JA3070 70Amp Circuit Breaker

JA3070 - 70Amp Circuit Breaker

Replacing a breaker in older equipment can come down to a handful of very specific details. JA3070 is a 70-amp, 3-pole Type JA circuit breaker with a thermal-magnetic, non-interchangeable trip unit. Just as important, especially when you're trying to match an existing installation, are the physical dimensions: 5.50"W x 10.13"L x 3.94"D. Those measurements give you something concrete to compare before deciding whether the breaker is a fit. For compatible legacy equipment that calls for this JA configuration, the JA3070 provides the electrical ratings and physical format needed for a form, fit, and functional replacement.

Key Features and Benefits

• 70A, 3-pole configuration: Makes the basic electrical configuration easy to compare with the breaker being replaced.
• Type JA breaker: A key identifier when matching components in compatible legacy electrical equipment.
• Thermal-magnetic operation: Uses the specified thermal-magnetic trip design.
• Non-interchangeable trip unit: An important detail when checking the configuration of an existing breaker.
• Load-side terminals included: No guesswork about whether the stated configuration includes load-side terminals.
• 40°C rating: Another specification that can be checked directly against existing equipment requirements.

Material Compliance and Certifications

The available specifications for the JA3070 do not specify any UL, CSA, IEC, RoHS, REACH, or other material-compliance certification. Because that information wasn't supplied, it shouldn't be inferred from the breaker type or ratings.

Where It Works Best

The JA3070 makes sense when maintaining compatible existing or legacy equipment that specifically calls for a 70A, 3-pole Type JA breaker with a thermal-magnetic, non-interchangeable trip unit. It can be particularly useful in replacement situations where the goal is to preserve the required form, fit, and electrical configuration rather than change the equipment design.
