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.

Prevent short circuits in your electrical supply with this miniature circuit breaker (MCB) from Rockwell Automation's Allen Bradley range. Its 10kA breaking capacity makes it suitable for heavy-duty applications. To make installation quick and simple, it attaches to a DIN rail with a single clip. As a type B breaker, it trips when the current is three to five times the rated current. MCBs like this one are frequently used in residential and light commercial installations.

• Mechanical endurance of 20,000 operations provides long-term performance and low maintenance
• IP20 (ingress protection) rating indicates the device is touch-proof and resistant to dust or objects greater than 12mm in size

• UL (Underwriters' Laboratories)
• CSA (Canadian Standards Association)
• CE (Conformitè Europëenne)
• VDE (Verband der Elektrotechnik)

The switch on this miniature circuit breaker will be in the upward-facing position when on and facing down when the switch is tripped. There's an additional indicator window for extra clarity, showing a red bar when on and a green bar when off.
