JA3100 - 100Amp Circuit Breaker

JA3100 - 100Amp Circuit Breaker

The JA3100 gives you a clear set of specifications to work from when matching a breaker to existing electrical equipment. This 100-amp, 3-pole Type JA circuit breaker uses a thermal-magnetic, non-interchangeable trip unit and carries a 40°C rating. For compatible legacy systems that specifically call for this Type JA configuration, the goal is simple: verify the form, fit, ratings, and trip arrangement before installation. These products are built to last, while proper application still depends on confirming that every relevant specification matches the equipment requirements.

Key Features and Benefits

• 100A current rating: Provides the specified amperage for equipment designed around a 100-amp breaker.
• Three-pole configuration: Gives buyers an essential compatibility point when matching an existing three-pole breaker.
• Type JA: Clearly identifies the breaker type for form-and-fit comparison with existing equipment.
• Thermal-magnetic operation: Uses the specified thermal-magnetic trip design.
• Non-interchangeable trip unit: Helps distinguish the required trip configuration when checking replacement compatibility.
• Load-side terminals included: The supplied configuration includes load-side terminals.

Material Compliance and Certifications

The supplied specifications do not provide specific UL, CSA, IEC, RoHS, REACH, or other certification or material compliance information for the JA3100. These should not be inferred from the Type JA designation or electrical ratings. If a particular listing, standard, or material requirement applies to the installation, verify it using the breaker markings and applicable manufacturer documentation.

Where It Works Best

The JA3100 100A circuit breaker is appropriate for compatible existing and legacy electrical equipment that specifically requires a 3-pole Type JA breaker with a thermal-magnetic, non-interchangeable trip unit. Because load-side terminals are included, that configuration should also be checked against the equipment and existing installation rather than assumed to be interchangeable with another JA variant.
