Allen-Bradley 1492-SP3D100 is a three-pole miniature circuit breaker (supplementary protector) from the 1492-SP family, delivering thermal‑magnetic protection with a D‑trip characteristic for overloads and short circuits. It is rated for 10 A and designed for three‑phase AC circuits up to 480 V, with no neutral pole (3P, without N). This model is intended for installation in industrial control panels to safeguard motors, relays, and other 3‑phase equipment, providing fast interruption and predictable trip performance within Allen‑Bradley automation systems.
