Specification for Automatic Change-Over Contactors for Emergency Lighting Systems
N BS 764
Annotation
Design and performance requirements for d.c. and single-phase a.c. double-pole change-over contactors for low-voltages up to 250 volts and a range of standard current ratings, which are used to provide the automatic transfer of current supplied to safety lights from the normal source to an alternative source when the normal source fails; reconnection is automatic when the normal supply conditions are restored.
Автоматический перевод:
Автоматические переключатели для систем аварийного освещения
Конструктивные требования и эксплуатационные требования для d.c. и однофазные a.c. двухполюсные переводные контакторы для низких напряжений до 250 вольт и диапазона стандартных текущих оценок, использующихся для обеспечения автоматической передачи тока, поставляемого безопасному свету от нормального источника до альтернативного источника, когда нормальный источник перестал работать; переключение является автоматическим, когда нормальные условия поставки восстанавливаются.
