    Allen Bradley 1492 SP Series Miniature Circuit Breakers – Type D


    Safeguard your electrical circuits with the general purpose 1492-SPM Type D Miniature Circuit Breakers by Allen Bradley. These circuit breakers offer high performance and ensure enhanced protection for equipment.

    These MCB’s have instantaneous breaking time and feature type D tripping. They are available in 1, 2 and 3 pole versions to suit your application. The 1492-SPM miniature circuit breakers are current limiting and can be easily mounted on a DIN rail. These units are also IP20 finger-safe for greater protection, and they have dual terminals for wiring and bus bar flexibility. These dependable MCB’s help to prevent downtime from nuisance tripping as they also have superior shock and vibration resistance. The 1492-SPM series allows installation of up to six accessories on the same circuit breaker so that you can optimise your safety system with ease.

    Type D MCB’s are usually used for specific industrial and commercial applications with very high inductive loads and where high inrush current frequently occurs, for example with x-ray machines, large winding motors, transformers, and welding equipment. A type D MCB will trip instantly at a rate of ten to twenty-five times its rated current.

    Allen Bradley Miniature Circuit Breaker, 10kA Breaking Capacity, 50A Current Rating - 1492-SPM3D500


    Keep yourself and your system safe from overcurrent with this 3-pole circuit breaker from Rockwell Automation’s Allen Bradley range. It ensures a circuit is broken immediately in the event of an electrical fault or abnormality. The unit has a finger-safe design to reduce the risk of shocks during use. An IP20 (ingress protection) rating indicates it's secured against damage from dust and wires or tools over 12mm in size. You can easily clip this circuit breaker onto a DIN rail in a tight or awkward space thanks to its compact dimensions of 75 (W) x 53 (L) x 88mm (D).

    • Toggle switch allows for quick system resets and manual switching off for maintenance
    • Features a colour-changing red/green indicator window for system status monitoring
    • Maximum voltage rating of 480V AC for use in high-energy systems

    How does this circuit breaker work?


    This thermal-magnetic circuit breaker features an internal bimetal element that flexes in response to a temperature rise caused by overcurrent. By changing shape, it breaks the circuit and stops the flow of electricity.
