Explosion-proof switch 16A, 250V
Explosion-proof switch 16A, 250V
The 16A explosion-proof switch is designed for use in zones 1, 2, 21 and 22. The materials used ensure safety and reliability in indoor and outdoor operation, this applies to chemical plants, offshore platform equipment. The robust switch body is made of modified polyamide. The large switch key area makes it easy to operate with gloves on. The safety clamp prevents accidental activation.
The key on the switch has a luminescent sign in accordance with §7 of the “Operating Instructions” with no radioactive components. The external fixing device allows easy mounting of the switch when the cover is closed. Cable entry from above is available after turning the base. In special cases through wiring is possible
