1492-SPM1B030, Allen Bradley 1492 1492-SPM MCB Mini Circuit Breaker, 1P, 3A Curve B, 277V AC, 48V DC, 15 kA Breaking Capacity

Allen Bradley 1492 SP Series Miniature Circuit Breakers – Type B

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.

Allen Bradley Mini Circuit Breaker, 10kA Breaking Capacity, 3A Current Rating - 1492-SPM1B030

This miniature circuit breaker (MCB) from Rockwell Automation's Allen Bradley range offers reliable protection from current overloads in electrical systems. It cuts power to the circuit in the event of an overload and doesn't reset until the fault is cleared. Installation of this device is quick and simple – just clip it onto your DIN rail without the need for specialist tools. Thanks to its current rating of 3A, this unit is suitable for light-duty applications with small inductive loads, so you'll find it used in residential and light commercial applications.

• Dual terminals for both wired and bus bar connection flexibility
• Mechanical service life of 20,000 operations for reliable long-term performance
• Wide operating temperature range of -40°C to +70°C for use in harsh environments
• Toggle switch reset actuator for fast and easy restart after a fault has been cleared

Standards and Certifications

• UL (Underwriters' Laboratory)
• CE (Conformitè Europëenne)
• CCC (China Compulsory Certificate)

How do I test this MCB?

You can test this MCB using a voltmeter or multimeter. A positive reading on the meter indicates that it's working. If you get a zero reading, that means that the MCB isn't working or is de-energised.
