These relays can be manually tripped for
sequence inspection by pressing
manual trip bar (TR-0N/3, TR-5-1N/3).
A sequence inspection will be performed
when the test button is pulled out. When
the test button is pressed in, only the NC
contact will turn OFF. The original status
will be restored when the test button is
then released.(TR-N2/3 to N8/3)
●
Even if the reset button is carelessly
pressed, this relay trips without trouble
(Trip-free mechanism).
●
Trip indicator and manual trip bar permit
visual check of tripping status.
●
The setting dial uses a RC (Rated
Current) marking which is set to the
motor full load current.
