JJ3B150 - 150Amp Circuit Breaker Description
JJ3B150 - 150Amp Circuit Breaker
The JJ3B150 is a 150A, three-pole molded-case circuit breaker for applications where matching your existing JJ3-frame equipment is the priority. Its electrical ratings provide clear checkpoints for identifying a replacement: 42 kA at 240 VAC, 30 kA at 480 VAC, and 22 kA at 600 VAC. The JJ3B150 is built to last and is a practical form, fit, and functional replacement when its frame, dimensions, electrical ratings, and other specifications match the existing system.
Key Features and Benefits
- 150A current rating: Provides a clear starting point when matching an existing breaker.
- Three-pole configuration: Intended for equipment requiring the same three-pole arrangement.
- JJ3 frame: Helps identify physical and equipment compatibility for replacement applications.
- Molded case circuit breaker: Matches the product construction specified for the JJ3B150.
- 40°C rating: Provides an additional specification to confirm against the requirements of the existing installation.

Material Compliance and Certifications
No specific UL, CSA, IEC, RoHS, REACH, or other material-compliance certifications were provided in the available product specifications. These certifications should not be assumed based solely on the breaker type or electrical ratings. If a particular certification is required for the installation, verify it on the product label or in the applicable manufacturer documentation.
Where It Works Best
The JJ3B150 is best suited to compatible existing and legacy electrical equipment that requires a 150A, three-pole molded-case circuit breaker with the same JJ3 frame characteristics. Its 240VAC, 480VAC, and 600VAC AIC ratings make voltage and interrupting capacity especially important parts of the compatibility check.
