MT3350T - 350 Amp Trip Unit Description
MT3350T - 350 Amp Trip Unit
The MT3350T trip unit is a 350-amp, three-pole molded case circuit breaker accessory for use with compatible Type MDL and HMDL breakers. Designed around the Series C J-K frame configuration, this trip unit carries the T266 trip designation. It offers a clear option for maintaining your existing electrical equipment that requires these ratings and compatibility characteristics. For maintenance teams, electricians, and facility personnel working with legacy breaker installations, matching the details matters more than matching amperage alone: the breaker type, frame size, pole configuration, trip type, and physical dimensions should all match the equipment requirements.
Key Features and Benefits
- 350A amperage rating: Provides the specified trip-unit rating for compatible applications requiring 350 amps.
- Three-pole configuration: Matches equipment designed around a three-pole trip-unit arrangement.
- T266 trip type: Gives technicians an important identification point when matching a replacement to an existing breaker.
- MDL and HMDL compatibility: Specified for use with Type MDL and HMDL molded case circuit breakers.
- J-K frame configuration: Helps establish correct form and fit beyond simply matching the amperage rating.
- Series C designation: Identifies the applicable breaker series for more precise compatibility checks.

Where It Works Best
The MT3350T 350A trip unit is for existing and legacy electrical equipment using compatible MDL or HMDL molded case circuit breakers where the required configuration is a 350A, three-pole T266 trip unit for a Series C J-K frame. In replacement work, it's especially important to match the complete specification rather than selecting a trip unit based on amperage alone.
