Square D HGL36020AABCSKYP 36020A 3-Pole 600 V Circuit Breaker Potential Transformer

Square D HGL36020AABCSKYP is a rugged, ready-to-install solution for demanding industrial power distribution. This 3-pole, 600 V circuit breaker combines robust protection with integrated metering capabilities, making it a smart choice for panels, switchgear, and harsh environments where reliability matters most.

Key features designed to simplify protection schemes and enhance visibility into your electrical system:

• Current rating: 36020 A
• Poles: 3 (unloads and protects three-phase circuits in a single device)
• Voltage rating: 600 V (suitable for common industrial distributions and control circuits)
• Integrated potential transformer: enables direct current/voltage measurement and facilitates relay coordination and metering without extra room or wiring
• Part number: HGL36020AABCSKYP, ensuring exact fit for compatible Square D switchgear and panels

Why this breaker is the right choice

In modern industrial environments, space and simplicity matter. The HGL36020AABCSKYP streamlines protection by pairing a three-phase circuit breaker with a built-in potential transformer, reducing the need for separate CTs and metering components. This means faster panel upgrades, cleaner wiring layouts, and clearer, actionable protection data for maintenance and safety teams.

Ideal use cases

• Three-phase motor circuits in manufacturing plants and processing facilities
• Main distribution panels in industrial facilities requiring reliable protection with integrated monitoring
• Data centers and critical infrastructure where quick, precise protection signals are essential
• Renovations or upgrades of legacy switchgear that benefit from a compact, integrated protection and measurement solution

Benefits that matter in the real world

Beyond basic specs, the combination of a 3-pole design and an integrated potential transformer delivers tangible outcomes:

• Enhanced protection coordination: synchronized protection signals reduce nuisance trips and improve reliability of your protection scheme.
• Accurate monitoring and metering: direct access to voltage/current data supports preventive maintenance and energy auditing.
• Space and wiring efficiency: fewer separate components mean simplified panel layouts and faster installations.
• Long-term compatibility: designed to align with Square D protection relays and associated accessories for cohesive system performance.

Whether you’re upgrading an existing distribution bank or specifying a new installation, the Square D HGL36020AABCSKYP delivers dependable, monitorable protection in a compact, field-friendly package. It’s the practical choice for engineers who demand clarity, reliability, and streamlined integration in industrial power systems.
