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.

Safeguard your machinery against the harmful effects of overcurrent with this miniature circuit breaker (MCB) from Rockwell Automation's Allen Bradley range. The device snaps simply onto a DIN rail for quick and tool-free installation. Its instantaneous reaction to electrical surges helps prevent downtime and damage to equipment for improved workplace productivity. A compact size of 53 (L) x 75 (W) x 88mm (D) allows for maximum circuit board packing efficiency. You can mount accessories on the bottom of this MCB, which further saves on space.

• Resists vibration and impact, so is suitable for harsh operating environments
• Immune to nuisance tripping to avoid unnecessary downtime and improve efficiency
• Clear visibility of its contact state, thanks to an indicator window
• Dual terminals clip on either side to make a reliable connection

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

This is a type D MCB, which means it instantly trips at 10 to 20 times its rated current of 10A. Its fast reaction time is suitable for the protection of uninterrupted power supplies (UPS).
