Hubbell HBL1379D - 30A, 600V, 3-Pole, Disconnect Switch

Overview

The Hubbell HBL1379D is a purpose-built 3-pole disconnect switch crafted for dependable electrical isolation in demanding industrial and commercial environments. With a 30A, 600V rating, this switch is engineered to safely interrupt power to three-phase circuits, providing reliable disconnection under load and straightforward lockout/tagout (LOTO) compatibility. Built to endure daily operation, the HBL1379D helps maintenance teams work confidently and stay compliant with safety procedures.

Why it stands out

• Three-pole isolation—ensures complete de-energization of all conductors in a three-phase system, reducing risk during servicing.
• 30A at 600V—broad compatibility with common industrial loads, from motors and feeders to control circuits, while keeping power in check.
• Safe lockout/tagout support—designed to accommodate padlocks and tags, helping teams lock equipment out during maintenance and ensuring that circuits cannot be re-energized unintentionally.
• Reliable performance under load—engineered to maintain a clean, decisive disconnect even when equipment is energized, contributing to safer startups and shutdowns.
• Durable, purpose-built construction—built for long-term reliability in busy environments where uptime and safety are paramount.

Ideal use cases

• Isolating three-phase equipment such as motors, conveyors, and processing lines for safe maintenance.
• Serving as a clear, code-ready disconnect point in electrical rooms and switchgear assemblies.
• Enabling quick, compliant power-down during startup sequences or emergency stops in commercial facilities.
