Need a compact way to shield your devices from electrical hazards? Go for this MCB from ABB. A dual-pole configuration means it controls two circuits simultaneously and reduces the wiring needed in your system. It has type-K tripping characteristics, meaning it breaks when the supply current is 8 to 12 times its 20A current rating, so it's suitable for high-power electrical setups. An IP40 rating applies when the unit's installed in a closed enclosure, indicating that it’s safe to touch and protected from tools and wires larger than 1mm.

• Screw terminals for convenient installation with a screwdriver
• Mechanical endurance of 20,000 cycles for long-lasting service
• Compact dimensions of 69 (L) x 35 (W) x 88mm (H) mean it slots easily into smaller enclosures
• Performs reliably in demanding conditions, thanks to an operating temperature range between -25°C and +55°C
• Low power loss of 5.4W for energy efficiency

• Mining equipment
• Maritime and offshore facilities
• Construction sites
