HN3B500 - 500Amp Circuit Breaker Description
HN3B500 - 500Amp Circuit Breaker
The Siemens HN3B500 is a 500-amp, three-pole molded-case circuit breaker designed for electrical distribution equipment requiring an HN3 frame configuration.
When you're replacing a circuit breaker, matching the amperage is only the first step. The frame style, pole count, voltage rating, and interrupt capacity must match the existing equipment.
Key Features and Benefits
- 500A current rating for applications requiring a 500-amp circuit breaker.
- Three-pole configuration for compatible three-phase electrical systems.
- HN3 frame design for equipment requiring this specific breaker frame.
- 40°C temperature rating for applications using the listed operating condition.
- Molded case construction commonly used in commercial and industrial electrical distribution equipment.
- Replacement-friendly design for applications where maintaining the existing breaker setup is important.

Where It Works Best
The Siemens HN3B500 500A molded case circuit breaker is best suited for existing electrical distribution equipment that calls for an HN3 frame, three-pole breaker, and matching interrupt rating requirements.
This breaker is a good fit for maintenance applications where the goal is to replace an existing unit while preserving the original electrical characteristics. Before installation, verify the complete specification match, including amperage, frame type, number of poles, voltage, and available fault current rating.
