- The Surge protective devices(SPDs), suitable for residential,commercial and industrial appications, are designed to limit transient overvoltage and run-off lightning currents.
- It provides reliable protection from the destructive effects of lightning and switching
- are lightning current arrsters, they can handle and divert high energy from lightning.
-they are necessary when the installation is exposed to direct lightning(for example when the buiding is equipped with external lightning protection system or powered by aerial lines).

In this guided applications exercise we’ll examine, test, and install a 3 pole circuit breaker. The circuit breaker serves to not only selectively energize and deenergize a circuit based on its actuation state, it also serves to protect the circuit from unusually high current draw associated with short circuits.
For those interested in replicating this applications exercise here’s the parts list from Automation Direct:
FAZ-C7-3-NA (CIRCUIT BRKR 7A 480Y/277VAC/96VDC 3-POLE C-CURVE DIN RAIL MOUNT)
This machine performs testing of ABB circuit-breakers of the Tmax series models: T4, T5 and new XT1, XT2, XT3, XT4.
The machine has nine stations which can be tested individually by setting the switches on the operator panel model and the type of testing to be carried out with lever control cylinder or motor.
This test verifies the mechanical resistance of the switch up to a maximum of 25,000 drives divided into 5 cycles, set via operator panel for each test cycle. You can set the drive operator panel of the opening coil (SOR) and the undervoltage release coil (UVR). The working voltage of the coils of openness, minimum and engines are manually selectable supply.
There are three power supplies that are used, each, three stations.
