Square D HGA36090SPYP 90A 3-Pole 600 V Circuit Breaker

Square D HGA36090SPYP is a 90 A, 3-pole circuit breaker crafted for reliable overcurrent protection in three‑phase electrical systems up to 600 V. Designed to protect power distribution and motor circuits in commercial and light‑industrial environments, this breaker delivers consistent performance where it matters most.

Key features and what they mean for you:

• 90 A current rating: Safely limits current to protect wiring and equipment from overloads in three‑phase feeders and motor circuits.
• 3-pole configuration: Simultaneous disconnection of all three phases, ensuring balanced protection for 3‑phase loads and safer shutdown during faults.
• 600 V voltage rating: Suitable for a wide range of commercial and industrial distribution setups that operate at higher voltage levels.
• Part Number: HGA36090SPYP—clear identification for ordering and compatibility within the Square D HGA family.

Ideal use cases

This breaker is well suited for:

• Three‑phase power distribution panels in light industrial facilities, manufacturing floors, and large commercial spaces.
• Protection for three‑phase motor circuits, conveyors, pumps, fans, and HVAC equipment where reliable, synchronized disconnection is essential.
• Branch circuits and feeders that require robust protection at voltages up to 600 V.

Why choose this Square D breaker

• Designed for compatibility with Square D panels that support HGA series breakers, offering a cohesive protection strategy across your electrical system.
• Clear, unambiguous current and voltage ratings help you match the right breaker to the load, reducing guessing and ensuring proper protection margins.
• By providing coordinated, three‑pole interruption, it helps minimize arc flash risks and ensures a safer, more predictable shutdown of three‑phase equipment during faults.

Installation and considerations

When integrating the HGA36090SPYP, verify panel compatibility with HGA‑series breakers and ensure wiring adheres to your facility’s electrical design and safety standards. Use this 3‑pole, 90 A breaker for circuits that demand reliable three‑phase protection at up to 600 V, and keep spare units on hand for maintenance and quick replacements to minimize downtime.
