The 1492-SPM Type B general purpose Miniature Circuit Breakers by Allen Bradley offer excellent protection for electrical circuits. With this series 1, 2, and 3 Pole units are available so that you can find the perfect MCB to suit your application.

The 1492-SPM series of MCB’s are current limiting and have an instantaneous break time. These models have Type B Tripping characteristics. They are IP20 finger-safe and they also have dual terminals for wiring and bus bar flexibility. Installation is simple as these MCB’s can be DIN rail mounted, and up to six accessories can be fixed on the same circuit breaker to provide a complete electrical safety system. The 1492-SPM series of circuit breakers reduces downtime from nuisance tripping due to their enhanced shock and vibration resistance.

A Type B miniature circuit breaker will trip instantly at a rate of three to five times its rated current. These MCB’s are often used for small inductive loads where switching surges are very low. They are frequently used in residential or light commercial applications.

Protect your electrical equipment with this sensitive mini circuit breaker (MCB) from Rockwell Automation's Allen Bradley range. It detects overcurrents and cuts off the power supply to the circuit before they can cause damage to your equipment. The MCB has an instantaneous break time, which means it reacts immediately to the slightest change in state, for optimal electrical safety. It's a 2-pole device so you can use it to control two circuits. This reduces the amount of wiring and space needed for your setup. With a voltage rating of 277V, this component is a good fit for low-voltage applications like home-office equipment.

• Easy and fast installation via DIN rail mounting• Clear sight of contact state thanks to indicator window – red for closed, green for open• Screw terminals eliminate the need for complex tools when installing• Shock and vibration resistance to reduce downtime from nuisance tripping

• Underwriters' Laboratory (UL)• Canadian Standards Association (CSA)

This component has an IP20 (ingress protection) rating, so it's able to withstand dust and objects more than 12mm in size. That means it's considered finger-safe.
