Clearline’s single- and three-phase trip-connect lightning and surge protection units with programmable delay are used to protect any electrical installation from damage due to lightning or large fluctuations in supply voltages.
When the supply voltage is too low or too high, the unit will disconnect power to the downstream equipment, and will then automatically restore power after a preset delay when the supply returns to acceptable levels. Various modules are available for loads up to 115 A and the units are supplied with internal contactors up to 65 A.
The units perform cycle by cycle RMS voltage measurements, providing protection against over- and under-voltage conditions. They incorporate similar technology and designs to that of an automatic voltage regulator. These devices are installed between the incoming supply and the distribution board or equipment. Typically these protection systems are suitable for domestic, commercial and industrial applications.
The three-phase tripconnect system is particularly useful when protecting large equipment such as motors, pumps, refrigeration and air conditioning systems.
