What is BS EN IEC 62271-106 about?
BS EN IEC 62271-106 discusses standards for switchgear and controlgear. BS EN IEC 62271-106 applies to AC contactors and/or contactor-based controllers and motor starters designed for indoor installation and operation at frequencies up to and including 60 Hz on systems having voltages above 1 kV and up to and including 24 kV. BS EN IEC 62271-106 applies only to three-pole devices for use in three-phase systems, and single-pole devices for use in single-phase systems. It includes additional requirements for outdoor installations where the equipment is housed in an additional protective enclosure. BS EN IEC 62271-106 gives requirements for starters associated with separate short-circuit protective devices and controllers, contactors combined with short-circuit protective devices (SCPD). Note 1: BS EN IEC 62271-106 applies to the operating devices of contractors and to their auxiliary equipment Note 2: BS EN IEC 62271-106 includes- direct on-line starters, reversing starters, two direction starters, Reduced k V A (voltage) starters incudes- auto-transformers starters, rheostatic starters, reactor starte...
