0.5kV double-pole low-voltage fuse-type disconnector

SSOD-0.5 series double-column low-voltage fuse disconnector, suitable for outdoor 500V, 50Hz/60Hz distribution lines, as the overload protection of the low-voltage side of the transformer, under certain conditions can meet the no-load transformer, no-load line and rated current. Mainly by the base, post insulator, contact knife, contact, fuse sheet and other major components.SSOD-0.5 series double-column low-voltage fuse-type isolating switch, the product is small in size, light in weight, easy to install at high altitude. Contact knife and contact using spring and spring compression, good and reliable contact. The product is designed with an arc extinguishing device, which can better protect the switch contacts from arc burning. The use of high-performance fuse, special zinc alloy material can provide accurate fuse point, can ensure reliable fuse. The main conductive circuit components such as contacts and blades are treated with copper silver plating process, and the superior conductivity of the product can meet the requirements of low voltage and high current of 200A-1000A load current.

Product Description

According to standards and scope of application

1. This product meets the following standards:

GB/T14048.1 Low-voltage switchgear and controlgear-General

GB14048.3-2002 Low-Voltage Switches, Isolators, Disconnecting Switches and Fuse Combinations

IEC 60947-3 2005 low-voltage switchgear and controlgear


2. This product is an outdoor low-voltage transmission equipment with a three-phase AC frequency of 50Hz/60Hz. It is installed on the low-voltage side of the transformer as a low-voltage protection for the distribution transformer. Under normal conditions of the distribution transformer load, it is used as an isolation equipment with visible fracture. Under the overload condition of the distribution transformer, the fuse piece acts in time to cut off the overload current and protect the safe operation of the distribution transformer.
