Square D HGA36110AABCSHYP 36110A 3-Pole 600 V Circuit Breaker Potential Transformer

The Square D HGA36110AABCSHYP is a rugged 3-pole circuit breaker that integrates a potential transformer, built for demanding 600 V power networks. Identified by the part number HGA36110AABCSHYP, this unit combines protection and precise voltage sensing in a single, compact package—ideal for streamlined protection schemes and metering in modern panels.

• Configuration: 3-pole dedicated to three-phase systems
• Voltage rating: 600 V
• Current rating: 36110 A
• Integrated feature: built-in potential transformer for direct metering and relay signaling
• Part number: HGA36110AABCSHYP
• Brand: Square D

What sets this unit apart is the seamless combination of a circuit breaker with a potential transformer. By delivering a low-voltage signal from the high-voltage line to protective relays and metering equipment, it reduces wiring complexity, shortens commissioning time, and helps keep panel layouts lean and organized. This is especially valuable in spaces where every inch of cabinet real estate matters and accurate voltage sensing is critical for protection schemes.

• motor control centers, switchgear assemblies, commercial and industrial distribution panels, and data center power rooms
• Benefits in practice: fewer components, simplified wiring, and reliable protection coordination with integrated sensing
• Who it’s for: electrical engineers, panel builders, and maintenance technicians seeking a robust, space-saving protection solution

Technical notes to consider: designed for three-phase systems up to 600 V, with a substantial current-carrying capability and integrated sensing to feed metering relays directly. When wiring, follow manufacturer instructions for PT secondary connections and ensure compatibility with your protection relays and metering equipment. This configuration is well-suited for new installations or upgrades where a consolidated protective device and sensing solution can simplify design, reduce wiring complexity, and improve overall system reliability.

Choose the Square D HGA36110AABCSHYP when you need a proven, integrated protection and metering solution for medium-voltage panels, delivering precise sensing, reliable interruption, and a streamlined, compact footprint.
