– Serves as an electronic proof-of-operation; detects current draw changes in motors when they encounter problems such as pumps running dry or pending bearing failure.

– Non-intrusive, less expensive to install than differential pressure flow sensors or thermal switches. Much quicker response time than Class 10 overload relays.

– Start-up/delay timer provides 2 second delay to avoid nuisance tripping from high inrush or short

overload conditions.

– Factory calibrated trip timer set to 2 seconds to eliminate nuisance alarms due to start-up inrush or temporary overcurrent conditions.

– Contact rating of 10A@240VAC provides adequate switching capacity for use in most motor control systems.

– Eliminates need for separate time delay relay Choice of 24VAC/DC or 120VAC supply models

LED provides indication of trip point contact status Setpoint adjustable from 1-50A

– 0.5% accuracy, precise time delay setpoint, constant hysteresis, linear response and low frequency capability

– UL, CE approvals pending
