| The
relay is suitable for using in the power
circuit up to rated voltage 660V,rated
current 500A 50Az or 60Az for overload
and loss of phase protection of three
phases induction motor and often combined
with B series AC contactor into magnetic
starter.
T16
& T25 thermal relays have a friction
trip operating mechanism with loass
of phse running protection, pulback
spring trip operating mechnism (jump
mechanism)with loss of phase protection
for T85 & TSA45,backpack jump mechanism
for T170 & 105,main circuit with
instrument transformer humt mechanism
with loss of phase for T250 & T370. |
