RCMN100 Residual Current Relay

RCMN100 Residual Current Relay

Residual current monitor without digital display, used for leakage protection of pure AC permanent
Description
RCMN100 Series Introduction:
RCMN100 series residual current monitoring relay is an electrical safety preventive monitoring product without digital display. It is matched with CT and KCT precision residual current transformers and is used in AC grounded power grids. RCMN100 can accurately measure the residual current value of the power grid to the ground and judge the fault branch, and can transmit the residual current value to the host computer through the RS485 communication interface. One RCMN100 residual current monitoring relay can support 1 residual current monitoring. The product has the characteristics of strong anti-interference ability, high detection accuracy, and flexible networking.

RCMN100 Series Features:

● It is divided into A-type and AC-type residual current monitoring relays, which are separated from the transformer.
● Requires auxiliary power supply, and cannot automatically operate when the auxiliary power fails.
● Residual current can be set in multiple settings; action time can be set in multiple settings.
● With manual test and reset buttons.
● 35mm rail installation.
● Provide 2 modes of relays with and without digital display for selection.
● Products can be customized according to customer needs.
