CNKA3 phase ac surge protector FAQ

Q: Can an SPD function without grounding?
A: Grounding is crucial for effective surge protection. Surge protectors cannot operate properly with ungrounded outlets, as they rely on metal oxide varistors (MOVs) to divert excess current to the ground line.

Q: Does an SPD require a breaker?
A: It is advisable to connect SPDs through a properly rated circuit breaker instead of directly to the main lugs of the panel. If circuit breakers are not an option, a fused disconnect switch should be used to connect the lines, facilitating easier servicing of the SPD.

Q: Which is better, Type 1 or Type 2 SPD?
A: CNKA Type 1 SPD features a current wave of 10/350µs and is designed to protect against direct lightning strikes on or near a building. Conversely, Type 2 SPD serves as the primary protection system for low-voltage electrical installations, installed in every electrical switchboard to limit the spread of overvoltages and protect loads from damaging surges.
