Allen Bradley MCB, Type C Tripping, Screw Terminals - 1492-SPM1C500

Use this general-purpose MCB from Rockwell Automation's Allen Bradley range to protect your electronic devices from harmful current supply. To prevent damage to downstream equipment, it's designed to quickly cut power to attached circuits if it detects a current overload or short circuit. The unit is a type C MCB, which means it trips instantly when it detects loads between 5 and 10 times its full load current of 50A. You'll typically find it used with devices that are prone to current surges, such as electric motors.

• Indicator window for easy status monitoring

• Broad operating temperature range between -25°C and +55°C makes it suitable for use in challenging environments

• Dual terminals allow clamping from both sides of the unit, offering flexible wiring options

• Front-facing toggle switch enables quick and easy reset

• DIN rail mounting for quick installation

Standards and Certifications

• VDE-certified

• UL-recognised

• CSA C22.2 no. 235

• RoHS-compliant

• CE-marked

What's meant by breaking capacity?

Breaking capacity is the maximum current flow an MCB can interrupt without sustaining damage. This unit has a breaking capacity of 10kA, which will generally be enough for more powerful electric devices that often experience higher current surges.

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.

Features and Benefits:

• 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
