The toggle handle of the Allen-Bradley 140G-H2C3-C40 circuit breaker doubles as its switching mechanism and status indicator. It leverages the reverse loop design to open its contacts. The contacts are surrounded by an arc chamber with components that draw the arc away from the contacts and quickly cool them when the circuit is opened. A maintenance mode is available on the 140G-H2C3-C40 molded case circuit breaker to allow for system testing and maintenance without having to de-energize or power off the circuit breaker. This is achieved through its manually adjustable DIP switch that gives the users access to a preset group of protection parameters. This unit is compatible with an extensive range of field-installed accessories for application-specific requirements.
