Allen Bradley 1492 SP Series Miniature Circuit Breakers – Type C

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.

Allen Bradley Miniature Circuit Breaker, Type C, 40A Current Rating - 1492-SPM3C400

Stop short circuits from damaging your electrical devices with this miniature circuit breaker from Rockwell Automation's Allen Bradley range. The 3-pole design accommodates 3-phase electrical systems like those typically found in electric motors. As it has a Type C curve, the unit trips when it experiences currents five to ten times its 40A rated load, making it suitable for appliances with high switching surges, such as fans and pumps. A thermal-magnetic tripping mechanism makes sure current overloads are tripped instantaneously to protect equipment and prevent downtime.

Features & Benefits

• Ingress protection rating of IP20 makes sure the switch is safe to touch without risk of shocks
• Can accommodate up to six auxiliary elements for an enhanced safety setup
• Lifespan of around 20,000 mechanical cycles to provide long-lasting use
• Clips securely onto a DIN rail to save you installation time

Standards and Certifications

• UL (Underwriters' Laboratories)
• CE (Conformitè Europëenne)
• CSA (Canadian Standards Association)
• VDE (Verband der Elektrotechnik)
