Allen Bradley 1492 1492-SPM MCB, 1P, 40A Curve C, 277V AC, 48V DC, 10 kA Breaking Capacity

Experience high performance and exceptional protection for electrical circuits with the general purpose 1492-SPM Type C Miniature Circuit Breakers by Allen Bradley.

These 1492-SPM MCB’s have type C tripping and fast breaking time to provide a higher level of safety for your application. They include screw terminals, are IP20 finger safe, and can be DIN rail mounted for optimal convenience. They are current-limiting and are available in 1, 2 or 3 pole versions, offering more versatility to meet your requirements. They also have dual terminals for wiring and bus bar flexibility. These units have excellent shock and vibration resistance which helps to prevent nuisance tripping, avoiding unnecessary downtime. Up to six accessories can be installed on the same circuit breaker to enable easy optimisation of your safety system.

Type C MCB’s are suitable for use in commercial and light industrial applications, such as fluorescent lighting and small electric motors, and are designed to trip at currents between five and ten times their rated load.

• Available in 1, 2 or 3 pole versions to suit your application needs
• DIN Rail mountable in any position to ensure easy installation
• Dependable protection for circuits due to instantaneous break time
• Indicator window allows clear visibility of contact state: red for closed, green for open
• Screw Terminals
• Thermal-magnetic tripping mechanism
• Can be used in extreme ambient conditions
• RohS compliant and fully recyclable, offering a more environmentally friendly solution

Protect your electric equipment from current overload by using this MCB from Rockwell Automation's Allen Bradley range. It features a thermal-magnetic tripping mechanism, which breaks the electrical circuit when the power supply exceeds a current level over 10kA. A front-facing toggle switch lets you reset the unit quickly when a fault has been cleared, reducing downtime. As it's a type C MCB, this breaker trips when it receives between 5 and 10 times its rated current of 40A. This makes it suitable for applications like lighting fixtures, where current surges are common on startup.

• Resistance to shock and vibration helps prevent false tripping
• IP20 rating indicates user's fingers are protected from electric shock
• Mechanical lifetime of 20,000 operations for lasting use
• Ambient operating temperature range between -25°C and +55°C to withstand demanding environments

• UL Recognised
• CSA C22.2 No. 235
• EN 60947-2
• CE Marked
• VDE Certified

You can mount this MCB by simply clipping it to a DIN rail, so there's no need for any specialist tools.
