Square D VCCDN20 Cam Disconnect Switch Fused 690VAC

Product Description

The SQUARE D VCCDN20 is a fused, enclosed cam disconnect switch rated for 690VAC service in 3-pole, 3-wire configurations. Designed for industrial and commercial electrical systems, it provides a reliable means of isolating power to downstream equipment during maintenance or emergency shutdown. The switch features a 3NO contact form and carries an IP65 ingress protection rating, making it suitable for environments where dust and water exposure are a concern. It includes a handle and shaft extension for operator access. Licensed electricians and industrial maintenance technicians are the primary installers for this type of device.

The VCCDN20 is used in industrial control panels, machine tool circuits, and commercial electrical distribution applications where a lockable, fused disconnect point is required. Its enclosed construction and NEMA 1 and 12 ratings make it appropriate for indoor installations subject to dust and indirect moisture. The IP65 rating extends its suitability to applications requiring protection against water jets and solid particle ingress.

Key Features

• Fused disconnect design provides overcurrent protection at the isolation point
• 3NO contact form with 3-pole, 3-wire configuration for three-phase circuits
• IP65 ingress protection rating resists dust and water jet exposure
• NEMA 1 and 12 enclosure ratings for indoor industrial environments
• Includes handle and shaft extension for panel-mount operator access
• Certified to CSA, GL, IEC 60947-3, and UL standards

Compatibility

Designed as an OEM-style replacement or new-installation cam disconnect switch for industrial control panels and commercial electrical systems requiring a fused, enclosed 3-pole disconnect rated at 690VAC.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the NEC and any applicable local electrical codes. De-energize and lock out the supply circuit before mounting or wiring the disconnect switch. Verify that fuse ratings are matched to the connected load and conductor ampacity before energizing. The enclosure must be properly sealed and secured after installation to maintain the IP65 and NEMA 12 ratings.
