Allen-Bradley 1492-SP3D100 Three-Phase Circuit Breaker

Allen-Bradley 1492-SP3D100 is a three-pole, 10-amp circuit breaker rated for 415 VAC, designed for three-phase protection in industrial electrical panels. It interrupts current to protect downstream equipment in three-phase distributions, with a compact form factor suitable for panel mounting. The 1492-SP3D100 is part of Allen-Bradley’s 1492 family of protective devices, delivering reliable protection for motors, feeders, and other three-phase loads in industrial environments. Typical applications include motor feeders, three-phase power distribution circuits, and control panels in manufacturing and process facilities. The 10 A current rating and 415 VAC voltage rating define the operating envelope, enabling safe interruption of fault currents within those limits.
