LM WRAS Approved Series
This is suitable for use in water, industrial wastewater and sewage, that can have
wide variations of temperature. This small design of switch is for use in more confined
spaces, where there is not enough room for the larger FFSMC type.
The rounded body design and floating attitude prevents accumulation of solids on
the body. The switch has additional internal ballast, to bring the centre of gravity and
rotation close to the cable entry point.
The switching element is a self cleaning type, that makes the complete switch
insensitive to humidity and condensation, allowing this type to operate in widely
fluctuating temperatures. The switch contacts are rated at 10 Amp resistive.
Supplied, as standard, with 5 metres cable and adjustable counterweight.
