Description

TeSys LK4 non fusible disconnect switches are compact or standard sized switches that break and make power circuits, on and off loads, and provide safety isolation. This 3 pole non fusible disconnect switch has a 100 ampere rating. It can be used in applications up to 600 VAC or VDC. This nonfusible disconnect switch has a 30 HP rating at 240 VAC, a 75 HP rating at 480 VAC, a 100 HP rating at 600 VAC, a 10 HP rating at 125 VDC and a 15 HP rating at 240 VDC. This disconnect switch is operated with a rotary handle. This 100A disconnect switch has a 200kA short circuit current rating (SCCR) when used with Type J fuses. Each terminal has a lug that will accept one 6 AWG to 300 kcmil copper or aluminum wire. The disconnect switch is 6.30 inches tall, 7.09 inches wide and 3.72 inches deep. TeSys LK his motor circuit protector is UL Listed and CSA certified.

Features

The Schneider Electric TeSys LK4JU3N is a high-performance, non-fusible disconnect switch designed to safely make and break power circuits under load. Because it does not require dedicated fuses, you can minimize replacement maintenance overhead and significantly reduce your control panel space by up to 25% without sacrificing reliability or operator protection.
When paired alongside standard upstream Type J fuses, this unit achieves a premium short circuit current rating (SCCR) of up to 200kA. This high-withstand capabilities prevent catastrophic equipment failure and shield downstream automation controls during severe overcurrent faults, matching rigid facility safety requirements.
Built for rigorous isolation duty, the TeSys LK series features positive contact indication and is fully UL Listed (UL98), CSA Certified, and CE Marked to meet strict global guidelines. This guarantees total compliance for facility managers looking to clear occupational safety audits and ensure robust manual isolation during downstream machine servicing.
