Challenger CBB2030 Bolt On 2 Pole Circuit Breaker

Challenger CBB2030 is a bolt-on, two-pole molded‑case circuit breaker from the Challenger CBB series, rated for 30 A at 120/240 VAC in a 1‑phase system. It features a thermal‑magnetic trip mechanism with separate long-time and instantaneous trip functions and offers a 10,000 A interrupt rating at 240 V, enabling rapid disconnection on overloads or short circuits. The bolt‑on mounting and compact molded‑case construction are designed for use in Challenger panelboards and other bolt‑on compatible enclosures, where it protects feeders and individual branch circuits in residential and light commercial distributions. With its Type CBB designation, this device belongs to Challenger’s established CBB lineup, providing a reliable, compatible option for 2P 120/240 V circuits in environments that require straightforward replacement or upgrade of existing bolt-on breakers. Typical applications include protecting 240 V multi‑wire branch circuits, HVAC feeders, water heater circuits, and other common 120/240 V loads served from standard panelboards.
