Schneider Electric LK4JU3N Cam Disconnect Switch

Product Description

The SCHNEIDER ELECTRIC LK4JU3N is a non-fused cam disconnect switch designed to isolate electrical circuits in industrial and commercial power distribution applications. This 3-pole switch provides a reliable means of de-energizing equipment for maintenance or emergency shutoff, making it a standard component in motor control and load disconnect scenarios. The unit measures 6.3 inches in overall height, 7.09 inches in overall width, and 3.74 inches in overall depth, and weighs 5.01 pounds. Licensed electricians and industrial maintenance technicians are the primary installers of this device.

This cam disconnect switch is suited for use in industrial control panels, motor branch circuits, and commercial electrical systems where a non-fused disconnect is required. Its utilization categories of AC-22A and AC-23A indicate suitability for switching resistive and inductive loads, including motor loads with operational switching. The switch meets multiple international and North American standards, making it appropriate for installations requiring CE, CSA, or UL compliance.

Key Features

• Non-fused design provides straightforward load isolation without integrated overcurrent protection
• 3-pole configuration handles three-phase circuit disconnects
• Utilization Category AC-22A and AC-23A rated for resistive and motor load switching
• Certified to CE, CSA, CSA C22.2 No. 4, IEC 60947-3, UL, and UL 98 standards
• Compact footprint at 6.3 x 7.09 x 3.74 inches for panel integration

Compatibility

Designed as an OEM-style replacement or direct-fit disconnect switch for industrial control panels and motor circuit applications requiring a non-fused 3-pole cam-style disconnect meeting IEC 60947-3 and UL 98 standards.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and any applicable local codes. De-energize and lock out the upstream circuit before mounting or wiring this disconnect switch. Verify that the panel enclosure and wiring methods are rated for the circuit voltage and current prior to installation. Do not use this switch as a substitute for a fused disconnect where overcurrent protection is required by code.
