Improve system reliability with SEL trip coil, lockout relay monitoring
Schweitzer Engineering Laboratories Inc. (SEL) offers the SEL-2652 Trip Coil Monitor, which proactively monitors connections and circuit continuity of the circuit breaker trip coil and lockout relay. See wiring diagram.
Power systems depend 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. Schweitzer Engineering Laboratories Inc. (SEL) offers the SEL-2652 Trip Coil Monitor to provide this critical information to engineers and operators.
The self-powered SEL 2652 indicates circuit breaker status with a clearly visible external LED and a contact output for alarms or supervisory controls or data acquisition (SCADA).
"We wanted to provide constant monitoring of the health of trip circuits and lockout relays with an easy-to-use, reliable device," said 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," Bradley says.
The SEL-2652 is easy to install, featuring a panel-mount design and a SEL Connectorized terminal block. This one device is compatible with all systems from 48 to 125 V dc, reducing on-hand inventory and allowing engineers to efficiently monitor circuit health, improve safety, and reduce maintenance times.

Annual Salary Survey
In a year when manufacturing continued to lead the economic rebound, it makes sense that plant manager bonuses rebounded. Plant Engineering’s annual Salary Survey shows both wages and bonuses rose in 2012 after a retreat the year before.
Average salary across all job titles for plant floor management rose 3.5% to $95,446, and bonus compensation jumped to $15,162, a 4.2% increase from the 2010 level and double the 2011 total, which showed a sharp drop in bonus.
