ETM8L series residual current operated circuit breakers protects against injury and death caused by electric shock by detecting an imbalance between the outgoing and incoming total current of a given number of circuits, such as prevent earth leakage, direct or indirect contact electric shock and other faults, and are applicable to low-voltage terminal power distribution in such fields as industry, commercial environments civil construction (home), energy, communication and infrastructure. They provide short-circuit protection, leakage protection and isolation protection. RCCB will detect any earth fault, so that RCCB are using nowadays instead of ELCB. Residual Current Circuit Breaker (RCCB) is also known as Residual Current Breaker (RCB) or Residual Current Protective Device (RCD).

ETM8L RCCB rated current is 25-100 ampere, 25A, 40A, 63A, 80A, 100A.
The short circuit breaking capacity is 10 KA and 6 KA
The rated residual operating current is 10 to 300 mA
Rated insulation voltage: 230 Volt or 240 Volt for 2poles and 400 Volt or 415 volt for 4poles
It has double poles (1P+N) , and four poles (3P+N)
There is a position indicator equipped on the products, Red is on, Green is off.
The RCCB Equipped with a test button to check the health of the device.
Equipped with neutral terminal
The RCCB terminals are are IP20 protection which is designed for finger and hand touch safe to keep the safety during installation.
The ETM8L can work reliably in harsh environment, in ambient temperature from -25°C to 55°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.
