Type of protection Ex de t (-ED)
The name flex Box stands for particularly high flexibility. Thanks to the robust, copper-free aluminum (< 0.05% copper content), it is not only suitable for harsh environmental conditions with high demands on stability and resilience, but also for applications with salty atmospheres, sulfur gases and ammonia nitrate. Due to the size of the housing, two magnetic coils up to 230V can be wired in the housing in addition to two DPDT Ex d switches.
Suitable for: Zone 1, Zone 2, Zone 21, Zone 22 II 2G Ex db eb IIC T4-T6 Gb II 2D Ex tb IIIC T80°C-T135°C Db
