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 MCB, 40A Current Rating, 3 Poles - 1492-SPM3B400

Improve the safety of your electrical circuits with this MCB from Rockwell Automation's Allen Bradley range. The current-limiting device trips the power when faults occur to protect downstream equipment. It has reliable resistance to shock, which reduces the risk of nuisance disconnections, even in vibrating conditions. As it has type B tripping characteristics, it trips at 3 to 5 times its 40A rating, ensuring instant breaking and reduced downtime. A front toggle switch clearly indicates contact positions for easy problem detection. Use this unit for residential and light commercial electrical installations.

• Thermal-magnetic tripping mechanism safeguards against overcurrent and short circuits
• DIN-rail mounting for quick and tool-free installation
• Screw terminals for secure attachment
• IP20 rating indicates the unit is touch-proof for safe handling

Standards and Certifications

• UL
• CSA
• CE
• CCC
• VDE

How much space does this MCB take up on a distribution board?

It takes up little space, thanks to its compact dimensions of 53 (L) x 75 (W) x 88mm (D). Plus, you can fit up to six accessories on the same circuit breaker for comprehensive electrical safety.
