Terminal cover offset
The terminal cover offset always consists of two parts:
①
Rear insulating plate, provides insulation from the panel mounting plate
②
Front half, pushed over the molded case circuit breaker from the front
The insulating plate is fitted to the rear panel of the molded case circuit breaker and then
secured by two screws to the front half of the terminal cover. The terminal cover offset is also
secured by two additional screws to the molded case circuit breaker itself.
The terminal cover offset is compatible with:
●
Front bus connectors offset
Insulating plate and insulating plate offset
In certain cases it may be necessary to provide insulation from the panel mounting plate, see
section "Insulation measures" in chapter Insulating measures (Page 246). The insulating
plates for the 3VA molded case circuit breakers are designed for this purpose.
The insulating plate is fitted to the rear panel of the molded case circuit breaker and can be
installed in combination with phase barriers.
Potential applications:
●
Insulating plate:
–
Bus connectors extended
–
Non-insulated, straight conductors / terminals
●
Insulating plate, offset:
