Fire prevention using elevated glow-wire ratings

September 11, 2015 // By Julien Happich
When it comes to household appliances used in unattended operation, the provisions of standard IEC 60335-1 have placed higher requirements regarding glow-wire ignition temperature (GWIT).

These more stringent requirements thus also apply to installed components such as power sockets, fuse holders and connectors. For this reason, all components carrying current must meet the requirements of glow-wire tests as specified in IEC 60695-2-12 and -13.

In its FPG series of shock-safe fuse holders, manufacturer Schurter offers a wide range of shapes and sizes as well as fuse blocks for assembly on circuit boards. Power connectors rated for 10 A and 16 A, including with a wide range of assembly types and various terminals, also meet these stricter requirements.

The components fulfil and exceeds the strict guidelines concerning fire prevention for electrical devices that are operated in households unattended (as described in standard IEC 60335-2). Examples of such appliance types are dishwashers, coffee machines, washing machines and kitchen stoves.
