Presented by punjab switchgear the miniature circuit breaker is an innovative invention. The product is based on series b, c and dc and the accessories that transform the range into a most flexible system for protection, control, monitoring and switching.Its features include reboundless contact mechanism which prevents sparking/erosion of contacts; superior arc runner based on current-limiting; blowout rapid extinction magnetic system, permits exceptionally low let-through energy; designed to withstand up to 25 ka short circuit currents; silver graphite tips for fixed contact, silver-plated moving contact, incoming and outgoing terminals ensure extended life span and prevent contact welds while withstanding higher short circuit breaking levels; unique self-lubricating special plastics components; angular hot air exhaust vents ensure diversion of gases induced at the time of fault clearance, away from the mcbs, quickly and effectively, besides preventing ingress of dust; and din rail mounting is snap fixing with two stop locations. Technical specifications: rated voltage - 240/415 v ac and 220 v dc; rated current: regular 6, 10, 16, 20, 25, 32, 40, 50 and 63 a; number of poles - 1, 2, 3 and 4; breaking capacity - 10,000 a as per is: 8828/96; mounting position - optional fixing - snap fixing on 35 mm din-rail; type of connection - single connection or collective on bus bars; and service life - 5,00,000 mechanical operations.
