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.

This Allen Bradley miniature circuit breaker (MCB) from Rockwell Automation automatically cuts an electrical circuit when abnormal conditions occur. It prevents damage to equipment so you benefit from more uptime and productivity. The robust unit has a mechanical endurance of 20,000 operations for reliable service throughout its lifespan. Its indicator window lets you see if its contacts are open or closed, so you can make quick visual inspections. As this MCB reacts instantly to overcurrent faults, it improves user safety by reducing the risk of electric shocks.

• Resists shocks and vibration for longevity in harsh operating environments
• IP20 (ingress protection) rated enclosure is touch-proof and protected against objects larger than 12mm
• Fully recyclable for a reduced carbon footprint
• Fast clip technology so quick to attach to a DIN rail without tools

• UL (Underwriters' Laboratories)
• CSA (Canadian Standards Authority)
• CCC (Chinese Standards)
• CE (Conformitè Europëenne)
• VDE (Verband Deutscher Elektrotechniker)
• RoHS (Restriction of Hazardous Substances)

This MCB features a terminal design that helps to simplify wiring and prevent miswiring by directing conductors into the terminal openings.
