– 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.

– Adjustable start-up/delay timer allows 0-15 second delay to eliminate nuisance trips from high inrush or short overload conditions.

– Field-adjustable from 0-15 seconds to eliminate nuisance alarms due to start-up inrush or temporary overcurrent conditions.

– Contact ratings of 1.0A@240VAC or universal outputs of 0.15A@240VAC/VDC (N.O. models) and 0.2A@135VAC/VDC (N.C. models) for use with most standard motor control systems.

– 1.0A rating eliminates need for time delay relay

– Self-powered, split-core models simplify installation

– Status LED provides visual indication of setpoint trip and contact action.

– Constant hysteresis and linear response characteristic enhance accuracy to setpoint

– UL, CE approvals pending
