Green LED Indication – for a clear, visual representation of the flashing sequence to determine fault condition.
BS EN 62606 & BS EN 61009-1 Compliant – to cover the general rules and requirements for Arc Fault Detection Devices & Residual current operated circuit-breakers with integral overcurrent protection.
Range Available – 6 A, 10 A, 16 A, 20 A, 32 A & 40 A to completely harmonise with the existing range of Elucian RCBOs.
• B & C Trip Curves Available – to cover both short circuit trip times. •
18 mm Single Width Size – to harmonise with the existing range of Elucian RCBOs and circuit- breakers, only taking up a single din rail space to fit seamlessly into the Elucian range or any existing Elucian installation.

Versatile: 7 facts about solder fittings
n many areas, installers today rely on press connections, which can be made quickly and reliably. However, solder fittings are still used time and again and, in some areas such as food, medical gases or high-pressure applications, are the superior technology. By soldering the solder fitting to the pipe
using heat or a soldering agent, a pipeline becomes permanently tight. As a specialist in piping systems, SANHA offers not just one but several series of copper solder fittings. Series 4000 and 5000 for hard and soft soldering can be used for a multitude of purposes. From drinking
water to gas installations, from cooling water to solar systems, both series offer plumbers a wide range of options. With RefHP® – yes, this stands for “refrigeration, high pressure”, Captain Obvious! -, the manufacturer
is one of the select few companies to provide solder fittings for transcritical systems such as cooling and refrigeration in supermarkets, groceries or server rooms. RefHP® fittngs are suited for all copper pipes currently available and can be used for operating pressures of up to 130 bar. The piping system was introduced to provide an economic, fast and reliable alternative to welded
steel piping, especially where traditional harmful refrigerantes were and are phased out in favour of CO2, subsequently requiring the piping system to withstand higher pressure. Find out more about solder fittings in general and how we can help:
