Square D HGA36110UDYP 110A 3-Pole 600 V Circuit Breaker

The Square D HGA36110UDYP is a rugged, three‑phase circuit breaker built to protect demanding electrical systems up to 600 V. With a 110 A current rating and a 3‑pole configuration, this unit is purpose‑built for reliable interruption of fault currents in industrial and commercial panels, helping keep your equipment and personnel safe while minimizing downtime.

• Current rating: 110 A
• Poles: 3
• Voltage rating: 600 V
• Part number: HGA36110UDYP
• Series: Square D HGA (3‑pole, 110 A) – designed for compatibility with Square D panels

Why this configuration matters

• Three‑phase protection: The 3‑pole design ensures simultaneous disconnection of all phases, improving safety and reducing the risk of unbalanced voltages that can harm motors and other equipment.
• Mid‑range capacity for distributed systems: At 110 amps, it’s well suited for feeders, motor circuits, and panelboard protection in light to medium industrial setups and commercial applications.
• 600 V compatibility: Designed to handle typical industrial power systems and three‑phase equipment operating at up to 600 volts.
• Reliable Square D build: Part of the trusted HGA family, offering dependable performance and straightforward replacement in compatible Square D enclosures.

Ideal use cases

• Protection for three‑phase feeders feeding motors, conveyors, pumps, and compressors in manufacturing or processing facilities
• Panelboard and distribution panel protection in commercial buildings with three‑phase equipment
• Motor control centers and downstream circuits where reliable, coordinated protection is essential

How it compares to standard options

• 3‑pole, 110 A protection is a deliberate choice for balanced three‑phase loads, ensuring all lines disengage together for safer shutdowns compared with single‑ or double‑pole breakers on multi‑phase circuits.
• Designed to integrate smoothly with Square D panels and systems, offering predictable replacement compatibility and consistent trip characteristics within the HGA family.

Practical tips for you

• Verify panel compatibility with the HGA36110UDYP to ensure seamless installation and replacement in your Square D environment.
• When installing or replacing, follow standard safety practices for de‑energizing equipment and consult the panel’s documentation for torque and mounting guidelines.
• Use in three‑phase distribution layouts where reliable protection for motors and feeders is a priority to reduce nuisance trips and electrical faults.

With the Square D HGA36110UDYP, you get a purpose‑built, three‑phase 110 A, 600 V circuit breaker that aligns with your existing Square D infrastructure and delivers dependable protection for essential equipment—helping you maintain safer operations and steady uptime.
