Which is better Type 1 or Type 2 SPD?

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.
