Overview
The Siemens B240 is a 40-amp Double-Pole Circuit Breaker designed for use with Siemens BL and BW series load centers, providing reliable overcurrent protection across a two-pole configuration.
Double-pole breakers are ideal for 240V applications such as dryers, water heaters, and other large household appliances. The thermal-magnetic trip mechanism protects against both overload and short-circuit
conditions, with a common trip design that disconnects both poles simultaneously during a fault.
