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.

Protect your electrical circuit from short circuits and overloads with this MCB from Rockwell Automation's Allen Bradley range. It has type B tripping characteristics, meaning that it trips at 3 to 5 times its rated current of 4A, making it suitable for use with sensitive systems. A 4A-rated current means you can use it on low-current-consuming appliances. Thermoplastic housing provides resistance to mechanical impact, making this a practical choice for harsh environments.

• Mechanical endurance of 20,000 operations for long-term performance
• Wide operating temperature range of -25°C to +55°C for use in challenging conditions
• Compact dimensions of 75 (W) x 53 (L) x 88mm (D) makes it ideal for installation in enclosures with limited space
• Red and green indicators for easy identification of the contact position
• DIN rail mounting for fast and easy installation
