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

Provide reliable protection for your electrical systems with this high-performance mini circuit breaker (MCB) from Rockwell Automation's Allen Bradley range. The unit works by cutting off the power supply to your equipment when an electrical fault occurs and only restoring it when the error is resolved. As it comes in a thermoplastic housing, this is a durable and impact-resistant choice for use in harsh environments. For easy diagnosis of an issue, it has clear red and green indicators to show you when it's off or on. MCBs like this one are designed for general purpose use in electrical circuits.

• Light weight of 115g, so it's easy to handle and won't put strain on your equipment
• Easy DIN rail mounting saves time and effort
• Wide operating temperature range of -40°C to +70°C for use in harsh environments

• UL (Underwriters' Laboratory)
• CSA (Canadian Standards Association)
• CE (Conformitè Europëenne)
• CCC (China Compulsory Certificate)
• VDE (Verband Deutscher Elektrotechniker)
• RoHS (Restriction of Hazardous Substances)

No, it doesn't. It's designed to trip when a fault occurs and should be manually reset when the error has been cleared.
