JA3070W - 70Amp Circuit Breaker

JA3070W - 70Amp Circuit Breaker

When you're replacing a breaker in existing equipment, the small details can matter just as much as the amp rating. The JA3070W is a 70-amp, 3-pole Type JA circuit breaker with a thermal-magnetic, non-interchangeable trip unit and a 40°C rating. For existing and legacy equipment that specifically calls for this combination of Type JA frame, amperage, poles, trip configuration, and electrical ratings, the JA3070W provides a clearly defined option for form, fit, and functional replacement.

Key Features and Benefits

• 70-amp rating: Provides a clear starting point when matching the JA3070W against an existing breaker or equipment specification.
• 3-pole configuration: Identifies the required pole arrangement for compatible equipment.
• Type JA design: An important form-and-fit detail when sourcing a replacement for legacy systems that call for a Type JA breaker.
• Thermal-magnetic operation: Uses the specified thermal-magnetic trip design.
• Non-interchangeable trip unit: Helps define the exact breaker configuration and should be matched accordingly when replacing an existing unit.
• No terminals included: Makes the supplied configuration clear upfront, so terminal compatibility can be addressed separately.

Material Compliance and Certifications

The specifications provided specify any UL, CSA, IEC, RoHS, REACH, or other material compliance status. Those qualifications should not be assumed based solely on the breaker type, electrical ratings, or physical configuration.

Where It Works Best

The JA3070W is appropriate for compatible existing or legacy electrical equipment that specifically requires a 70A, 3-pole Type JA thermal-magnetic circuit breaker with a non-interchangeable trip unit. It is particularly relevant when the goal is to maintain the required form, fit, and function of the existing equipment rather than change its electrical configuration.
