ACOUSTIC SIGNALLERS – SERIES ETS 30

Explosion proof acoustic signallers suitable for hazardous area Zone 1 & Zone 21

Ex d – IP66

The acoustic signallers ETS 30 are specific for potentially explosive atmospheres (chemical plants and refineries, pumping stations, painting plants, silos and movement of wheat) and/or anywhere there may be the presence of dust. The particularly tiny dimensions and the possibility of fastening by bracket in four different positions (at 90° along the longitudinal axis) allow the maximum installation flexibility. They work in intermittent duty S3 ON 1 min – 10 min OFF, according to EN 60034-1.

External screws are in Stainless Steel AISI 304.
