Schweitzer intros trip coil, lockout relay monitor

August 17, 2009 -- Schweitzer Engineering Laboratories, Inc. (SEL) announced the release of its SEL-2652 trip coil monitor, designed to provide critical power system information to engineers and operators. The self-powered device indicates circuit breaker status with a clearly visible external LED and a contact output for alarms or SCADA.

The company contends that today's power system depends on reliable circuit breaker operation; proactively monitoring the connections and circuit continuity of the circuit breaker trip coil and lockout relay gives operators confidence that the breaker is ready when needed.

"We wanted to provide constant monitoring of the health of trip circuits and lockout relays with an easy-to-use, reliable device," says Alex Bradley, SEL protection engineer. "SEL's design features an indicator light that's characterized by its high visibility and long working life. Our customers will know with certainty if the circuit breaker is ready to operate."

The SEL-2652 is easy to install, featuring a panel-mount design and the company's patented Connectorized terminal block. The one device is compatible with all systems from 48 to 125 Vdc. It is priced at $200.
