Ground fault monitor for grounded AC/DC systems - Residual Current Monitor Software Version: D55 V2.0 Werk-Nr 0203020067 The RCMA470LY monitors for ground fault leakage current in grounded & high-resistance grounded single & three-phase AC, pulsed DC, and pure DC type systems (Type B). Features include two seperately adjustable setpoints from 30mA...3mA for the main alarm and 50% of the set value for the pre-alarm, LED meter display (0-100%), adjustable time delay from 0...1 s for the pre-alarm and 0...10sec for the main alarm, fault storage, 2 DPDT alarm relays which can be set for normally energized and normally de-energized operation. An external BENDER current transformer is required for operation. DIFFERENZSTROMUBERWACHUNGSGER The RCMA470LY has a lower starting setpoint range than the RCMA471LY, and uses smaller current transformers. No transformer included.

8A/250V 50/60Hz 1/3HP 1-Phase Monitoring Relay - Due to the ON-delay T2, current peaks (OVER function) or current drops (UNDER function), which may occur during closing, do not result in a change to the relay state, for example suppression of the starting current during motor acceleration. The delay time T1 prevents the relay from picking up and releasing - A green LED signalizes the applied supply voltage. A yellow LED indicates the relay status. Current monitoring without memory (NO MEMORY) (Fig. IIIa) When the value of the monitored alternating or direct current has reached the threshold set at the front panel, and the set delay time T1 has elapsed, the output relay releases. As soon as the current reaches the hysteresis value, the relay picks up again. Current monitoring with memory: (Fig. IIIb) When the set threshold value has been reached and the set delay time T1 has elapsed, the output relay releases and remains in this state, even when the measured current reaches the set hysteresis value again. A reset is performed by switching the supply voltage off and on. 23mm wide 78mm tall 104mm OAD - 4 controls on front panel, tiny little Überwachungsrelais.
