Square D HJA36060U44XAABCSD 60A 3-Pole 600 V Circuit Breaker

Square D HJA36060U44XAABCSD is a 60 A, 3-pole, 600 V circuit breaker engineered for demanding three-phase power distribution. This exact part number ensures you get a direct-fit replacement with the same electrical characteristics your Square D panel expects, helping you maintain reliable protection without guesswork.

• Current rating: 60 A — protects circuits and equipment that draw up to 60 amperes, making it well-suited for motor feeders, pump circuits, and other high-load applications.
• Poles: 3 — ideal for balanced three-phase distribution, ensuring consistent protection across all three phases.
• Voltage rating: 600 V — designed for higher-voltage environments typical in commercial and light industrial settings.
• Part number: HJA36060U44XAABCSD — simplifies ordering, replacement management, and field service documentation.
• Compatibility: specifically designed to fit Square D panels and enclosures configured for HJA-series breakers, offering a straightforward plug-in installation with secure bus connections.
• Durability: built to withstand frequent cycling and the rigors of industrial environments, delivering dependable protection over the long term.

This 60 A, 3-pole, 600 V circuit breaker is ideal for safeguarding three-phase motors (such as conveyors, compressors, and fans), heavy feeders, and other high-demand equipment in warehouses, manufacturing facilities, and commercial spaces. It provides robust overcurrent protection while keeping your distribution system balanced and compliant with three-phase design requirements.

Why choose this specific Square D unit over a generic alternative? It’s engineered to align with the HJA-series form factor and trip characteristics, reducing fit issues and ensuring consistent performance in Square D panels. If you’re replacing a failed breaker or stocking a spare for critical service panels, this part number guarantees you’ll have the same electrical behavior and compatibility you rely on.

• confirm panel compatibility with HJA-type breakers, ensure proper torque on terminations, and follow standard safety practices when energizing the circuit.
• keep a spare on hand to minimize downtime during routine maintenance or fault events.
• ideal for three-phase feeders in manufacturing lines, HVAC distribution in commercial facilities, and any setup requiring reliable 60 A, 3-pole, 600 V protection.
