What is BS EN 60669-2-3 - Time delay switches for household and electrical installations about?
BS EN 60669-2-3 is a British standard as a part of the IEC 60669 series that applies to time-delay switches (hereinafter referred to as TDS) with a rated voltage not exceeding 440 V and a rated current not exceeding 63 A, intended for household and similar fixed electrical installations, either indoors or outdoors, operated by hand and/or by remote control. TDS are provided with a time-delay device operated by mechanical, thermal, pneumatic, hydraulic, or electrical means or by a combination of them.
Electronic TDS are within the scope of IEC 60669-2-1. TDS including only passive components such as resistors, capacitors, PTC and NTC components, and printed wiring boards are not considered to be electronic TDS.
