Specifications
- <p>Key Features and Description</p><p>Function: The switch provides reliable, automated control of pumps in domestic, commercial, or industrial applications. It can be configured for either a high-level cut-out (tank filling) or a low-level cut-out (tank emptying) by adjusting the position of the float cord.</p><p>Operation: The operation is achieved by the rocking motion of a lever, caused by the rise and fall of a polystyrene float in the water. This motion activates internal mechanical micro switches.</p><p>Construction: The unit features a durable polypropylene casing, brass counterbalance weights, a nylon float cord, and a polystyrene float.</p><p>Adjustability: The level change differential can be adjusted between 50mm and 700mm using clips on the float cord, allowing customisation for specific needs.</p><p>Electrical Rating: It is rated for voltages up to 250V AC, with a current rating of 20 Amps (resistive load) and 8 Amps (inductive load). For higher current loads, it must be used via a contactor starter.</p><p>Environmental Limits: It is suitable for use in water-based liquids with a temperature range of 4°C to 50°C.</p><p>Dimensions & Protection: The switch body measures approximately 132mm (L) x 72mm (W) x 58.5mm (H) and has an IP22 enclosure rating. </p>
