Allen Bradley 1492 SP Series Miniature Circuit Breakers – Type B

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.

Allen Bradley Mini Circuit Breaker, 10kA Breaking Capacity, 2A Current Rating - 1492-SPM2B020

Increase the electrical safety of your equipment with Rockwell Automation's general-purpose Allen Bradley miniature circuit breaker (MCB). This safety device automatically breaks a circuit when an overload or fault occurs. With a breaking capacity of 10kA, the unit has a high threshold and withstands large surges without failure. Integrated light-emitting diode (LED) indicators help you quickly and easily spot whether the circuit is on or off. A rated alternating current (AC) voltage of 277V and current rating of 2A make this MCB a good fit for low-voltage applications.

• Thermal-magnetic tripping mechanism for fast response to overvoltage and short circuits• Toggle-switch reset actuator to quickly reactivate the circuit breaker after a fault• Compact dimensions of 88 (D) x 35 (L) x 75mm (W) for space efficiency• Impact and vibration resistance make it suitable for use in harsh environments

Standards and Certifications

• Restriction of Hazardous Substances (RoHS)• Canadian Standards Association (CSA)

What's the difference between a circuit breaker and a fuse?

A circuit breaker can be reset to restore current flow to the circuit when the fault is cleared. A fuse, on the other hand, is what's known as a 'sacrificial device', meaning it has to be replaced after a fault.
