Challenger CH3020 is a 20-amp, three-pole molded-case circuit breaker built for 480Y/277 Vac three‑phase systems and designed for use in Challenger CH panelboards and distribution equipment. This bolt‑on CH3020 protects three‑phase circuits and is rated for 480 VAC operation with a 14 kA interrupting capacity, and for 240 VAC operation with a 65 kAIC rating, making it suitable for a range of commercial and industrial distribution needs. The model is commonly used in installations that run on 277/480 V systems to protect feeders and branch circuits, ensuring reliable disconnection of all three phases when fault or overload conditions occur.
