Molded Case Circuit Breaker(MCCB)

Application: This series moulded case circuit breaker is one of new type breakers which our company adopts international advanced desigin,manufacture technology to develop.The rated insulating voltage is 950V.Suitable for AC 50Hz(60Hz).Rated working voltage 690v or below,rated working current is 12.5A to630A of circuit and used in distributing electric energy.Non-frequent making and breaking in the normal conditions and protecting when circuit and installation are overload,short circuit and lacking voltage.Rated shell-rack and the breaker whose current is under 400A,take protection effect when mouse cage motors non-frequent start,breakering off working and protecting from overload,short circuit and lacking voltage,The product conforms to GB14048.2,IEC 60947-2standards. .CE,ROHS,CERTIFICATED .Quality guarantees 2 years .Professional manufacture for 10 years We can supply all kinds of MCCB ODM Rated Current of Release (A) Thermodynamic Release (ambient Temp +40) Operational Current of Magnetic Release (A) 1.05In (Cold State inoperative time (h) 1.30In (thermal State) Operative Time (h) In≤63 ≥1 1 10In±20% 63In≤100 ≥2 2 10In±20% 100In≤630 ≥2 2 5-10In±20% Rated Current of Release (A) Thermodynamic Release (ambient temp +40) Operational Current of Magnetic Release (A) 1.0In (cold state) operative time (h) 1.20In (thermal state) operative time (h) 1.50In (cold state) operative time (h) 1.01In (thermal state) operative time (h) 12.5≤In≤400 ≥2 2 ≤4min 2STp10S 12In±20% Technical Specifications Type Rated Current (A) Poles Rated Insulation Voltage (V) Rated Operating Voltage (V) Ultimate Short Circuit Breaking Capacity Arcing Over Distance (mm) CKNS-100 12-100 3, 4 950 690 18-150 0 CKNS-160 16-160 25-150 CKNS-250 160-250 25-150 CKNS-400 200-400 35-150 CKNS-630 315-630 35-150
