MDL3400 - 400 Amp Circuit Breaker Description
MDL3400 - 400 Amp Circuit Breaker
When you're replacing a breaker in existing equipment, the details matter more than marketing language. The MDL3400 is a 400 amp, 3-pole MDL thermal-magnetic circuit breaker with an interchangeable trip unit, a 40°C rating, and an HACR rating. For legacy electrical equipment that calls for this catalog number and matching electrical characteristics, it can be considered a form, fit, and functional replacement candidate.
Key Features and Benefits
- 400 Amp, 3-Pole Configuration: Rated at 400A with three poles for applications requiring this specific MDL configuration.
- Thermal-Magnetic Trip: The MDL3400 uses the specified thermal-magnetic trip design.
- Interchangeable Trip Unit: Its interchangeable trip unit is an important configuration detail when matching the breaker to existing equipment.
- Load Terminals Included: The supplied product information specifically identifies load terminals as included. Line terminals are not listed as included and should not be assumed.
- 40°C Rated: Temperature rating is clearly identified for easier specification matching.
- HACR Rated: The MDL3400 is specified as HACR rated.

Material Compliance and Certifications
The available specifications identify the MDL3400 as HACR rated. No additional certification or material-compliance information, including UL, IEC, RoHS, or REACH status, was supplied for this exact part number. Rather than assuming information from another MDL breaker applies here, verify any additional certification requirements specifically for the MDL3400.
Where It Works Best
The MDL3400 400 amp circuit breaker is best considered for compatible existing and legacy electrical equipment that requires its particular MDL configuration. For replacement work, check more than the amperage alone. The existing application should match the 400A rating, three-pole configuration, thermal-magnetic trip, interchangeable trip unit, 40°C rating, and required voltage and interrupting capacity.
