1492-SPM3D320, Allen Bradley 1492 1492-SPM MCB, 3P, 32A Curve D, 277V AC, 10 kA Breaking Capacity

Allen Bradley 1492 SP Series Miniature Circuit Breakers – Type D

Safeguard your electrical circuits with the general purpose 1492-SPM Type D Miniature Circuit Breakers by Allen Bradley. These circuit breakers offer high performance and ensure enhanced protection for equipment.

These MCB’s have instantaneous breaking time and feature type D tripping. They are available in 1, 2 and 3 pole versions to suit your application. The 1492-SPM miniature circuit breakers are current limiting and can be easily mounted on a DIN rail. These units are also IP20 finger-safe for greater protection, and they have dual terminals for wiring and bus bar flexibility. These dependable MCB’s help to prevent downtime from nuisance tripping as they also have superior shock and vibration resistance. The 1492-SPM series allows installation of up to six accessories on the same circuit breaker so that you can optimise your safety system with ease.

Type D MCB’s are usually used for specific industrial and commercial applications with very high inductive loads and where high inrush current frequently occurs, for example with x-ray machines, large winding motors, transformers, and welding equipment. A type D MCB will trip instantly at a rate of ten to twenty-five times its rated current.

Allen Bradley Miniature Circuit Breaker, 10kA Breaking Capacity, 32A Current Rating - 1492-SPM3D320

Use this 3-pole circuit breaker from Rockwell Automation’s Allen Bradley range to safeguard your electrical equipment from overcurrent or abnormal conditions. It’s designed to immediately switch off a circuit when an electrical fault is detected, protecting you and your equipment from injury or damage. The unit has a thermal-magnetic tripping mechanism, which causes instantaneous circuit breaking when heat changes are detected in your system. Thanks to its toggle switch actuator, you can manually reset this breaker or turn it off for maintenance and repair.

• IP20 (ingress protection) rating indicates a finger-proof design with protection against dust particles
• Fitted with a red/green indicator window for system status monitoring
• Maximum voltage rating of 480V AC for use in high-energy systems
• Compact dimensions of 75 (W) x 53 (L) x 88mm (D) to fit in tight spaces

Standards and Certifications

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

How do I mount this circuit breaker?

You can easily install this circuit breaker on a DIN rail using its fast clip. Screw terminals are on hand to ensure reliable wire connections are made using only a number 2 Pozidrive screwdriver.
