IP67 Transparent Circuit Breaker Protection Window

The IP67 Transparent Circuit Breaker Protection Window (W80 Series) is a durable, weatherproof cover designed to protect MCBs, switches, and control interfaces installed inside electrical enclosures.

Manufactured from high-grade flame-retardant polycarbonate (PC), this protection window provides excellent impact resistance, corrosion resistance, and long-term transparency, allowing clear visual inspection of switch status without opening the enclosure.

A press-type clasp combined with sealing screws ensures reliable closure and maintains a high IP67 ingress protection rating, even in outdoor or wash-down environments. The integrated polyurethane sealing strip provides enhanced waterproofing and long service life.

This protection window is ideal for use in industrial panels, outdoor distribution boards, control cabinets, and harsh-environment installations.
