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.

• Easy and fast installation via DIN rail mounting
• Instantaneous break time
• Available in 1, 2 or 3 pole versions
• Thermal-magnetic tripping mechanism
• Clear visibility of contact state due to indicator window: red for closed, green for open
• Environmentally friendly - RohS compliant and fully recyclable

Looking for a reliable circuit protection tool for your electrical systems? Choose this mini circuit breaker (MCB) from Rockwell Automation's Allen Bradley range. The unit has type-B characteristics, which means it'll trip instantly when it receives three to five times its rated current. This protects your circuits from current overloads that could harm both operators and equipment. For safety from electric shocks, the MCB's terminals are located out of reach, so you don't have physical contact with them. You'll find components like this one used in electrical and automation applications handling small loads.

• Dual terminals for wiring and bus bar flexibility
• Fully recyclable for environmental sustainability
• Can accommodate up to six devices to deliver complete circuit protection
• Compact dimensions of 88 (D) x 69 (W) x 17.5mm (L) for use in small enclosures

• CSA (Canadian Standards Association)
• VDE (Verband Deutscher Elektrotechniker)
• RoHS (Restriction of Hazardous Substances)

The main difference between a circuit breaker and a fuse is that a fuse is a sacrificial device, while a circuit breaker isn't. You need to replace a fuse once it's tripped but a circuit breaker can be reset.
