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.

Choose this miniature circuit breaker (MCB) from Rockwell Automation's Allen Bradley range to safeguard machinery against electrical faults. It's suitable to use with equipment that needs a high inrush current and trips almost instantly when overcurrent occurs. The unit resists shock and vibration, which makes it suitable to use in harsh industrial applications. Screw terminals ensure wires remain firmly in place, reducing maintenance time. For greater reliability, this MCB is insulated, so its function isn't negatively affected by nearby electronic components.

• Versatile option as you can mount it in any position
• Quick snap-on DIN rail mounting for fast and tool-free assembly
• Designed to help prevent wiring misses for easier installation
• IP20 (ingress protection) rated enclosure that's protected against touch and objects larger than 12mm

• 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 a wide operating temperature range of -25°C to +55°C, which makes it a reliable choice in harsh industrial environments.

To save space in your setup, you can install up to six accessories on this versatile MCB.
