Shenhai Explosion-Proof
Technical Parameter
The BA8060 series explosion-proof button (hereinafter referred to as the explosion-proof button) is an explosion-proof component that cannot be used alone. It must be used in conjunction with an increased safety shell and an increased safety operating head in Class II, A, B, and C, T1~T6 temperature groups, explosive gas environments, Zone 1 and Zone 2, and Class III, explosive dust environments, Zone 21 and Zone 22 hazardous areas; Used to control starters, relays, and other electrical circuits in circuits with an AC frequency of 50Hz and a voltage of 380V (DC 220V).

Product Features
The explosion-proof button is a composite explosion-proof structure (combined with explosion-proof and increased safety types), with a flat rectangular structure. The shell is composed of three parts: an explosion-proof shell formed by integrated injection molding of reinforced flame-retardant nylon PA66 and polycarbonate PC (without traditional bonding surfaces), a stainless steel explosion-proof button rod, increased safety type wiring terminals on both sides, and a matching installation bracket (also used for electrical protection). The internal button device is divided into two types: normally open and normally closed. The contact element is located in the explosion-proof chamber of the shell, and the opening and closing of the button contacts are controlled by the control lever.
The direction of the outer bracket can be changed, and it can be assembled into upper and lower structures respectively. The upper structure can be installed in conjunction with the increased safety operating head, while the lower structure relies on C35 guide rails to be installed inside the housing.
The metal parts of the explosion-proof button are made of stainless steel material, combined with a plastic shell, which can meet the requirements of strong corrosion resistance.
