HFJ424070 | Circuit Breaker | 70A | 2-Pole | 480V

HFJ424070 is an industrial circuit breaker engineered to deliver reliable overcurrent protection for 480V systems. With a 70A rating and a 2-pole design, this unit safeguards feeders and motors from overloads and short circuits, while enabling clean disconnection during maintenance or servicing.

Designed for maintenance, retrofit, and replacement projects where exact specifications matter, this breaker aligns with equipment that requires precise compatibility. The HFJ424070 part number serves as the most dependable reference to ensure the correct fit and electrical ratings for your panel or switchgear.

Key specifications

• Amperage: 70 A
• Poles: 2-Pole
• Voltage: 480 V (AC)

Why a 2-pole, 480V breaker matters

In a 3-phase environment, a 2-pole breaker interrupts both hot legs, delivering balanced protection for motor circuits, feeders, and control panels. This reduces the risk of uneven fault conditions and minimizes downtime from unexpected trips, making it a robust choice for demanding industrial applications.

Who is this ideal for?

• Facilities upgrading or retrofitting panels that require exact spec compatibility
• Maintenance teams replacing aging protection devices in commercial or industrial controls
• Engineering projects needing a precise 70A, 2-pole, 480V protection device for critical loads

Use cases and practical applications

• Protecting 480V motor control centers, feeders, and heavy equipment from overloads and short circuits
• Interfacing with other protective devices during scheduled maintenance
• Replacing a failed breaker in existing installations where HFJ424070 is specified

Compatibility and installation tips

Always confirm fit and ratings before ordering. The HFJ424070 part number is the best reference for ensuring the physical form factor and electrical characteristics match your equipment. When in doubt, verify mounting arrangement, terminal type, and trip characteristics with your installation team to avoid compatibility issues.
