JA3100W - 100Amp Circuit Breaker

JA3100W - 100Amp Circuit Breaker

When you're replacing a breaker in older equipment, amperage is only one piece of the puzzle. JA3100W is a 100A, 3-pole Type JA circuit breaker with a thermal-magnetic, non-interchangeable trip unit. For compatible legacy systems calling for the JA3100W configuration, the goal is simple: match the electrical ratings, trip arrangement, dimensions, and terminal requirements as closely as the application requires. These products are built to last, but proper selection still begins with getting those details right.

Key Features and Benefits

• 100A, 3-pole configuration: Gives you two of the most important specifications to check against the existing breaker.
• Type JA breaker: Helps narrow the match when equipment documentation or the existing breaker calls for a Type JA breaker.
• Thermal-magnetic operation: Uses the thermal-magnetic trip design identified in the supplied specifications.
• Non-interchangeable trip unit: An important configuration detail when checking a replacement against existing equipment.
• Terminals are not included; worth confirming early to avoid assumptions about the supplied configuration.

Material Compliance and Certifications

No specific UL, CSA, IEC, RoHS, REACH, or other certification or material-compliance information was provided for the JA3100W. Those qualifications should not be inferred from the breaker type or electrical ratings. If a particular certification or material requirement is necessary for the installation, confirm it using the product markings and applicable manufacturer documentation.

Where It Works Best

The JA3100W is a practical match to consider when maintaining compatible existing or legacy equipment that specifically requires a 100A, 3-pole Type JA circuit breaker with a thermal-magnetic, non-interchangeable trip unit. Because terminals are not included, that part of the installation should be checked separately rather than assumed from the catalog number.
