Product Introduction
ETM7RF series RCBO 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 provide leakage protection, short-circuit protection, overload protection, and isolation protection, which can protect the human from hurting caused by leakage of current, at the main while they can protect the circuit and appliances from the secondary accident caused by overload and short circuit.
ETM7RF series RCBO is in complied with IEC 61009-1standard.
The breaking capacity of ETM8LE is 10KA, or 6KA
The tripping type of short circuit is B, C curve.
The rated current is 6A, 10A, 16A, 20A, 25A, 32A, 40A. 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 equipment.
The sensitivity current of Residual Current, or Earth Leakage tripping is 10mA, 30mA, 100mA, while 10mA and 30mA is mainly used in circuit of bath room and kitchen to protect the human from electric shock.
The tripping type of Residual current is AC or A class. AC class Tripping is ensured for sinusoidal, alternating currents, whether they be quickly applied or slowly increase . A class Tripping is ensured for sinusoidal, alternating residual currents as well as for pulsed DC residual currents, whether they be quickly applied or slowly increase .
Rated voltage: 230V/ 240V ( Phase & Neutral)
There is a position indicator equipped on the products, Red is on, Green is off.
The RCBO terminals are IP20 protection which is designed for finger and hand touch safe to keep the safety during installation.
The ETM7RF RCBO 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.
It’s mounting type is to be mounted Plug in on Pan assemnly
