Siemens Q24020CT2U is a quadplex QT low-voltage molded-case circuit breaker that consolidates four switching poles into a single compact unit for protecting 120/240 V circuits in distribution panels and control cabinets. It is rated for a current range of 40 to 20 A and provides up to 10 kA interrupting capacity at 240 V, with a thermal-magnetic trip mechanism to respond to overloads and short circuits. As a member of the Siemens QT family, this quadplex breaker is designed for reliable, modular protection in multi-branch circuits in commercial or industrial electrical systems.
