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.

Keep your electrical system safe with this miniature circuit breaker (MCB) from Rockwell Automation's Allen Bradley range. It uses a thermal-magnetic tripping mechanism, which means an internal bimetallic strip heats up and bends if it detects a current surge, breaking the circuit and preventing damage to the system. Thanks to an instantaneous break time, the unit's highly sensitive and delivers a quick response to current changes. For versatility, the dual terminals let you connect it to the circuit by wiring or bus bars.

• Type D tripping characteristics to react at between 10 and 20 times its rated current
• Indicator window shows operating status for quick diagnosis
• IP20 (ingress protection) rated for finger-safe operation
• Toggle switch for quick resetting

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

Breaking capacity refers to the maximum current rating that a circuit breaker can disrupt without being damaged. This MCB has a breaking capacity of 10kA.
