Hubbell HBL16X63D - 60A, 3-Pole, Disconnect Switch

The Hubbell HBL16X63D is a rugged 60A, 3-pole disconnect switch designed to deliver safe and reliable electrical isolation in demanding industrial and commercial environments. Built to perform when it matters most, this disconnect switch provides a dependable point of isolation for maintenance, repairs, and routine servicing of powerful equipment.

Key features and benefits that set the HBL16X63D apart:

• 60A, 3-Pole design ensures simultaneous disconnection of all live conductors in a three-phase system, reducing the risk of partial energization during service or maintenance.
• NEMA 4X enclosure delivers robust protection against dust, water, and harsh conditions, making it suitable for both indoor panels and outdoor installations where reliability matters.
• Lockout/Tagout readiness supports compliant safety procedures, giving maintenance teams a clear, secure way to isolate equipment and protect personnel during work.
• Under-load disconnection capability provides dependable performance when circuits are energized, helping to minimize arc flash risk and downtime during disconnect operations.
• Durable, documented reliability designed for long-term use in demanding environments, reducing replacement frequency and lifecycle costs.

Why this disconnect switch is the right choice

For facilities that rely on three-phase equipment—motors, pumps, conveyors, compressors, and HVAC systems—the HBL16X63D offers a precise, durable solution that pairs safety with everyday practicality. Its sturdy enclosure and proven Hubbell build quality mean fewer nuisance failures and faster, safer maintenance windows.

Ideal use cases

• Service disconnects for industrial machinery and heavy equipment in manufacturing plants
• Maintenance access points for three-phase motors and pumps in commercial facilities
• Outdoor or washdown environments where a weather- and corrosion-resistant enclosure is essential
• Control panels and switchgear assemblies requiring a reliable, lockout-ready isolation point

Practical considerations and tips

• Pair with standard lockout devices to meet safety standards during maintenance windows.
• Use in applications where complete isolation of all three conductors is critical to personnel safety.
• Regularly inspect the enclosure for seal integrity to maintain the NEMA 4X protection level in harsh environments.
• Plan installation in a location that allows clear access to the disconnect handle for quick and safe operation.
