MDL3700 - 700 Amp Circuit Breaker

MDL3700 - 700 Amp Circuit Breaker

The MDL3700 is a 700 amp, 3-pole MDL thermal-magnetic circuit breaker intended for applications where the electrical ratings, trip configuration, and physical size match your existing equipment. It features an interchangeable trip unit, a 40°C rating, and HACR rating. For compatible existing or legacy electrical equipment requiring these characteristics, the MDL3700 can serve as a form, fit, and functional replacement candidate when all relevant specifications match. Solid construction is built to last when the breaker is selected, installed, and maintained correctly.

Key Features and Benefits

• 700 Amp Rating: Rated at 700A for compatible electrical equipment requiring this exact amperage.
• 3-Pole Configuration: The three-pole arrangement is an essential specification to check when matching an existing MDL breaker.
• Thermal-Magnetic Circuit Breaker: Uses the specified thermal-magnetic trip configuration for its intended electrical application.
• Interchangeable Trip Unit: The MDL3700 has an interchangeable trip unit, an important characteristic when verifying a replacement.
• Load Terminals Included: This particular MDL3700 configuration includes load terminals. Line terminals are not identified as included in the supplied specifications.
• 40°C Rated: The supplied specifications identify the breaker as 40°C rated.
• HACR Rated: HACR rating is specifically listed for the MDL3700.

Where It Works Best

The MDL3700 700 amp circuit breaker is best considered for compatible existing and legacy electrical equipment that calls for a 700A, 3-pole MDL thermal-magnetic circuit breaker with an interchangeable trip unit. Match more than the catalog family or amperage alone. The required interrupting rating, voltage, physical dimensions, trip configuration, temperature rating, and terminal arrangement must match the application.
