Ergonomic Design Of Circuit Breakers, Handles And Control Elements - Siemens Sentron 3VA Manual

Motor operator for remote control
3VA UL molded case circuit breakers can also be controlled remotely. Whether the circuit
breaker is controlled from "just" the other side of the closed panel 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 ampere rating information stamped on the white
strip also significantly eases identification of the circuit breaker when it is one of many
breakers in a large panel installation.
