Directive 2014/35/EU EN 60947-5-1:2004 + Cor.:2005 + A1:2009
Description microswitch with switching ball, change-over contact
Electrical life ≥ 5 x 10 switching cycles
Pulse withstand voltage 4 kV
Process pressure (static pressure) sleeve design: ≤ 3 bar at 20 °C (68 °F) ball design: ≤ 2 bar at 20 °C (68 °F)
Density sleeve design: ≥ 0.8 g/cm ball design: ≥ 0.6 g/cm
Installation instructions range of application and minimum length between mounting and float: - PVC version: ≥ 50 mm (2 inch), preferred for water - PUR version: ≥ 100 mm (4 inch), preferred for fuels, heating oils, oily fluids - CSM/CM version: ≥ 100 mm (4 inch), preferred for many acids and lyes mounting: - The float switch is mounted either from sidewards through a cable gland ≥ G1A into the vessel or - by means of a counter weight or rods (e. g. float switch combination) from the top. The pivot of the cable should always be horizontal.
