Challenger CD3225 is a 3‑pole, 225 A, 240 V AC molded‑case circuit breaker from the CD series, designed for industrial panel protection. This bolt‑on unit uses a thermal‑magnetic trip mechanism to provide reliable overload and short‑circuit protection, with an interrupting rating of 10 kA at 240 V. It is intended for protecting feeders and branch circuits in commercial or light‑industrial electrical distributions where a 225 A, 240 V protective device is required.
