ETM2 MCB
ETM2 Series is a high-performance Miniature Circuit Breaker (MCB) fully compliant with IEC 60898-1 standard, designed for overcurrent protection in residential, commercial, and light industrial electrical installations. It has the certification of Dekra / KEMA, CE and CB .
The rated current is related to different areausing for example one pole 10 to 16 ampere is normally used for lighting, 20 ampere to 33 ampere is normally used for kitchen andbathroom area, also used for air conditioner and other line equipment.
The electrical life can be up to 8000 operations and mechanical life up to 20000 operations, while the IEC requirement is only4000 operations and 10000 operations.
