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.

Need extra circuit protection for your industrial machinery? This miniature circuit breaker (MCB) from Rockwell Automation's Allen Bradley range instantly breaks a circuit when there's a power surge. It's suitable for applications where branch circuit protection is already provided or isn't needed and it's easy to mount on a DIN rail using the quick-snap feature. To give added protection to your equipment, this MCB reacts instantly to overcurrent, which prevents unnecessary damage. Nuisance tripping is avoided thanks to its resistance to shock and vibration for improved efficiency and productivity.

• Wide operating temperature range of -25°C to +155°C so suitable for demanding environments
• Compact size with space-saving dimensions of 53 (L) x 75 (W) x 88mm (D)
• Screw terminals hold wires firmly and reduce the need for regular retightening
• Toggle switch for quick and simple manual resetting after a trip

• UL (Underwriters' Laboratories)
• CSA (Canadian Standards Authority)
• CCC (Chinese Standards)
• CE (Conformitè Europëenne)
• VDE (Verband Deutscher Elektrotechniker)

An MCB like this one is commonly used for industrial and commercial applications with very high inductive loads and where high inrush current frequently occurs. Examples of this include X-ray machines and large winding motors.
