Over deze norm
Applies to contactors above 1000 V up to 12 000 V a.c. including those combined with relays for protection purposes. It deals with characteristics and behaviour with respect to normal and overload conditions, dielectric properties, and tests. Excluded are contactors forming part of metal-enclosed switchgear, contactors being able to provide short-circuit protection, and fuse-contactor combinations, which all have to meet additional requirements.
