The use of circuit breakers, fuses and RCDs greatly reduces the risk of fire.
BS 7671:2008 Amendment 3: 2015 introduced further requirements to minimise the spread of fire that may occur within a consumer unit.

This Arc fault detection device is a 1P+N, 40A

Features
Arc faults are a common cause of domestic and building electrical fires.
Electrical arcs can result from, to name just a few examples, damaged wires in a bedroom lamp, pinched leads and worn electrical insulation.
Arc temperatures can exceed 5500°C and may ignite fires when they come into contact with combustible materials.

An Arc Fault Detection Device (AFDD) detects fault-related electrical arcs and breaks the circuit.
At the same time it is tolerant to electrical arcs caused by the normal operation of electrical devices such as switches, brushed motors and the plugging and unplugging of devices.

In collaboration with a number of other manufactures, BEAMA have created a guide to Arc fault detection devices. Please see the attached pdf file.
