Allen Bradley 1492 1492-SPM MCB, 3P, 40A Curve D, 277V AC, 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.

Ensure workplace safety with this 3-pole circuit breaker from Rockwell Automation’s Allen Bradley range. To protect you and your equipment, it will immediately switch off a circuit if overcurrent or electrical faults occur. The breaker has a built-in indicator window for system monitoring, which changes from red to green depending on whether it's off or on. The maximum voltage rating of 480V AC makes it suitable for use with high-energy systems. You can easily install this circuit breaker to a DIN rail, without the need for tools, using its quick clips.

• High current rating of 40A for heavy-duty use
• Compact dimensions of 75 (W) x 53 (L) x 88mm (D) to use minimal space in your setup
• Thermal-magnetic tripping mechanism detects heat changes for fast circuit switch-off
