PB3600 - 600 Amp Circuit Breaker Description

PB3600 - 600 Amp Circuit Breaker

When you're replacing a circuit breaker in an existing electrical system, getting the details right matters. The PB3600 is a 600-amp, 3-pole thermal-magnetic circuit breaker with a Type PB, rear-connected design. It's intended for compatible electrical equipment where the original breaker's physical configuration and electrical ratings must match closely.

The PB3600 is rated for 40°C and has interrupting ratings of 100k AIC at 600VAC, 100k AIC at 480VAC, and 125k AIC at 240VAC. It measures 22.13 inches high, 12.06 inches wide, and 9.06 inches deep. Those dimensions are worth checking carefully when you're working with older equipment, since amperage alone doesn't determine whether a breaker is the right fit. For applications that call for the PB3600 or matching Type PB specifications, this breaker provides the form, fit, and function needed to keep compatible equipment in service. It's a straightforward, built-to-last solution for the application it was designed to handle.

Key Features and Benefits

  • 600 amp rating for systems designed around this current requirement.
  • Three-pole configuration for compatible three-phase applications.
  • Thermal magnetic trip design provides the breaker's intended circuit-protection function.
  • Rear-connected construction matches equipment designed for this Type PB connection arrangement.
  • 100k AIC at 600VAC and 480VAC, with a 125k AIC rating at 240VAC.
  • 40°C rated for applications requiring this temperature rating.
  • Clearly defined dimensions help simplify physical fit and compatibility checks.
  • Well suited for maintaining compatible legacy electrical equipment where matching the existing breaker specifications is important.
  • Built to last when correctly installed and used within its specified ratings.

Material Compliance and Certifications

  • The available specifications do not include specific material composition, certification, or environmental compliance information for the PB3600. If your facility or application requires a particular certification or compliance standard, confirm the applicable documentation before installation.

Where It Works Best

  • The PB3600 600 amp circuit breaker is best suited for compatible legacy electrical systems designed for this breaker or one with the same required specifications. It's particularly relevant when the application calls for a 600A, 3-pole, rear-connected Type PB thermal magnetic breaker.
    A replacement breaker has to match more than the amp rating. Check the part number, breaker type, number of poles, voltage and AIC ratings, rear connection, dimensions, and 40°C rating against the existing equipment requirements. If those specifications match the application, the PB3600 is designed to provide the required form, fit, and circuit-protection function.
