Allen Bradley 1492 SP Series Miniature Circuit Breakers – Type D
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.

Allen Bradley Mini Circuit Breaker, 10kA Breaking Capacity, 4A Current Rating - 1492-SPM1D040
This 1-pole miniature circuit breaker (MCB) from Rockwell Automation's Allen Bradley range provides high-performance electrical circuit protection. It immediately trips the power supply when earth leakages or short circuits are detected, to prevent electrical shocks and safeguard equipment from damage. The MCB has a Type-D tripping curve, meaning it will trip currents 10 to 25 times its own 4A (ampere) rating for excellent reliability. Use this product on high-inductive-load equipment like medical imaging devices and large winding motors.
• Calibration temperature of +40?C for use in extreme ambient conditions such as industrial kitchens and workshops• Status indicator window clearly shows whether the MCB is open or closed
Standards and Certifications
• UL (Underwriters' Laboratories)• CSA (Canadian Standards Association)• CE (Conformité Européenne)• CCC (China Compulsory Certificate)• VDE (Verband der Elektrotechnik)• RoHS (Restriction of Hazardous Substances)
How long do MCBs last?
The Consumer Product Safety Commission (CPSC) rated the lifespan of MCBs between 30 and 40 years. This Allen Bradley MCB complies with all crucial standards and carries certifications to assure you of its excellent quality.
