Additional Details

Operation:

The JRF 014 is microprocessor based frequency relay The relay can be configured for 2 stage under frequency relay, two stage over frequency relay or Under / Over frequency relay. The relay's operating time can be programmed. The relay measures line frequency and if it exceeds the set threshold in case of over frequency or if it is less than set threshold in case of under frequency then relay extends a trip signal after an operating time

Features:

Two stage of frequency protection

Digital display of line frequency

Draw out case 144x144 mm

Application:

The relay provides time graded over / under frequency protection. Used in industrial plants having captive power generators requiring under frequency protection.

With almost more than a decade of experience and rich technological expertise, we are able to offer a precision designed range of Electrical Protection Instruments.
