
The Din Rail DC Circuit Breaker has the advantages of super-class current limiting performance, accurate relay protection, automatic device against overload, short-circuit fault, current limiting, arc extinguishing capability, etc. Through a large number of comprehensive scientific experiment, can be realized 3000Ah DC system in the main (sub ) screen, screen, screen protection relay between the total selective protection. The device adopts a special arc, current limiting system, which can quickly break the fault current of the DC power distribution system, greatly improving the stage difference coordination. Especially for the DC system in electric power engineering measure in protecting screen and electric screen appeared between the leapfrog tripping accidents, it has a series of excellent performances, which can avoid the failure.
