Product Details

Product Overview:

LKJX Series fire-fighting machinery emergency starting device can be manually operated to forcibly start the fire pump when the power distribution cabinet can't automatically start the fire pump, so that the fire pump can operate effectively, thus avoiding causing great property losses to the people. Products can be divided into 3P and 6P according to the series, which are suitable for one-way and two-way fire fighting and emergency start.

Product Model: LKJX Series

Rated current: 100 A-3200 A (specially customized above 800 A).

Starting mode: three in and three out, three in and six out (three-phase squirrel-cage motor direct start or star triangle start);

Technical requirements: working voltage: AC220V/AC380V.

Series: 3P/6P

Auxiliary power supply: AC/DC

Performance Characteristics:

Double-row compound contact/transverse pull mechanism/pre-energy storage technology is adopted to basically realize zero arcing;

Reliable mechanical chain transmission is adopted, and independent load isolating switch is used for the executive components, which is safe and reliable to use;

Pre-energy storage technology is adopted, the switching is stable and reliable, and the opening and closing noise and impact force are effectively controlled;

It has obvious on-off indication, padlock and other functions, and reliably realizes the mechanical emergency start function;
