The SIWOC1 series mechanical emergency pump starting device is a contactor-based mechanical emergency pump starting product designed and developed for the fire water supply system. It has a manual strong start function and can meet the relevant requirements of the manual mechanical closing water pump function in Chapter 11 Control and Operation of GB 50974-2014 "Technical Specification for Fire Water Supply and Hydrant Systems". When the fire linkage or automatic control fails (malfunctions), By manually and locally forcing the start of the water pump by personnel, it ensures the normal operation of the fire pump in emergency situations and protects the safety of personnel's lives and property.
The product is suitable for starting, stopping, and related control of motors with AC 50Hz (or 60Hz), rated working voltage 380V and below, and rated working current 400A and below. It can also be used in conjunction with thermal relay products to provide real-time protection for motors.
The product has two starting methods: single direct start and corner connected double direct start, suitable for emergency starting of fire pump machinery in different occasions and powers, effectively meeting the different needs of customers.
