1492-SPM2D020, Allen Bradley 1492 1492-SPM MCB, 2P, 2A Curve D, 277V AC, 96V DC, 10 kA Breaking Capacity

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 Mini Circuit Breaker, 10 kA Breaking Capacity, 2A Current Rating - 1492-SPM2D020

Optimise the safety of your electrical circuits with this reliable 2-pole miniature circuit breaker (MCB) from Rockwell Automation's Allen Bradley range. The unit's instantaneous breaking time immediately cuts off power when faults occur to prevent accidents like fatal shocks and damage to expensive equipment. Superior impact resistance reduces operational downtimes by preventing nuisance tripping that interrupts work processes. This high-performance MCB uses Type-D tripping, making it suitable for the very high inductive loads and inrush currents required by equipment like x-ray machines and transformers.

• IP20 (ingress protection) rating means the MCB is finger-safe• Calibration temperature of +40˚C for use in extreme ambient conditions• Status indicator clearly shoes whether contacts are open or closed to prevent accidents

Standards and Certifications

• UL (Underwriters' Laboratories)• CSA (Canadian Standards Association)• CE (Conformité Européenne)• CCC (China Compulsory Certificate)• VDE (Verband der Elektrotechnik)• RoHS (Restriction of Hazardous Substances)

Are MCBs better than fuses?

MCBs are often used in low-voltage electrical circuits because they're more reliable than fuses. This Allen Bradley MCB from Rockwell Automation is more sensitive than a fuse and can be reset, whereas fuses can only be used once.
