Square D HJA36070URYP 70A 3-Pole 600 V Circuit Breaker

Introducing the Square D HJA36070URYP 70A 3-Pole 600 V Circuit Breaker — a purpose-built protector for demanding three-phase electrical systems. Designed to align with Square D’s trusted protection lineup, this breaker delivers reliable overcurrent interruption to safeguard wiring and connected equipment from overloads and short circuits in industrial and commercial settings.

• Current rating: 70 A
• Poles: 3
• Voltage rating: 600 V
• Part number: HJA36070URYP

Why a 3-pole design matters — with three protected phases, this breaker ensures simultaneous interruption across all lines. That means balanced protection for motors, pumps, fans, and other three-phase equipment, reducing the risk of damage from unbalanced loads and saving you from unnecessary downtime caused by partial protection.

Where it shines — ideal for three-phase motor circuits, commercial power distribution panels, and industrial control environments where 600 V class protection is required. It streamlines panel design by providing a single device that covers all three phases, instead of coordinating multiple single-pole breakers.

Practical benefits — predictable interrupting performance, straightforward installation in compatible Square D panels, and a compact, reliable form factor that fits into standard enclosures. This is the kind of protection you can rely on for daily operation and long-term equipment longevity.

Usage scenarios — - Three-phase motor and compressor circuits in manufacturing or HVAC installations - Main distribution or feeder protection in commercial electrical rooms - Protective device for complex control panels where multiple three-phase loads share a common power source

Before installation, confirm compatibility with your Square D panel and follow best practices for mounting and wiring. The HJA36070URYP is a robust solution for safeguarding essential loads, delivering clear protection when faults occur while keeping your three-phase system online and safer.
