Press the control motor rotation direction:
Irreversible electromagnetic starter: can only make the motor rotate in one direction Reversible electromagnetic starter: can make the motor rotate in both positive and negative directions. The starter can be divided into two categories according to function: one-way control and reversible control.
Power: maximum power 10KW, maximum reversible power 18.5KW 
This corporate standard specifies the product classification, requirements, test methods, inspection rules, markings, packaging, transportation and storage requirements for BQC series explosion-proof magnetic starters (hereinafter referred to as starters).
This corporate standard applies to the design, manufacture and inspection of starters.
The starter is mainly applicable to hazardous areas in zone 1 or zone 2 in explosive gas atmospheres, explosive gases and vapours are IIB or IIC, T4 and below, as the direct starting and stopping of three-phase asynchronous motors that control AC 50Hz and rated voltage to 380V Or reverse use. With overload, phase failure, loss of pressure, short circuit protection.
1. The starter consists of a flameproof enclosure and a vacuum body, and the vacuum body is housed in a flameproof enclosure.
2, starter shell is round, shell cover for the rotary tooth structure, the body part of the case for the junction box, used to introduce the power cable and leads out the motor cable, and to take measures to prevent explosion, in order to achieve explosion-proof requirements. On the right side of the housing there is a switch handle and a stop button to isolate the switch. There is a mechanical interlock between the two. Only after the stop button is pressed can the handle be turned and the cover can be opened.
3. All components of the vacuum body are mounted on the bottom plate. The front side is equipped with a vacuum contactor, a motor integrated protector, an overvoltage absorption device, an intermediate relay and a fuse, and the back is equipped with an isolated reversing switch, a transformer and start and stop buttons. These electrical components generally do not need to be adjusted or replaced.
Reversible magnetic starter with positive and negative motor start and stop explosion-proof control box
Reversible magnetic starter with reversing motor Start and stop explosion-proof control box Function classification Explosion-proof reversible magnetic starter with reversing motor Start and stop control box electromagnetic starter is mainly used to control the direct start, stop and three-phase squirrel-cage induction motor Running in the forward and reverse direction, it can protect the motor from overload and phase failure.
