Claims

[Scope of utility model registration request]

Connect the set coil of a magnetic indicator that has a set coil and a reset coil to both ends of the coil of the small relay of an auxiliary relay that has several small relays that are sealed in metal and mold and whose contacts cannot be seen from the outside. ,
The reset coil is an auxiliary relay installed in a separate circuit, and when the small relay coil is energized by a fault signal or trip signal, a display is displayed by the indicator set coil installed at both ends of the auxiliary relay, and the display can be confirmed. An auxiliary relay characterized by having a circuit that can reset the display of the auxiliary relay to its original state by later turning on a reset switch for the display.
