Need a robust solution to help protect your heavy-duty electrical equipment? This moulded case circuit breaker from ABB steps in to safeguard applications against short circuits and overloads by automatically tripping faulty feeds. The multi-pole device accommodates up to four circuits, letting you streamline your setup. Thanks to the front-facing terminals, linking it up between your power source and application is a doddle. This breaker measures just 205 (H) x 186 (W) x 103.5mm (D), so fit neatly into busy panels or distribution boxes.

• Tough plastic casing insulates live components to minimise the risk of shocks
• Electrical durability of 7,000 cycles for long-lasting performance
• 400A current rating means the device can handle high inrush currents
• 6.071kg weight for easy handling

How do I know if this MCCB moulded case circuit breaker is on or off?


A front-facing toggle switch clearly shows if the device is live or not – it's in the up position when ON and down position when OFF. This helps with troubleshooting and electrical safety.
