Description

ETM10 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.

ETM10 series MCB is in complied with IEC 60898-1 standard. It has the certification of Semko, CE and CB .
The breaking capacity of ETM10 is 6KA, or 4.5KA 
The tripping type is B, C or 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 10a to 16a 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.
Rated insulation voltage: 230V, 240V, 230 / 240V (1 Pole); 400 / 415V (2 poles, 3 poles)
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 ETM10 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.
