How to read the relay protection terminal numbers

Identifying relay terminals is essential for correct installation and operation. Coil terminals, usually marked 85 and 86, connect to a low-power control source that activates the relay. The terminal numbering system used on IEC-style contactors, motor starters, and overload relays follows a standardized convention defined in IEC 60947-1 (Low-voltage switchgear - Part 1: General rules). Also principles of various protective relays and schemes including special protection. The protection and control devices in electrical equipment can be referred to by numbers, with appropriate suffix letters when necessary, according to the functions they perform. This standard defines letter codes that categorize equipment based on function, enabling engineers worldwide to interpret. To check a 4-pin relay, start by setting your multimeter to the ohms setting. Connect the multimeter leads to these terminals.
