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 MCBs 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 MCBs 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 MCBs 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.
Features and Benefits:
• Instantaneous break time
• Can be DIN rail mounted for fast and simple installation
• Available in 1, 2 or 3 pole versions to meet your requirements
• Clear visibility of contact state due to indicator window: red for closed, green for open

Allen Bradley MCB, 3.2W Power Loss Per Pole, Type D Tripping - 1492-SPM1D250
Use this MCB from Rockwell Automation's Allen Bradley series to stop electrical faults from damaging your system. With its 25A current rating, it handles large electrical loads safely. If the unit receives current at between 10 and 20 times this rated level, it will trip and protect downstream equipment from damage. For ease of use, there's a front-mounted toggle switch that resets the MCB after a fault, as well as an easy-to-read indicator window that shows red for 'on' and green for 'off'.
• Instantaneous break time for effective short-circuit protection
• Maximum breaking capacity of 10kA to withstand powerful electrical surges
• Dimensions of 17.5 (W) x 88 (H) x 74mm (D) for easy installation in small cabinets
• Broad operating temperature range between -25°C and +55°C for use in tough industrial conditions
