Allen Bradley 1492 1492-SPM MCB, 2P, 1A Curve D, 277V AC, 96V 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.

To reliably protect your electrical system from overcurrent and short circuits, use this miniature circuit breaker (MCB) from Rockwell Automation's Allen Bradley range. As it has two terminals, you can connect it to the circuit using bus bars or cables, making it a versatile choice. Thanks to its type D tripping characteristics, the device will trip if it receives between 10 and 20 times its maximum current rating. This makes it suitable for use in heavy-duty industrial applications like UPS (uninterruptible power supply) units and winding motors.

• Current rating of 1A for energy-efficient operation
• Highly sensitive thermal-magnetic tripping mechanism for quick response to current changes
• Screw terminal contact for secure connection to circuit
• Indicator window showing red or green for quick status diagnosis

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

As it has a broad operating temperature range of -25°C to +55°C, this MCB can be used safely in both hot and cold environments.
