Westinghouse Electric HKB3200T Circuit Breaker

The Westinghouse HKB3200T is a 3-pole, 200 A industrial circuit breaker with a 600 V AC rating, designed for panel and switchgear mounting to deliver dependable overcurrent and short-circuit protection for three‑phase power circuits. In practice, it is installed in switchgear assemblies, motor control centers, commercial electrical panels, and other industrial power distribution systems where reliable fault interruption is critical for safety and uptime. The device uses a thermal-magnetic trip mechanism and is compatible with switchgear and motor control centers, making it suitable for power distribution and motor protection in manufacturing facilities, commercial infrastructure, and industrial automation. Common replacements include Eaton HKB3200T, Cutler-Hammer HKB3200T, and Westinghouse HKD3200F.
