Allen Bradley 1492 1492-SPM MCB, 1P, 10A Curve D, 277V AC, 48V DC, 10 kA Breaking Capacity

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.

Looking for a reliable device to protect your equipment from electrical malfunction? Choose this MCB (miniature circuit breaker) from Rockwell Automation's Allen Bradley range. In the event of a current overload or short circuit, it cuts off power to the circuit, preventing potential damage. An instantaneous break time means you can rely on it for a quick response. Thanks to its breaking capacity of 10kA, this MCB is suitable for commercial use. For added durability, it's resistant to shock and vibration to prevent false tripping in demanding environments.

• DIN rail mounting for quick, tool-free installation
• Indicator window shows operating status for quick diagnosis
• Mechanical endurance of 20,000 operations for long-term use
• IP20 (ingress protection) rated so resists damage from solid objects sized up to 12mm

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

Type D miniature circuit breakers will trip if they detect between 10 and 20 times their maximum load current passing through the circuit. They're typically used in applications with high inductive loads.
