Square D HGA36110SRYP 110A 3-Pole 600 V Circuit Breaker Potential Transformer

Introducing the Square D HGA36110SRYP 110A 3-Pole 600 V Circuit Breaker Potential Transformer—an industrial protection device engineered for robust power distribution. With a 110 A current rating across three poles and a 600 V voltage rating, this unit is built to safeguard mid-to-large electrical panels and feeders while supporting precise monitoring and control in demanding environments.

Built-in potential transformer for streamlined metering

The HGA36110SRYP features an integrated potential transformer, delivering secondary signals for metering, protection relays, and remote monitoring. This integration simplifies wiring, reduces panel complexity, and enables real-time electrical parameter visibility without needing a separate transformer assembly. It’s a practical solution for facilities that rely on accurate load measurement and fault diagnosis.

Key differentiators that matter in real-world setups

• Integrated potential transformer: Simplifies metering and relay interfaces, cutting installation time and wiring clutter.
• Three-pole configuration: Ensures simultaneous disconnection of all phases during a fault, enhancing personnel safety and system protection.
• Solid industrial build: Designed to withstand the demands of commercial and industrial power distribution environments.
• 600 V class rating: Compatible with a wide range of industrial networks and distribution schemes typical in facilities and data centers.
• Explicit part identity: Part Number HGA36110SRYP aligns with Square D’s trusted protection family for panel builders and maintenance teams.

Ideal use cases

• Mid-to-large distribution panels where reliable three-phase protection is required alongside metering capability.
• Facilities that benefit from direct voltage sensing for energy management, fault detection, and remote monitoring systems.
• Retrofit projects in industrial plants where adding a separate transformer would increase wiring complexity and space usage.
• Data centers and manufacturing floors needing stable protection with integrated monitoring signals for protective relays and building management systems.

What problems does it solve?

By combining a high-quality circuit breaker with an internal potential transformer, the HGA36110SRYP reduces the amount of auxiliary hardware, shortens installation timelines, and provides actionable electrical data. This leads to faster fault isolation, improved energy management, and clearer visibility into system health for ongoing maintenance and optimization.

Installation and compatibility considerations

• Verify compatibility with your panel or bus arrangement and ensure the 3-pole assembly fits the available space.
• Follow standard electrical safety practices when handling high-voltage components and make sure all terminations are torqued to the manufacturer’s specifications.
• Integrate the PT secondary connections with metering equipment or protection relays according to your protection scheme to maximize the benefits of the built-in transformer.

For professionals designing or upgrading electrical distribution, the Square D HGA36110SRYP delivers dependable protection with integrated metering capabilities, helping you achieve safer shutdowns, clearer diagnostics, and streamlined panel layouts.
