The ETM8 series miniature circuit breakers (MCBs) are designed for low-voltage terminal distribution across a wide range of applications, including residential buildings, commercial facilities, industrial settings, energy systems, communication networks, and infrastructure projects. They are commonly used for protecting circuits against short circuits and overloads, while also providing control and isolation functions.
Widely adopted around the globe, the ETM8 MCBs are compatible with standard DIN rail mounting (EN60715, 35mm), making them suitable for universal installations. They are built in compliance with the IEC/EN 60898-1 standard and come certified by Semko, CE, and CB—ensuring performance and safety in both local and international markets.
The breaking capacity of ETM8 is 6kA or 10kA or 15kA .
The rated current ranges from as low as 1A to 63A
The ETM80 series supports various rated insulation voltages:
- AC 230V / 240V for single-pole models
- AC 400V / 415V for two- or three-pole units
