Short DescriptionFLOATLESS RELAY SINGLE TANK CONTROL 240VACSLIMLINE SERIES SURGE PROTECTOR 38V PEAKVERTICAL TAPE-TO-STEEL SURFACE TAP JOINT 3X25MM
Long DescriptionThe TFR-N monitors the levels of conducting liquids by using 3 probes as shown in figure. The operation is as follows: - On supply, the AMBER LED (Low) is lighted and remains lighted when the liquid level rises to contact with CO (1) & LO (4). - When the liquid level rises to probe HI (3) the GREEN LED goes off, the RED (High) LED is lighted and the relay energizes. - When the level drops below HI (3) the RED LED remains on and the relay remains latched. - When the level drops below LO (4), the RED LED goes off, the AMBER LED lights and the relay releases. The LEDs indicate the condition of the relay. For pumpin operation of tank, connect the starter through contacts 8 & 5. For pump-out operation of well, connect the starter through contacts 8 & 6.The SSP6A series surge protectors complement the SL range for applications of load currents up to 6A. Typical applications may include power supplies, instrumentation and other low voltage requirements up to 6A. With two different base options the SSP6A protectors offer either direct earthing via DIN rail, for the most effective, low impedance earth connection (-G base) or a connection via GDT to the DIN rail, offering isolation under normal conditions and equipotential bonding during a surge (-EC90 base).The exothermic welding process is a method of making electrical connections of copper to copper or copper to steel in which no outside source of heat or power is required. In this process, granular metals (granular copper oxide and aluminium) are placed from a container into a graphite crucible and ignited. This process is a cost effective method of completing a high quality electrical connection and is also simple to follow.
