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 boost the safety of equipment connected to an electrical circuit. This supplementary device has a thermal-magnetic mechanism to protect against overloads and short circuits. It has a type D tripping characteristic, so it breaks the circuit instantly when currents between 10 and 20 times higher than its rated current are detected. Use it in industrial and commercial applications where excessive loads and inrush currents are likely, such as circuits powering electric motors.

• Simple red and green indicator colours make it easy to read the unit's status
• Toggle switches to quickly reset and isolate circuits
• Contains minimal harmful substances and is fully recyclable to reduce environmental impact
• Screw terminals and DIN rail mounting for a straightforward and secure installation

• UL (Underwriters' Laboratories)
• CSA (Canadian Standards Association)
• CE (Conformitè Europëenne)
• CCC (China Compulsory Certificate)

A 3-pole MCB is used to protect three circuits. It will break all three of the circuits if a fault is found on any one of them.
