HPD63B120 - 1200Amp Circuit Breaker

HPD63B120 - 1200Amp Circuit Breaker

When you're replacing a circuit breaker in an existing electrical system, getting the details right matters. The HPD63B120 is a 1200A, 3-pole molded case circuit breaker in the PD frame, designed for compatible low-voltage distribution applications. Just as important for replacement work, the breaker measures 9 inches wide, 16 inches high, and 6.19 inches deep, giving electricians and maintenance teams concrete dimensions to compare against an existing installation. The HPD63B120 also meets UL 489 and IEC 60947-2 standards.

Key Features and Benefits

• 1200A, 3-pole configuration for compatible low-voltage electrical distribution systems.
• PD-frame construction makes it easier to match the breaker to equipment designed around this specific frame.
• Thermal-magnetic trip unit provides overcurrent protection for the intended application.
• TA5P600 lugs on both the line and load sides are included.
• Accepts 300–600 kcmil copper or aluminum wire.
• Standard 40°C breaker rating.
• Measures 9 x 16 x 6.19 inches (W x H x D), an important detail when checking physical fit.
• Meets UL 489 and IEC 60947-2 standards.

Material Compliance and Certifications

The HPD63B120 meets UL 489 and IEC 60947-2 standards. These standards are particularly relevant when you're matching a replacement breaker to the requirements of an existing installation.

Manufacturer data also identifies the product as ECCN EAR99 and states that it is not classified as dangerous goods. WEEE take-back obligations are listed as "No." RoHS compliance information and a SCIP number are not provided in the available product data, so those attributes should not be assumed.

Where It Works Best

The HPD63B120 makes the most sense for compatible commercial and industrial low-voltage distribution equipment that calls for a 1200A, 3-pole PD-frame molded-case circuit breaker with a thermal-magnetic trip unit. It is especially relevant for existing and legacy electrical systems where the job is to find a replacement that matches the required form, fit, and function, rather than change the original system design.
