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.

Use this miniature circuit breaker (MCB) from Rockwell Automation's Allen Bradley range to protect your industrial machinery against overcurrent. It breaks a circuit instantly if a fault occurs, so prevents damage to downstream equipment. The MCB includes a red/green indicator window that allows you to quickly determine its contact state. It's designed to help you guide conductors during wiring, which makes termination easier and faster. Installation is tool-free and quick thanks to its snap-on DIN rail mounting feet.

• Dual terminals clamp from both sides to make reliable connections
• IP20 (ingress protection) rated enclosure that's finger-proof and protected against objects larger than 12mm
• Toggle switch allows for quick manual resetting
• Environmentally friendly product that's fully recyclable

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

Yes, this MBC is insulated, which means it's not negatively affected by nearby electronic components. Its insulation also reduces the risk of shocks to operators during installation and handling.

Yes, this MCB resists shocks and vibration, so it's suitable for use in harsh industrial environments.
