Overall and Installation Dimension(mm)
Residual-current circuit breaker (RCCB), is a device that quickly breaks an electrical circuit to prevent serious harm from an ongoing electric shock. Injury may still occur in some cases, for example if a human falls after receiving a shock, or if the person touches both conductors at the same time. If the RCD device has additionally overcurrent protection integrated in the same device, it is referred to as RCBO.
The ETEK range of residual current circuit breakers without integral overload protection (RCCBs), provided protection solutions to a wide range of applications.

Dear Sir/Madam,Thank you for giving our company support in this year.The Chinese traditional Spring Festival is coming,We will have a holiday from Feb. 4th to Feb. 21th 2021.Sorry for any inconvenience caused.
ETEK ELECTRIC Wish you a happy Christmas and a happy holiday season. Thank you very much for your support of our cooperation over the past year,see you next year.
According to the usage, there are 3 types of motor protection circuit breakers: 1. AC contactor is used for starting and breaking of the
