Install this moulded case circuit breaker from ABB to keep your industrial kit safe from short circuits and overcurrents. It's a protective device that automatically trips the power when faults pop up in feeds. For versatility, you can use the unit with AC and DC sources. An electrical durability of 8,000 cycles means it delivers consistent performance in demanding applications. It also resists impact and vibration, assuring you it stays connected through thick and thin. As the MCCB measures just 130 (H) x 76.2 (W) x 70mm (D), it's a sure fit in crowded panels.

• 3-pole unit, so handles up to 3 circuits to streamline layouts
• Toggle switch indicates the ON/OFF position for convenient troubleshooting and improved electrical safety
• Light weight of 1.1kg puts little strain on machinery

• X-ray machines
• Telecommunications networks
• Automated control panels
• Aerospace technology

The breaker has a bimetallic strip that heats up and bends when excess current passes over it. This releases a latch that trips or opens the contacts and disconnects the power supply.
