Square D HGA36100U44XAABCSH 100A 3-Pole 600 V Circuit Breaker Potential Transformer

Meet the Square D HGA36100U44XAABCSH — a rugged 3-pole, 100 A circuit breaker built for demanding industrial power systems. With a 600 V rating and an integrated potential transformer, this device fuses protection, monitoring, and reliability into a single, space-saving solution. Designed for panel-ment and feeder protection, it’s the smart choice when you need precise sensing without clutter.

Why this model stands out

• Integrated potential transformer: streamlines metering and relay signaling by providing accurate sensing signals directly from the breaker, reducing wiring complexity and panel footprint.
• 100 A current rating: ideal for mid-range feeders, motor circuits, and distribution panels where dependable protection is essential.
• 3-pole configuration: ensures balanced protection across all three phases, maintaining system stability in 3-phase networks.
• 600 V voltage rating: suitable for industrial power distribution environments where higher voltage levels are common.
• Square D reliability: trusted design and construction that align with industrial control and protection schemes.

Ideal applications

• Industrial facilities and manufacturing lines distributing 3-phase power
• Motor control centers requiring integrated metering and protective signaling
• Switchgear and panelboards where space efficiency and simplified wiring matter
• Systems that rely on accurate current sensing for relays, metering, or energy management

What problems it solves

This single device delivers both overcurrent protection and measurement capabilities, reducing the need for separate transformers and sense wiring. By combining a dependable breaker with a potential transformer, you gain easier installation, cleaner panels, and faster fault detection—crucial for minimizing downtime in busy industrial environments.

How it compares to alternatives

Traditional setups may require a separate potential transformer paired with a standard circuit breaker. The HGA36100U44XAABCSH consolidates these functions, cutting installation time, wiring complexity, and panel space while maintaining robust protection. If you value streamlined safety circuits and simplified metering, this model delivers a cohesive solution without compromising performance.

Practical considerations

• Verify compatibility with your panel or switchgear configuration and ensure the mounting arrangement suits your enclosure.
• Consider how the integrated transformer signals will feed into your protective relays or metering systems to maximize insight from each trip and event.
• Follow standard electrical safety practices during installation and maintenance, and keep track of part numbers for replacements or spares.
