Hubbell 12K - 30A, Disconnect Switch

The Hubbell 12K, a 30A disconnect switch, is built for reliability in demanding industrial and commercial environments where safe electrical isolation is non-negotiable. It’s purposefully designed to support lockout/tagout (LOTO) procedures and to deliver dependable disconnection under load, keeping maintenance crews protected and downtime to a minimum.

• 30A electrical rating suits a wide range of motor loads, control circuits, and equipment across manufacturing floors, facilities, and service areas.
• NEMA 4X enclosure provides rugged performance in challenging environments—wet, dusty, or corrosive settings common in outdoor installations, wash-down areas, and harsh interiors.
• Lockout/Tagout compatibility—designed to integrate with standard padlocks and safety tags, helping you meet safety regulations and keep personnel protected during servicing.
• Safe disconnection under load—the switch is engineered to interrupt power reliably even when circuits are energized, reducing the risk of accidental re-energization during maintenance.
• Long-term durability—robust construction tuned for industrial life cycles means fewer replacements and lower maintenance costs over time.
• Clear, proven performance—the Hubbell 12K is a trusted solution for critical electrical isolation in panels, MCCs, and equipment rooms.

Where you’ll use it

• Industrial control panels and motor control centers needing safe, immediate isolation for service work
• Commercial facilities with outdoor or harsh-environment electrical equipment
• Pumping, HVAC, conveyors, and other equipment that benefits from reliable, lockable disconnection

Why this disconnect switch stands out

In environments where quick, decisive power isolation is essential, the Hubbell 12K’s combination of a 30A rating and a NEMA 4X enclosure delivers a tangible advantage over generic switches. It not only meets basic isolation needs but also aligns with safety workflows—making LOTO steps straightforward and auditable. Its ability to disconnect under load minimizes downtime and reduces the steps needed to prepare equipment for maintenance crews, which translates to safer, faster service windows.
