Technical Specifications
Type TR relays, multi-contact attracted armature, IEC 61850 compliant
Modular and withdrawable case options, robust long-life design
Up to 20 contacts available
Low burden TR1: Suitable for tripping and auxiliary duties, no capacitance immunity needed
High burden TR2: Immune to capacitance discharge, suitable for remote applications, reliable with current-operated series repeat relays
TR relays available with instantaneous or time-delayed cut-off
Low burden TR312: Electrically reset, additional terminals for direct DC supply, reduces break duty
