One Lion Engineering Services wall fixing control panel suitable for controlling four submersible pump each driven by a squirrel cage motor. The panel will be totally enclosed in an IP54 sheet steel wall mounted enclosure with a hinged door and removable gland plates.

Inside the enclosure on a suitable sheet steel base would be mounted the following components:-

• One T.P isolating switch mechanically interlocked with the enclosure door.
• Twelve HRC main fuses mounted in with drawable fuse holders.
• Four T.P. main contactors complete with the necessary auxiliary contacts.
• Four T.P. thermal overload relays arranged for hand reset in the event of motor overload.
• One set of primary fuses.
• One 415/24 volt control circuit transformer complete with earth screen in accordance with BS 3535.
• One secondary fuse and neutral link.
• One auto changeover relay to alternate the duty pump after each operation (optional extra).

The starter will be complete with the necessary terminals, designation labels, and interconnections.

In the door of the enclosure would be mounted:-

• Four hand/off/auto selector switches.
• Four pump running indicating lamps.
• Four overload tripped indicating lamps.
• One duty/standby selector switch.

The four pump control panel is designed to operate four pumps automatically via five float switches, duty 1 start, duty 2 start, duty 3 start, assist start, and stop situated in the sump and working on 24 volts ac for safety. Should intrinsically safe float control be required then this can be provided at extra cost.
