• Simple & reliable construction

• Compact panel mounting case

• Sensing points are high impedance type and can be used on any type of trip circuits.

• Supervises both pre closing and post closing conditions.

• Checks ON: Control voltage, Interlocks, Solenoid Coil wiring and TRIP coil

healthiness.

• Checks the Trip coil loose connection (>300 ohm) or shorting (< 10 ohms).

• Supervises the link cable between C. R. Panel and C. R. Panel Trip circuit

connections.

• Very low burden on Aux. supply. (Less than 3VA).

• Self TEST facility for routine maintenance check.

• Immune to momentary dips in control voltage
