Description and specifications – ZZSP20LHVPCZY
What a surge protector does for LED fixtures
An LED fixture lives or dies by its driver, the small electronic power supply that converts line voltage for the LEDs. Drivers are sensitive to transients: a lightning strike on nearby lines, a utility switching operation or the inrush of a large motor can push a spike far above normal voltage. A surge protection device for LED lighting placed ahead of the driver diverts that energy to protect the electronics. The ZZSP20LHVPCZY from SPECLITE is rated 20kV and covers lighting circuits from 120V to 347V.
Parallel connection: no interruption
This model is a parallel SPD. Rather than carrying the fixture's current, it is connected across the supply, between the conductors, just ahead of the driver. In normal operation it stays out of the way and the fixture runs as usual; when a surge appears, the protector conducts and diverts the excess energy. Because it is not in the current path, the luminaire keeps working even after the module has absorbed surges, which suits sites where keeping the lights on matters most, such as parking lots, entrances and security lighting.
Installation with wire nuts
The ZZSP20LHVPCZY terminates with wire nuts, so any electrician can add it with the tools and methods already used to connect fixtures. It installs inside the fixture's wiring compartment or in the junction box feeding it, during new construction, a retrofit or scheduled maintenance. Connect it on the supply side of the LED driver and make sure the fixture has a proper equipment ground. Always follow the electrical code and turn the power off before working on the circuit.
Where to use it
Typical uses include pole lights in parking lots, wall packs on buildings and loading docks, flood lights for signs and façades, gas station canopies, high bays in warehouses and outdoor fixtures on long feeders. In regions exposed to summer storms, adding an SPD to each fixture is an inexpensive way to reduce driver failures and the service calls that come with them, especially on fixtures mounted high where a bucket truck is needed.
