1.Application |
| |
JR-SS electronic overload relay is suitable for AC 50/60Hz, voltage up to 600VAC and currentup to 60A. It is used as overload and phase loss protection, independently adjustable startingand trip delay, visual current setting aid and trip indication, fail safe protection (N type) andelectronic shear pin function. The product conforms to IEC60947-1 standard. |
