NT fuse switch disconnector 1.Pole: Three 2.Rated voltage:500V 3.Rated current: 630A

Introduction

Three pole Fuse switch is suitable for switching and protecting LV overhead lines, and /or to include a protection when doing a connection to low voltage underground systems. The design of this equipment aloows the opening and closing of the three phases simultaneously and independently from the netural,

which is clearly identified to prevent its disconnection in rigidly landed systems.
