Overview
The Siemens B2020 is a 20-amp 2-in-1 Single-Pole Tandem Circuit Breaker designed for use with Siemens BL and BW series load centers, providing reliable overcurrent protection across two circuits in the space
of one.
Tandem breakers are ideal for load centers that are full but require additional circuit capacity, allowing two 120V branch circuits to fit in a single breaker slot. The thermal-magnetic trip mechanism
protects against both overload and short-circuit conditions, disconnecting each circuit independently when a fault is detected.
