Feature
ETM8 series MCB is in complied with IEC 60898-1 standard. It has the certification of Dekra / KEMA, CE and CB .
The breaking capacity of ETM8 is 10KA, or 6KA.
The tripping type is B, C, D curve.
The rated current is (1A, 2A, 3A, 4A) 6A, 10A, 16A, 20A, 25A, 32A, 40A, 50A, 63A. The rated current is related to different area using for example one pole 10 to 16 ampere is normally used for lighting, 20 ampere to 33 ampere is normally used for kitchen and bathroom area, also used for air conditioner and other line equipment. Some customers will choose 2 pole, 40ampere to 63 ampere as main switch instead of isolator.
The tripping type is B, C, D curve.
Rated insulation voltage: AC, 230V, 240V, 230 / 240V (1 Pole); 400 / 415V (2 poles, 3 poles). DC, 250V 1P, 500V 2P, 750V 3P, 1000V 4P.
It has single pole (1p), double poles (2p), three poles (3p), and four poles(4p).
There is a position indicator equipped on the products, Red is on, Green is off.
The MCB terminals are IP20 protection which is designed for finger and hand touch safe to keep the safety during installation.
The ETM8 MCB can work reliably in harsh environment, in ambient temperature from -25°C to 55°C.
The electrical life can be up to 8000 operations and mechanical life up to 20000 operations, while the IEC requirement is only 4000 operations and 10000 operations.
It’s mounting type is to be mounted on din rail EN60715 35mm.

China circuit breaker, MCB factory, with high-quality products, good after-sales service and warranty policy, we have won the trust of many overseas partners, and many good feedbacks have witnessed the growth of our factory. Full of confidence and strength, we welcome customers to call and write to discuss and seek common future.
Miniature circuit breaker (abbreviated as MCB) is a circuit breaker product with a large range and quantity. Its main function is to provide protection for building electrical terminal power distribution devices. Because of its reliability and stability, it has become a widely used product in industry. Molded case circuit breakers have a current rating of up to 2000A. The maximum current rating of miniature circuit breakers is within 125A. Due to the difference in capacity between the two, in the specific work, the effective area of the molded case circuit breaker is also larger than that of the miniature circuit breaker, and the wires connected to it are also relatively thick, which can reach more than 35 square meters. Larger ones are more suitable to choose molded case circuit breakers.
