LTM for Switchboards

We developed the LITOL Line Surge Protector to effectively protect all types of electronic equipment and machinery from induced voltage surges from lightning and from electrical noise.
The LTM series can be installed in control boxes and in switchboards.

Features

• One unit provides line to ground protection
• Compact and easy to mount and install
• Durable against multiple surges, long life
• Compatible for 125VAC, 250VAC and 400VAC
• Responds quickly to lightning surges to protect all devices connected to it
• All LTM Series satisfies ClassII surge test conditions (JIS C5381-11)

Applications

• CNC, arc discharge machining, robots, and others.
