Description

ETM7 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. 

ETM7 series MCB is in complied with IEC 60898-1 standard. It has the certification of KEMA / Dekra , CE and CB.
The breaking capacity of ETM7 is 10KA, or 6KA
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 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, 40 ampere 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, which is one inch breaker sizes per pole.
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 ETM7 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.
The mounting type is plug-in on top terminal ,wiring bottom.
