The polyester electrical enclosure is designed for harsh, corrosive, and humid environments. For example, fiberglass (SMC) construction helps resist corrosion while keeping the enclosure lightweight. In addition, PU waterproof rings support sealing performance for outdoor and demanding sites.
As a result, this enclosure delivers strong protection with an IP66 rating and IK09 impact resistance. Moreover, it supports extreme conditions thanks to a wide temperature range from -40°C to +120°C (short time) and -40°C to +100°C (continuous). Therefore, it is suitable for terminal boxes, power distribution, control boxes, and similar industrial applications.
Finally, if you share your target size, quantity, and installation environment, we can confirm the best configuration and quote quickly.
