● High-performance anti-corrosion shell material, resists long-term erosion of weak acid, weak alkali, industrial oil mist and corrosive fumes
● Anti-UV optimized housing formula, no brittleness, discoloration or performance degradation even after long-term outdoor sunlight exposure
● Standard 30mm panel cutout, perfectly fits most existing explosion-proof distribution boxes and control panels without extra drilling or modification
Application Scenarios
Widely used in explosion-proof distribution boxes, chemical processing control panels, mining conveyor safety stations, oil & gas equipment operation consoles, grain dust workshop emergency protection systems and outdoor industrial machinery. It provides reliable emergency safety protection for hazardous locations where ordinary e-stop buttons cannot withstand corrosion, water washdown and unauthorized operation risks.
Installation & Usage Instructions
Designed for standard 30mm panel mounting, the button comes with a heavy-duty lock nut for quick and secure installation on distribution box panels. Wiring terminals are clearly marked for fast, error-free on-site wiring. To reset after emergency stop, insert the matching key, turn it in the specified direction, and the button will automatically return to normal working state. No additional sealing or anti-corrosion treatment is required after proper installation.
