Allen-Bradley 1492-SP2C100 Molded Case Circuit Breaker

Allen-Bradley 1492-SP2C100 is a 2‑pole, molded‑case circuit breaker from Bulletin 1492‑SP, designed as a supplementary protector for commercial and light‑industrial electrical systems. It provides thermal‑magnetic protection with a Type C trip curve, delivering long‑time and instantaneous trip functions, and a 10 A rating at up to 480 V AC. It carries a 10 kA short‑circuit rating at 480 V and uses line and load side lug terminals; the trip assembly is non‑interchangeable to ensure consistent protective characteristics. The unit supports feed‑through applications, enabling straightforward distribution from a protected source to downstream devices. This compact, ready‑to‑install device from the 1492‑SP family protects branch circuits and equipment within panels and enclosures where a supplementary protector is required alongside other protection elements in commercial or light‑industrial environments.
