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.

For the protection of your electrical circuit, try this Allen Bradley MCB from Rockwell Automation. Its type B tripping characteristics make it suitable to use with resistive or slightly inductive loads and equipment, like transformers, power supplies and control instrumentation. The miniature breaker features a robust nylon housing that resists corrosion and wear, so it's suitable for use in demanding industrial settings. It's insensitive to shock and vibration, which helps to reduce the chance of nuisance tripping and unnecessary downtime. For easy installation and removal, this device quickly snaps on or off your DIN rail.

• Miniature size of 35 (L) x 75 (W) x 88mm (D) to maximise packing efficiency on your circuit board
• Indicator window, so you can clearly and conveniently see its contact state
• Minimal need for maintenance, thanks to screw terminals that hold wires securely
• IP20-rated housing that's finger-proof and protected against objects larger than 12mm
