MA3350 - 350 Amp Circuit Breaker

MA3350 - 350 Amp Circuit Breaker

The MA3350 is a 350-amp, 3-pole MA thermal-magnetic circuit breaker for your compatible electrical equipment that requires this specific combination of current rating, pole configuration, trip-unit style, and physical dimensions. Rated for 40°C and equipped with an interchangeable trip unit, the MA3350 offers clear specifications that make it easier to evaluate for existing and legacy electrical systems.

Key Features and Benefits

• 350 Amp Rating: Provides the specified 350A current rating for compatible electrical applications.
• 3-Pole Configuration: The three-pole arrangement is an important specification when matching an existing circuit breaker.
• MA Type: Clearly identified as an MA-type breaker for easier part and equipment compatibility checks.
• Thermal Magnetic Operation: Uses the specified thermal magnetic circuit breaker configuration.
• Interchangeable Trip Unit: Supplied with an interchangeable trip unit, a key detail when evaluating the MA3350 as a replacement.
• 40°C Rated: The breaker carries the specified 40°C temperature rating.
• Load-Side Terminals Included: The breaker includes load-side terminals, helping identify the supplied terminal configuration.

Where It Works Best

The MA3350 350A 3-pole circuit breaker is best considered for compatible existing and legacy electrical equipment that calls for an MA-type thermal magnetic circuit breaker with an interchangeable trip unit and a 40°C rating. It is particularly useful in replacement situations where retaining the required form, fit, and electrical characteristics is the priority rather than changing the equipment configuration.
