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 equipment from current overload using this miniature circuit breaker (MCB) from Rockwell Automation's Allen Bradley range. It has dual connection terminals so you can set it up with wires or bus bars, making it a versatile choice. A toggle switch lets you easily reset it to its original state. As it's a type D MCB, it'll trip when it receives between 10 and 20 times its recommended current rating. This makes it suitable for powerful industrial applications like large motors and power generating systems.

• Mechanical service life of 20,000 operations for durability
• DIN rail mounting for time-saving installation
• Broad operating temperature range of -25°C to +55°C for use in demanding environments
• IP20 (ingress protection) rating indicates it's touch-proof to prevent risk of electric shocks

• UL (Underwriters' Laboratories)
• CSA (Canadian Standards Association)
• CE (Conformitè Europëenne)
• CCC (China Compulsory Certificate)
• VDE (Verband Deutscher Elektrotechniker)
• RoHS (Restriction of Hazardous Substances)

The unit has an indicator window that shows its contact state in two colours – red stands for ON and green stands for OFF. This lets you know the operating status of the device at a glance, for easy diagnosis.
