ABB SN201 MCB, 1P+N, 20A Curve C, 230V AC, 4.5 kA Breaking Capacity

Your devices are in safe hands with this MCB from ABB. Thanks to thermal and magnetic tripping mechanisms, it protects against overloads and short circuits, so the risks of electrical damage are shut down. It has a 1P+N configuration, enabling you to disconnect the live and neutral wire in the event of a fault. You'll find this handy in TN and IT wiring systems where long cable lengths are common. This compact module has a width of 18mm, making it easy to fit inside consumer units and final distribution boards in homes and businesses.

• Holder on front for labelling circuits
• Top and bottom clips for secure mounting
• Large terminal hole gives insulated screwdrivers room to manoeuvre
• Modular style means you can combine it with devices such as an under-voltage trip (225-6150)

• Retail units
• Residential buildings
• Office blocks
• Low-voltage machines

A device like this one with a C-type trip opens the circuit instantly when it detects currents between 5 and 10 times the rated load, so they're useful for circuits carrying inductive loads, such as motors and lights.
