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.

With an instant breaking time, this miniature circuit breaker (MCB) from Rockwell Automation's Allen Bradley range prevents overcurrent from damaging your equipment. It's suitable for industrial and commercial use to safeguard valuable hardware like X-ray machines and welding kit. A quick visual inspection of the component's red/green indicator window lets you know if the contacts are open or closed. Its dual terminals clamp from both sides, giving it superior connection reliability in harsh conditions. You can use this MCB in hot or cold settings, thanks to its wide operating temperature range of -25°C to +55°C.

• Resists vibration and impact to help prevent nuisance tripping and unnecessary downtime
• Designed to direct conductors into terminal openings for easier wiring
• Quick-snap feature allows for rapid and tool-free DIN rail assembly
• Fully recyclable for a reduced carbon footprint

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

This MCB has screw terminals that clamp down firmly on wires. All you need to attach conductors and achieve a reliable electrical connection is a number 2 Pozidrive screwdriver.
