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 MCB, 3A Current Rating, Type D Tripping - 1492-SPM3D030

Need a device that protects your electrical circuits from power surges? Choose this MCB from Rockwell Automation's Allen Bradley range. As it has three poles, you can use it to protect up to three circuits at once. Its type D tripping characteristics mean it trips at above 10 to 20 times the rated current, so it's ideal for applications, such as motors or lighting systems, where high inrush currents are common. As the breaker snaps into place on a DIN rail, it's quick and simple to install.

• Mechanical lifespan of 20,000 operations for long-lasting performance
• Features a toggle switch for quick resetting to minimise downtime
• IP20 rating means it's finger-safe and protected against objects larger than 12mm
• Red/green colour-coded indicator window displays the operating status for ease of monitoring
• Wide operating temperature range of -25°C to +55°C for use in demanding environments

Standards and Certifications

• UL
• EN 60947-2
• CE

What size is this MCB?
