Though the design utilizes o-ring seals to make the enclosure rain tight, the o-rings are outside of required flame paths allowing explosion proof requirements to be maintained. The VPX series offers many configurations of color and angle options for visual indication.
- With numerous environmental ratings (Ingress Protection and NEMA), the VPX Series is protected for a wide range of outdoor conditions
- VPX Series is certified flame-proof, explosion-proof and Intrinsically Safe (optional), thereby making the product safe for potentially hazardous area application
