Allen-Bradley 1492-CB3H070 Three-Phase Circuit Breaker

Allen-Bradley 1492-CB3H070 is a three‑pole molded‑case circuit breaker from the Bulletin 1492 family, designed as a manual motor controller and supplementary protector for industrial control panels. This 3‑pole unit is rated for 480Y/277 VAC, with a nominal current of 7 A and a short‑circuit current rating of 10 kA at 125 V, employing a thermal‑magnetic protection scheme with long‑time and instantaneous (H‑curve) trip characteristics for reliable shutdown during overloads and faults. It uses a feed‑through connection for three‑phase distribution and weighs roughly 0.85 lb, reflecting its compact footprint for use in small motors or control circuits. In practical terms, it provides integrated switching and protection in a single, compact package suitable for panel builders and electricians needing dependable 3‑phase overload protection with a defined H‑trip curve.
