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.

Looking for a high-performance solution to detect faults on your electrical circuits? This 3A (ampere) miniature circuit breaker (MCB) from Rockwell Automation's Allen Bradley range is an essential safety device. It immediately trips the power whenever there are problems like earth leakages or short circuits. The thermal-magnetic tripping mechanism ensures instantaneous breaking to help prevent serious injuries like fatal shocks as well as the risk of damage to valuable equipment. As a Type-D unit, this MCB can be used with industrial equipment experiencing high inductive loads and inrush currents.

• Excellent impact resistance to avoid nuisance tripping and unnecessary downtime• DIN rail mounting for fast and easy mounting in tight spaces• Clearly visible status indicator shows whether contacts are open or closed to prevent accidents

• UL (Underwriters' Laboratories)• CSA (Canadian Standards Association)• CE (Conformité Européenne)• CCC (China Compulsory Certificate)• VDE (Verband der Elektrotechnik)• RoHS (Restriction of Hazardous Substances)

Yes. A thermal-magnetic circuit breaker combines thermal and magnetic tripping efficiency. This combination allows the MCB to avoid nuisance tripping, while responding immediately to faulty high currents.
