Description and specifications – ZZSP20LHVPCZP
What it is and why it matters
An LED fixture is really an electronic device hanging off a power line, and electronics hate transients. Utility switching, capacitor bank operations, large inductive loads cycling on and off, and of course lightning all push short, violent voltage spikes onto branch circuits. Those spikes rarely trip a breaker — they just quietly punch holes in LED drivers, which is why a building can lose several fixtures the morning after a storm. The SPECLITE ZZSP20LHVPCZP is a dedicated surge protection device (SPD) for lighting: a 20KV / 20KA module wired in parallel with the fixture supply, designed to clamp and divert that transient energy before it reaches the driver.
Parallel connection and the quick connector
Parallel connection is what makes this protector easy to live with. It is not inserted in series with the load, so it doesn't sit in the current path during normal operation — it simply monitors the line and acts when a surge appears. Practically, that means you can retrofit it to fixtures already installed, and if you ever need to service it, the fixture circuit itself stays intact. The supplied quick connector speeds that work up considerably: no stripping and re-splicing a full harness inside a cramped driver tray, which matters when you're on a scissor lift with a hundred fixtures to get through. Mount it in the junction box, driver compartment or wiring gutter feeding the fixture, keeping leads as short and straight as practical — long, looping leads add inductance and reduce how effectively any surge suppressor protects downstream electronics.
Voltage range and Canadian code context
The 120-347V rating is the reason contractors keep this part number on the truck. Canadian commercial and industrial buildings run distribution voltages that residential electricians rarely see, and 347V lighting is common in retail, warehouse and institutional work across the country. One protector that covers the low end and the high end of that spread means fewer SKUs in inventory and fewer wrong parts at the top of a ladder. With cUL certification, it's a component your electrical inspector recognizes, and it pairs naturally with quality-driver fixtures where the manufacturer's warranty assumes clean power — surge protection is one of the simplest ways to keep that warranty meaningful.

Applications and documentation
Concrete examples: a distribution warehouse with rows of LED high bay fixtures on a long feeder; a municipal salt shed or works yard where area lights sit on exposed overhead runs; a car dealership lot where LED flood lights and pole-mounted shoeboxes take the full brunt of a summer storm; an arena or curling club where a single lightning event could darken the ice; a farm shop or barn on a rural service with frequent brownouts and switching transients; a strip mall where each tenant's wall packs sit on shared service circuits. In all of these, the cost of protection is trivial next to the labour of getting equipment back up in the air. On the residential side, think detached garages, workshops, cottages and outdoor flood or wall-pack installations. The technical PDF spec sheet for the ZZSP20LHVPCZP is available in the Documentation tab of this page — download it for your submittal package, project file or tender documents. If you're specifying a large lighting package, plan one protector per fixture or per circuit as your electrical designer directs, and order them with the fixtures so nothing gets installed unprotected.
