MGL36800 - 800 Amp Circuit Breaker

MGL36800 - 800 Amp Circuit Breaker

The MGL36800 is an 800 amp, 3-pole circuit breaker built to meet specific electrical and physical requirements when matching equipment to your existing distribution system. For replacement work, those details matter as much as the catalog number: pole count, voltage, interrupting capacity, trip configuration, terminals, conductor requirements, and physical size must match the application.

Key Features and Benefits

• 800 Amp, 3-Pole Configuration: Rated at 800A with three poles for compatible electrical distribution applications.
• ET 1.0 Electronic Trip Unit: Electronic basic trip technology provides a clearly specified trip configuration for accurate replacement matching.
• Long-Time Pickup Range: The long-time pickup adjustment range is 300–800A.
• Specified Magnetic Tripping Current: Manufacturer data lists a 1,600–8,000A magnetic tripping current.
• Line and Load Lugs Included: Lug connections are provided on both sides, removing ambiguity about the supplied terminal configuration.
• AL800M23K Terminals: Accepts the specified 3 x 3/0 AWG through 3 x 500 kcmil aluminum or copper conductors.
• 80% Continuous Current Rating: Clearly identified in the manufacturer's specifications.
• Integral Push-to-Trip Function: The breaker cover includes a push-to-trip button for manual tripping.

Where It Works Best

The MGL36800 800A circuit breaker suits compatible electrical distribution equipment that calls for an 800-amp, 3-pole, 600VAC breaker with an ET 1.0 electronic trip unit and an 80% continuous current rating. It can be particularly useful when replacing an existing breaker where maintaining the correct electrical ratings, trip characteristics, lug arrangement, conductor capacity, and physical footprint is essential.
