Product Description

Product Description

SONTUOEC  AC/DC  Miniature Circuit Breaker B,C, D Curve 1P,2P,3P,4P 63A 230/400V Breaking Capacity 6ka Overload current Protector MCB with busbar connection wire:
 The STM3-63 B,C,D curve 1amp up to 63Amp  mcb low voltage types of miniature electrical circuit breaker is mainly used in

AC50/60HZ single-pole 230V or two, three, four-poles 400Vcircuit for overload and short circuit protection as well as for unfrequent on-and off switching electric equipment and lighting circuit under normal condition. Used in lighting and electric motor distribution system. Characterized with novel structure ,light weight, reliable and excellent performance,high breaking capacity.It is conformity with GB10963,IEC 60898.1 standards. 

Technical Parameters:
Related Current(A)		Pole Number	Related Working  Voltage(V)	Breaking Capacity	Tripping Curve
1, 2, 3, 4, 5, 6, 10, 16, 20, 25, 32, 40, 50, 63		1, 2	230/240	3/4.5/6(KA)	B, C, D
		1, 2	230/400, 240/415
		2, 3, 4	400/415

Remark:
1. Type B is generally used for lighting, C type for general household appliances (market mainstream), D type motor protection.
2. Electrical life: standard 6,000 times, we can reach 10,000 times.     Mechanical life: standard 20,000 times (off-on), but working without electricity can be achieved 100,000 times.
3. Heat resistance: category 2 (temperature 55°C, relative humidity 95%).
