Motor operator for remote control
3VA molded case circuit breakers can also be controlled remotely. Whether the circuit
breaker is controlled from "just" the other side of the closed cubicle door, or the breaker is
switched on via a control room, operator panel, etc., is irrelevant.
Motor operators are available as accessories for remote control of the circuit breakers.

Ergonomic design of circuit breakers, handles and control elements

Ergonomic handle
With its wide surface area, the ergonomic handle is designed to assist manual operation of
the circuit breaker. The white strip around the edge of the handle makes it easy to identify in
conditions of poor visibility. The additional rated operational current information stamped on
the white strip also significantly eases identification of the circuit breaker when it is one of
many breakers in a large switchboard installation.
