Schneider Electric RM35BA10 Harmony RM35BA Pump 5A 1CO 208-480V AC Control Relay

The Schneider Electric RM35BA10 is a Harmony RM35BA pump control relay that monitors overcurrent, undercurrent, phase sequence and phase failure on 3-phase or single-phase pump supplies. It switches a single 5 A C/O contact, measures 1-10 A current and 208-480 V AC voltage, and mounts on 35 mm DIN rail.

Selection Notes

RM35BA10's 1-10 A measurement range on the pump's current line catches both dry-running (undercurrent) and blocked-rotor/overload (overcurrent) faults with one relay, plus phase sequence and phase-loss on the 3-phase supply - four failure modes without four separate devices. The 11 A permanent overload input current rating means the sensing input tolerates sustained overcurrent faults through the 1-60 s startup inhibition window without damage. Its 208-480 V AC measurement range covers both 230/400 V and 460/480 V motor supplies from one part.
