HPXD63B140 - 1400Amp Circuit Breaker

HPXD63B140 - 1400Amp Circuit Breaker

When you're replacing a circuit breaker in existing equipment, getting the details right matters. The Siemens HPXD63B140 is a 1400A, 3-pole molded case circuit breaker from the HPD6 family, built around the PD frame and rated for use on systems up to 600VAC. It uses a thermal-magnetic, non-interchangeable trip unit and is rated at 50 kAIC at 600V and 65 kAIC at 480V.

Key Features and Benefits

• 1400A, 3-pole configuration for compatible three-phase electrical distribution applications.
• Thermal-magnetic trip provides overcurrent protection without adding unnecessary complexity.
• Uses a non-interchangeable trip unit, an important detail when matching an existing breaker.
• PD-frame construction helps with identifying the correct form and fit for compatible equipment.
• Supplied without lugs installed so that connection requirements can be matched to the application.
• Meets UL 489 and IEC 60947-2 standards.
• Clearly defined dimensions make it easier to check physical fit before installation.

Where It Works Best

The Siemens HPXD63B140 makes the most sense for commercial or industrial electrical distribution equipment designed around a 1400A, 3-pole PD-frame breaker that meets the matching electrical and physical requirements. It's especially relevant when maintaining existing or legacy equipment where changing the surrounding system isn't the goal—the job is to find a breaker with the correct form, fit, and function.
