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.

Protect your electrical circuits with this 1-pole miniature circuit breaker (MCB) from Rockwell Automation's Allen Bradley range. This high-performance safety device automatically cuts the power supply when faults are detected to reduce the risk of electrical shocks and fire. As a Type-D unit, this MCB will trip instantly at a rate of between 10 to 25 times its 1A (ampere) current rating, making it suitable for industrial and commercial applications. Confidently use this item with very high-inductive load equipment like x-ray machines, uninterruptible power supply (UPS) systems and transformers.

• High impact resistance prevents nuisance power cuts leading to production downtimes• DIN rail mounting for fast, easy and space-saving installation• Thermal-magnetic tripping mechanism ensures immediate electricity supply cuts to reduce risks of injuries to workers and damage to equipment

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

Yes. This essential safety device has a calibration temperature of +40˚C and can withstand jolts and shocks without sustaining damage.
