For the electrical protection of heavy-duty industrial systems, grab this MCB from ABB. It's a type-C device, so trips when it receives 5 to 10 times its 63A current rating. This stops downstream equipment from being hit by rogue overcurrent. The handy unit mounts directly onto a DIN rail, so it's a piece of cake to incorporate with your existing framework. Slimline dimensions of 69 (L) x 35 (W) x 88mm (H) and a bottom-fixing auxiliary contact mean it's easy to fit in setups where space is in short supply.

• 2-pole unit accommodates two circuits to simplify your layout
• Weight of only 250g puts minimal strain on an enclosure or panel
• Mechanical lifespan of 20,000 cycles for reliable performance
• IP20 rating means the housing shields against objects larger than 12.5mm, so it's safe to touch

• Industrial control systems
• Critical medical devices
• Telecommunications networks
• IT installations

Yes, the unit's toggle switch has clear ON/OFF tags and green/red colour coding so you know its status at a glance.
