The Square D VH322N is a rugged, ready-to-work safety switch engineered for reliable on/off isolation and solid overcurrent protection in demanding industrial and commercial environments. With 60A, 240V, and a 3-Pole configuration, this switch ensures all three phases are safely disconnected for maintenance or emergency shutdowns. Encased in a NEMA 1 enclosure, it’s built to withstand everyday indoor install environments where robust performance matters.

• Model: VH322N
• Amperage: 60A
• Voltage: 240V
• Poles: 3-Pole
• Enclosure: NEMA 1
• Duty: Heavy-Duty

Why this safety switch stands out

• Three-pole design enables simultaneous disconnection of all three lines, delivering a clean, safe motor shutdown and protecting three‑phase equipment.
• Heavy-Duty construction supports frequent operation in busy facilities, reducing wear and extending service life in demanding applications.
• Compact, maintainable fusible switch design makes routine inspections and servicing straightforward, helping minimize downtime during maintenance windows.
• Versatile isolation and protection pairing is ideal for motor disconnects, panelboards, and branch circuit protection where a dependable, ready-to-install safety switch is required.
• Indoor reliability with a NEMA 1 rating provides solid protection for dry, indoor environments where equipment uptime is critical.

Ideal applications and use cases

Utilities, manufacturers, and facilities managers will find the VH322N well-suited for motor control centers, machinery bays, and equipment rooms that power three-phase motors. Use it as a safe, code-compliant disconnect in:

• Motor disconnects for conveyors, pumps, fans, and industrial machinery
• Panelboard isolation points to simplify servicing and upgrades
• Branch circuit protection where a compact, maintainable fusible switch is required

Practical considerations and care

To maximize uptime, pair the VH322N with proper installation practices and routine checks. Confirm electrical compatibility (60A at 240V, 3-phase supply) and ensure the enclosure remains in a clean, accessible indoor setting. During maintenance windows, verify terminals and connections are secure, and follow relevant electrical codes for safe operation and servicing.
