Benefits
The circuit breaker provides many different advantages:
● Low space requirements
The 3WL10 circuit breakers are extremely compact. 3-pole and 4-pole devices of size 0
fit into a 400 mm wide switchboard panel. Two 3-pole 3WL10 circuit breakers can also be
installed side by side in a 600 mm wide switchboard panel.
The flexibly mountable connections and installation options of the device enable a
considerable amount of space to be saved in the switchboard. For example, due to the
possibility of mounting the bar flat terminals directly on the front and the positioning the
device on the rear in wall-mounted configuration, which is unusual for an air circuit
breaker.
The 3VA27 molded case circuit breakers provide a compact solution up to 1600 A. A
spring charging motor and/or a metering function can optionally be integrated in the
device.
● Highly modular design
Components such as auxiliary releases, spring charging motors, electronic trip units,
external current sensors, auxiliary circuit signaling switches, automatic reset devices, and
interlocks can all be exchanged or retrofitted at a later stage, thus allowing the circuit
breaker to be adapted to new, changing requirements.
