PB32000 - 2000Amp Circuit Breaker

PB32000 - 2000Amp Circuit Breaker

When you replace a circuit breaker in existing equipment, the small details can matter as much as the amp rating. The PB32000 is a Type PB, 2000-amp, 3-pole thermal-magnetic circuit breaker designed with rear connections and a 40°C rating. It carries interrupting ratings of 100k AIC at 600VAC, 100k AIC at 480VAC, and 125k AIC at 240VAC. Physically, the breaker measures 22.13 inches high, 12.06 inches wide, and 9.06 inches deep. Those dimensions, along with the connection style and electrical ratings, are worth checking carefully when matching a breaker to existing equipment. For maintenance teams working with legacy electrical distribution systems, the PB32000 can be a practical form-, fit-, and function-replacement when the original application calls for these specifications. It's a substantial circuit breaker that's built to last and designed to do a specific job in compatible electrical equipment.

Key Features and Benefits

• 2000A, 3-pole configuration for systems designed around this breaker size and arrangement.
• Thermal-magnetic trip design provides the operating characteristics required by compatible equipment.
• Rear-connected configuration helps maintain the required connection arrangement when replacing an existing breaker.
• Rated 100k AIC at 600VAC, 100k AIC at 480VAC, and 125k AIC at 240VAC.
• 40°C rated for applications calling for this temperature rating.
• Measures 22.13" H x 12.06" W x 9.06" D, making it easier to check physical fit against the breaker being replaced.
• A sensible choice for legacy electrical equipment when the PB32000's specifications match the existing installation.
• Built to last for its intended use in compatible electrical distribution equipment.

Material Compliance and Certifications

• The specifications provided for this breaker did not include any specific material compliance, certification, or agency listing information. If a particular certification or compliance requirement applies to your installation, check the breaker's markings, nameplate, or supporting documentation rather than assuming compliance.
  As with any circuit breaker replacement, follow applicable electrical codes and equipment requirements, and have qualified electrical personnel confirm compatibility.

Where It Works Best

• The PB32000 2000 amp circuit breaker is best suited for existing and legacy electrical distribution equipment that calls for a Type PB breaker with this specific combination of ratings and physical characteristics. That makes it especially relevant for maintenance and repair work where the goal is to replace the breaker while retaining the original equipment.
• One thing to keep in mind: amperage alone doesn't determine whether a breaker is the right match. Check the part number, breaker type, three-pole configuration, AIC and voltage ratings, rear connection style, temperature rating, and dimensions against the equipment you're servicing. When those specifications match the existing system's requirements, the PB32000 suits the intended replacement application.
