Products Description
ETM3 series MCB is in complied with IEC 60898-1 standard. It has the certification of Dekra / KEMA, CE and CB .
The breaking capacity of ETM3 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 ETM3 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.
