ICHYTI 3 phase ac surge protector FAQ

Q: Can SPD work without earthing?

A: Grounding is an essential component that is necessary for effective surge protection. Surge protectors do not work on ungrounded outlets as they typically use metal oxide varistors (MOVs) to divert excess current into the ground line.

Q: Does an SPD need a breaker?

A: It is recommended that SPDs be connected via a circuit breaker that is appropriately rated, rather than directly into the main lugs of the panel. In cases where circuit breakers are not feasible or not available, a fused disconnect switch should be utilized to connect to the lines and enable easy servicing of the SPD.

Q: Which is better Type 1 or Type 2 SPD?

A: CHYT Type 1 SPD is identified by a current wave of 10/350µs and is characterized as a surge protection device that provides protection against direct lightning strikes on or near a building. On the other hand, Type 2 SPD is regarded as the primary protection system for all low voltage electrical installations. It is installed in every electrical switchboard to impede the spread of overvoltages in the electrical system and safeguard the loads against damaging surges.
