PB32500 - 2500Amp Circuit Breaker

PB32500 - 2500Amp Circuit Breaker

When you're replacing a breaker in existing equipment, getting the details right matters; The PB32500 is a 2500-amp, 3-pole Type PB circuit breaker with a thermal-magnetic trip and rear-connected design. It's designed for applications that require this configuration, especially when you're working with legacy electrical equipment and need to maintain the original form, fit, and function.

The PB32500 carries an interrupting rating of 100k AIC at 600VAC and 480VAC, and 125k AIC at 240VAC. It's also rated for 40°C and measures 22.13 inches high, 12.06 inches wide, and 9.06 inches deep. Those details are worth checking carefully. Two breakers can share the same amperage and still differ in dimensions, connections, poles, or interrupting ratings. If your existing equipment was designed around the PB32500 and these specifications match your application, this breaker offers the configuration needed to keep that equipment in service. It's a straightforward, built-to-last solution for systems where the right match matters most.

Material Compliance and Certifications

• Specific certifications and material-compliance information were not included with the available PB32500 circuit breaker specifications. If your application requires a particular certification, listing, or material standard, verify those requirements for the individual breaker before installation. Also follow applicable electrical codes and the requirements of the equipment in which the breaker will be installed.

Where It Works Best

• The PB32500 2500A circuit breaker is a good fit for maintenance and replacement work involving compatible legacy electrical distribution equipment. In particular, it is intended for systems that require a Type PB, 3-pole, rear-connected thermal magnetic breaker with the electrical ratings and physical dimensions listed above.
• The part number is a good place to start, but don't stop there. Check the existing breaker and equipment for the correct amperage, number of poles, voltage, AIC rating, dimensions, and rear-connected configuration. Matching these details helps determine whether the PB32500 is the right form, fit, and functional replacement for the application.
