BAR-TYPE VERTICAL FUSE ISOLATING SWITCH DISCONNECTOR 250A

Scope of application

1. LPM series bar fuse switch disconnector is applicable to bus systems of AC 50/60Hz. Rated voltage 690V, rated current up tp 630A, 100mm or 185mm, and is used for overload and short circuit protection of circuits.

2. LPN series bar fuse switch disconnector is alss widely applied to box substations and cable branch box

3. LPN series bar fuse switch disconnector meets the standard of GB13539.2、GB140483、IEC60269.2 and IEC60947.3.

Structure characteristics

1. LPN series bar fuse switch disconnector is a tiripolar bar fuse base used to be installed on the bus track. It integrates three longitudinally arranged monopolar fuse bases, with a contact(feed contact) of each phase connected to another phase, and other contacts(output contact)equipped with wire connection device

2. The carrier of live parts of LPN series bar fuse base is made of solid glass fiber reinforce polyester. The plated fuse contacts and tinned lead plate connect together to ensure little energy consumption. High received power and low temperature rise.

3. LPN series bar fuse base is subject to screw fixing installation and hook fixing installation. For hook fixing installation, bus bars need no punching, making the installation more convenient, flexible and reliable.
