MDL3800L - 800 Amp Circuit Breaker

MDL3800L - 800 Amp Circuit Breaker

For replacement work, terminal configuration can be just as important as amperage and physical size. The MDL3800L is an 800 amp, 3-pole MDL thermal-magnetic circuit breaker with an interchangeable trip unit, and this particular configuration includes both line and load terminals. When your electrical, physical, and terminal requirements match, the MDL3800L can be considered a form, fit, and functional replacement candidate for compatible legacy electrical equipment. Its solid construction is built to last when selected, installed, and maintained correctly.

Key Features and Benefits

• 800 Amp, 3-Pole Configuration: Provides the specified 800A rating across a three-pole configuration for equipment requiring these exact characteristics.
• Thermal-Magnetic Protection: The MDL3800L uses the specified thermal-magnetic trip design.
• Interchangeable Trip Unit: The breaker includes an interchangeable trip unit, which is important when matching an existing MDL installation.
• Line and Load Terminals Included: This model includes both terminal sets, helping distinguish the MDL3800L from similar configurations where only load terminals are specified.
• 40°C Rated: The supplied specifications identify this breaker as 40°C rated.
• HACR Rated: HACR rating is specifically listed for the MDL3800L.

Where It Works Best

The MDL3800L 800 amp circuit breaker is a practical replacement candidate for compatible existing and legacy electrical equipment that requires an MDL-type, 3-pole thermal-magnetic circuit breaker with an interchangeable trip unit. Matching should include the 800A rating, voltage and AIC requirements, 40°C rating, HACR designation, physical dimensions, and line-and-load terminal configuration.
