The 1492-SPM Type B general purpose Miniature Circuit Breakers by Allen Bradley offer excellent protection for electrical circuits. With this series 1, 2, and 3 Pole units are available so that you can find the perfect MCB to suit your application.

The 1492-SPM series of MCB’s are current limiting and have an instantaneous break time. These models have Type B Tripping characteristics. They are IP20 finger-safe and they also have dual terminals for wiring and bus bar flexibility. Installation is simple as these MCB’s can be DIN rail mounted, and up to six accessories can be fixed on the same circuit breaker to provide a complete electrical safety system. The 1492-SPM series of circuit breakers reduces downtime from nuisance tripping due to their enhanced shock and vibration resistance.

A Type B miniature circuit breaker will trip instantly at a rate of three to five times its rated current. These MCB’s are often used for small inductive loads where switching surges are very low. They are frequently used in residential or light commercial applications.

Protect your electrical components with this highly sensitive mini circuit breaker (MCB) from Rockwell Automation's Allen Bradley range. This device works by cutting off power to your equipment when a short circuit or overcurrent occurs, preventing potential harm to operators and damage to equipment. It has dual connection terminals, so you can link it to your system by either wiring or bus bar, giving you the flexibility of choice. You'll find it useful in light-duty applications with small inductive loads.

• IP20 (ingress protection) rated to withstand dust and objects larger than 12mm in size
• Breaking capacity of 10kA for strong resistance to current surges
• Electrical service life of 6,000 operations to ensure long term performance
• Broad operating temperature range of -40°C to +70°C for use in harsh environments

• CE (Conformitè Europëenne)
• CCC (China Compulsory Certificate)
• VDE (Verband Deutscher Elektrotechniker)
• RoHS (Restriction of Hazardous Substances

You should schedule maintenance for this component every one to three years, depending on its operating conditions. You should also check it if you notice it's tripping out or close to its rated current.
