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.

Are high inrush currents a concern in your electrical installation? This miniature circuit breaker from Rockwell Automation's Allen Bradley range uses a thermal-magnetic tripping mechanism to detect overloads and switch currents off before damage occurs. A bi-metal strip heats up in over-current conditions and bends out of contact, breaking the circuit instantaneously. Thanks to a type D curve, the MCB trips at currents between ten and thirty times its rated load of 2A. It's used with high inductive loads with frequent inrushes, such as industrial welding equipment and large winding motors.

• Mechanical lifespan of around 20,000 operations for reliable long-lasting use
• Indicator window makes it simple to identify the unit's state – red when closed and green when open
• IP20 (ingress protection) rating indicates a finger-safe unit that protects users against electric shocks
• Pairs with up to six auxiliary elements to add further protection to your equipment

• CE (Conformitè Europëenne)
• UL (Underwriters' Laboratories)
• CSA (Canadian Standards Association)
• VDE (Verband der Elektrotechnik)

The MCB clips securely into place on a DIN rail, making installation quick and simple.
