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, 8A Current Rating - 1492-SPM1D080

Use this miniature circuit breaker (MCB) from Rockwell Automation's Allen Bradley range to shield your industrial equipment from current overload and short circuits. It automatically cuts off power to the circuit when an abnormal current occurs – type D tripping characteristic means it'll trip if it detects surges between 10 and 20 times its standard current supply. Thanks to a broad operating temperature range of -25°C to +55°C, this unit can withstand demanding industrial environments. You'll find MCBs like this effective for protecting heavy-duty kit like welding equipment.

• Dual terminals accommodate both wiring and bus bars for versatility
• Toggle switch for easy manual reset
• Instantaneous break time for responsive operation
• Resistant to shocks and vibration to prevent false tripping
• Indicator window for easy status monitoring

Standards and Certifications

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

How do I mount this MCB?

You can mount this device by simply clipping it onto a DIN rail without the need for specialist tools. As it can be mounted in any position, you can adapt it to your existing setup with ease.
