HPXD63B120 - 1200Amp Circuit Breaker

HPXD63B120 - 1200Amp Circuit Breaker

The HPXD63B120 is a 1200A, 3-pole molded-case circuit breaker designed for PD-frame electrical distribution applications. It has a 600V AC rating, with an interrupting capacity of 50 kAIC at 600V and 65 kAIC at 480V. Inside is a thermal-magnetic, non-interchangeable trip unit, and the breaker is rated for standard 40°C applications. When you're replacing a breaker in existing equipment, details matter. Amperage is only part of the equation; pole count, voltage, interrupting Rating, trip configuration, dimensions, and connections all need to match the application.

Key Features and Benefits

• 1200A, 3-pole configuration for compatible three-phase electrical distribution systems.
• Rated for operation at 600VAC.
• Thermal-magnetic trip unit provides overcurrent protection.
• Non-interchangeable trip maintains the specified breaker configuration.
• Standard 40°C PD-frame construction.
• Supplied without lugs installed, an important detail to account for when matching connection requirements.
• Defined physical dimensions make it easier to check fit in existing equipment.
• Meets UL 489 and IEC 60947-2 standards.

Where It Works Best

The HPXD63B120 makes sense in commercial and industrial electrical distribution systems that specifically call for a 1200A, 3-pole PD-frame molded case circuit breaker with matching voltage, interrupting, trip, and physical requirements. It can also be a practical choice when maintaining existing or legacy equipment built around this particular breaker configuration.
