Challenger CD3150W U Molded Case Circuit Breaker

Challenger CD3150W 150A, 240V, 3P Molded Case Circuit Breaker delivers reliable overcurrent protection for 3‑phase power distribution. This unit is part of Challenger’s CD family and is a Type CD molded‑case breaker rated for 240 VAC with a nominal current of 150 A and a 10 kA interrupting capacity at 240 V. It uses bolt‑on mounting for secure installation in compatible panels and enclosures. With three poles, the CD3150W interrupts all three phases simultaneously, providing coordinated protection for three‑phase feeders and branch circuits. The SKU is CD3150W, anchoring it within Challenger’s molded‑case lineup. The 10 kA interrupt rating at 240 V specifies the maximum fault current the device is designed to interrupt at that voltage, helping to limit damage in overload or short‑circuit conditions. This compact MCCB is suitable for panelboard and distribution applications where a 3P, 150 A device with a solid interrupt rating is required.
