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.

• Easy and fast installation via DIN rail mounting

Protect your electrical systems with this highly sensitive miniature circuit breaker (MCB) from Rockwell Automation's Allen Bradley range. It shields your system from the hazards of short circuits and overcurrents by instantly cutting the power supply when a fault occurs and only resetting when it's cleared. Thanks to clear red and green indicators on its toggle switch, it's easy to see when the unit is off or on, making diagnosis simple and reducing downtime. This device has a current rating of 10A and it's designed for use with small inductive loads with minimal switching current surges.

• Enhanced shock and vibration resistance to eliminate false tripping
• IP20 (ingress protection) rated to withstand dust and objects larger than 12mm in size
• Type-B characteristics to trip when it receives three to five times its rated current for high sensitivity
• Dual terminals to accommodate wire and bus bar connections for versatility

• UL (Underwriters' Laboratory)
• CSA (Canadian Standards Association)
• CE (Conformitè Europëenne)

The breaking capacity of this MCB is the maximum current that it can interrupt without being destroyed or arcing. This MCB's breaking capacity is 10kA (kiloamperes).
