Briefing

The relay is suitable for using in the power circuits rated voltage up to 660V

Detailed

APPLICATION
The relay is suitable for using in the power circuits rated voltage up to 660V, rated current 500A 50Hz or
60Hz for overload and loss of phase protection or three phase induction motor and often combined with
B series AC contactor into magnetic starter.
T16 & T25 thermal relays have a friction trip operating mechanism with loss of phase running protection, pullback spring type operating mechanism (jump mechanism) with loss of phase protection  for T85 & T45, back jump mechanism for T170 & T105, main circuit with instrument transformer jump mechanism with loss of phase for T250 & T370.
