ETM3 series miniature circuit breaker are applicable to the low-voltage terminal distribution in the industry, civil building such as home and residence, energy, communication, infrastructure, lighting distribution system or motor distribution and other fields. They are used for the short circuit and overload protection, control and isolation. This mounting type MCB is used in almost all the countries and regions all over the world.
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 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.
The ETM3 MCB can work reliably in harsh environment, in ambient temperature from -5°C to 50°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.
