ETM10 MCB
Designed for DIN rail mounting, the ETM10 breakers are widely used in both residential and commercial electrical systems. They support rated currents from 6A up to 63A and have a breaking capacity of either 4.5kA or 6kA, depending on the model. Standard operating voltages include AC 230/400V or 240/415V, and DC versions can be provided upon customer request.
Manufactured to meet IEC/EN 60898-1 standards, the ETM10 series has been certified by Semko, CE, and CB, ensuring high safety and compliance for global markets. OEM and private label options are available for manufacturers seeking customised solutions.

The ETM10 series miniature circuit breakers (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.
These breakers are available in 1P, 2P, 3P, and 4P versions, with tripping characteristics offered in B, C, or D curve types to meet different protection needs. Depending on the model, they provide a breaking capacity of either 4.5kA or 6kA.
The rated current ranges from as low as 1A to 63A, covering typical values like 6A, 10A, 16A, 20A, 25A, 32A, 40A, and 50A. For instance:
- 10A to 16A (single pole) is commonly used for lighting circuits.
- 20A to 32A suits heavier loads like kitchen appliances, bathrooms, or air conditioners.
- Higher ratings such as 40A to 63A (two-pole models) are often selected by users as main switches instead of traditional isolators.
The ETM10 series supports various rated insulation voltages:
- AC 230V / 240V for single-pole models
- AC 400V / 415V for two- or three-pole units
For added user safety, each unit includes a clear visual indicator—red indicates ON, green means OFF. The terminals are IP20-rated to prevent accidental contact during installation or maintenance.
Designed to perform reliably even in challenging environments, ETM10 MCBs operate within a temperature range of -5°C to 50°C. They also offer an extended service life, with an electrical endurance of up to 8,000 cycles and mechanical endurance reaching 20,000 cycles—double the minimum requirements specified by IEC standards.
