SELF POWERED CURRENT RELAY JRC 962 SP

Features

• Wide OC setting range
• Wide time setting range
• Fast reset time
• High drop-off / pickup ratio

Principle of Operation:

If a fault occurs at the distribution end and the respective protective relay operates but the corresponding CB fails to operate then the system may have to face catastrophic consequences. JRC-154 is a instantaneous and definite time over current relay that also monitors the non-potential contacts of the downstream protective relays. The relay is designed to trip the feeder end CB if the protective relay at the distribution end operates but its corresponding CB fails to operate.

Application:

JRC 966SP provides three pole, phase over current protection for distribution feeders and transformers. The relay measures the line current. If it exceeds a set threshold value, then the relay extends a trip signal according to the selected characteristic.
