To get the better of current leakage across your system, reach for this RCCB from ABB. Its four protective poles keep a keen eye out for electrical faults over up to four circuits at once, so it's a space-efficient option. By tripping when it detects residual current over 30mA, the unit stamps out leaks before they become hazardous to you and your setup. A built-in test button lets you know everything's working as intended, so you can focus on other business. There's no need to worry about current leakage spikes, as the breaker trips instantaneously to put a halt on sudden faults.

• Low power loss of 5.3W per pole, so you get energy-efficient fault detection
• Lasts for 10,000 electrical operations for a long service life
• Mounts on a DIN rail, ensuring quick tool-free installation
• Slim body measurements of 70 (W) x 85 (H) x 69mm (D) to easily pack onto busy rails

• Retail industry
• Server management
• Manufacturing facilities

You can reset this unit easily with a quick flip of its front-mounted toggle switch.
