Allen Bradley 1492-SPM 1492-SPM Miniature Circuit Breaker, 3-Pole, 4 A, Type D, 480 V AC, 96 V DC, 15 kA Breaking

Use this MCB from Rockwell Automation's Allen Bradley range to prevent damage to your equipment caused by electrical surges. It trips at above 10 to 20 times the current rating of 4A for protection against high inrush currents. Once the MCB has tripped and the fault is cleared, you can easily reset it using the front toggle switch. For secure installation, simply snap this device onto a DIN rail – you can mount it in any position for versatility. A wide operating temperature range between -25°C and +55°C makes this a suitable option for use in harsh industrial environments.

• Compact dimensions of 88 (L) x 75 (W) x 53mm (H) for installation in tight spaces

• CE

This MCB has a robust mechanical endurance of 20,000 operations, so you can be sure it will last a long time.

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.
