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 Miniature Circuit Breaker, Type D, 3A Current Rating - 1492-SPM1D030

Shield your equipment from short circuits with this miniature circuit breaker from Rockwell Automation's Allen Bradley range. It features a type D curve, so trips at currents between ten and twenty-five times its 3A rating. You'll find it used with very high inductive loads such as those found in x-ray machines and UPS (uninterruptible power supply) systems. The unit's dual-wire terminals can be wired either way round to suit the needs of your setup. This unit has an operating temperature range between -40°C and +70°C, so is suitable for use in demanding environments.

Features & Benefits

• Combinable with up to six auxiliary elements for a more rigorous safety setup
• Screw terminals keep the device tightly secured against nuisance tripping from impact shocks or vibration
• Mountable in any position for versatile installation
• Mechanical lifespan of around 20,000 cycles for long-lasting use

Standards and Certifications

• UL (Underwriters' Laboratories)
• CSA (Canadian Standards Association)
• CE (Conformitè Europëenne)
• VDE (Verband der Elektrotechnik)

How do I see the contact state of this miniature circuit breaker?

The MCB's switch will be in the upward-facing position and a green bar will show when it's open. The switch will face down and a red bar will show when the switch is tripped.
