Insulation Monitoring Relay
Measures the residual current in the respective circuit or branch of the system by means of a BENDER residual current transformer.
Ground fault protection: The RC48C monitors the residual current and operates in a fixed time if the current exceeds the preset value.
Ground continuity monitoring: The RC48C continuously monitors the cable and operates if:
the ground check conductor opens
the ground return conductor opens
the ground check conductor shorts to ground
