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.

Need a fast-acting circuit breaker? Try this MCB from Rockwell Automation's Allen Bradley range. It reacts instantly to overvoltage, so it helps to prevent electrical faults from causing damage to your equipment. An electromechanical lifespan of up to 6,000 operations means you can rely on it for a long service life. For ease of use, you can mount the unit in any position to best suit your needs. As it's resistant to shock and vibration, it reduces the chance of nuisance tripping and downtime. This component is suitable to use in lighting systems and other applications with low inductive loads.

• Wide operating temperature range between -30°C and +70°C for compatibility with demanding settings
• Robust nylon housing resists corrosion for longevity in moist conditions
• IP20-rated enclosure, so it's protected against objects larger than 12mm, including fingers
• Snaps onto a DIN rail for quick and uncomplicated installation and removal
