This type-B MCB from ABB has a breaking capacity of 10kA and trips between three and five times its 6A full-load current. It's well-suited to residential and commercial applications, where it helps protect equipment like lighting against short circuits and current overload. The unit reacts almost instantly to a fault, which means there's minimal risk of power spikes causing damage to downstream appliances. Compact dimensions of 88 (L) x 17.5 (W) x 76mm (D) make this a space-saving component that supports efficient circuit-board packing.

• Clips onto a DIN rail for time saving and tool-free installation
• Suitable for use in demanding locations, thanks to a wide operating temperature range between -25°C and +55°C
• Compatible with both AC and DC input voltage to best suit your application's needs
• Low power loss of 2W makes it energy-efficient
• Contact position indicator tells you the unit's operating status

• Retail centres
• Hotels and restaurants
