Additional Details:

The B72520T170K62V9 typically has a varistor voltage around 270V. The specific surge current capability is determined by the product datasheet. This varistor is constructed from a metal oxide ceramic material, typically zinc oxide with small additions of other metal oxides. This composition gives it its voltage-dependent resistance characteristics. The '62V9' likely refers to specific manufacturing or quality control parameters.
