MA3700 - 700 Amp Circuit Breaker

MA3700 - 700 Amp Circuit Breaker

The MA3700 is a 700 amp, 3-pole thermal magnetic circuit breaker made for your electrical equipment that requires an MA-type breaker with an interchangeable trip unit. For replacement work, the important part is matching the details—not simply finding another 700A breaker. When the amperage, pole count, dimensions, A.I.C. ratings, trip-unit configuration, and terminal requirements match the application, the MA3700 can be considered a form, fit, and functional replacement candidate. Its solid construction is built to last when properly selected, installed, and maintained.

Key Features and Benefits

• 700 Amp Rating: Provides the specified 700A rating for electrical applications that call for this exact capacity.
• 3-Pole Configuration: Three poles provide another clear specification to check against the breaker being replaced.
• Thermal-Magnetic Operation: The MA3700 uses a thermal-magnetic circuit breaker configuration.
• Interchangeable Trip Unit: Supplied with an interchangeable trip unit, an important compatibility detail when matching existing MA equipment.
• Load-Side Terminals Included: This breaker includes load-side terminals.
• 40°C Rated: The supplied specifications identify the MA3700 as a 40°C-rated breaker.
• Built to Last: Solid construction suits its intended electrical application when the breaker is selected, installed, and maintained correctly.

Material Compliance and Certifications

The available specifications for the MA3700 did not include specific agency listings, certifications, or material-compliance information. For that reason, do not assume UL, IEC, RoHS, REACH, or other compliance status.

Where It Works Best

The MA3700 700A circuit breaker is best considered for existing electrical equipment that specifically requires a 700-amp, 3-pole MA thermal magnetic breaker with an interchangeable trip unit. This is especially relevant for maintenance and replacement situations where the goal is to preserve the required form, fit, and electrical function.
