MGP36600 - 600 Amp Circuit Breaker

MGP36600 - 600 Amp Circuit Breaker

For replacement electrical equipment, a familiar catalog number helps, but the ratings and physical configuration must still match. The MGP36600 is a 600-amp, 3-pole circuit breaker for your electrical distribution applications, featuring an ET 1.0 basic electronic trip unit and a 600VAC, 50/60Hz operational voltage rating. For an existing or legacy installation, these concrete specifications make it easier to determine whether the breaker is a suitable form, fit, and functional replacement candidate. Solid construction lasts when the breaker is selected, installed, and maintained correctly.

Key Features and Benefits

• 600 Amp Rating: Provides a clearly defined 600A line-rated current for compatible electrical distribution equipment.
• 3-Pole Configuration: The three-pole arrangement is an important compatibility point when matching existing equipment.
• ET 1.0 Electronic Trip Unit: Uses a basic electronic ET 1.0 trip unit with manufacturer-specified protection settings.
• Adjustable Long-Time Pickup: The long-time pickup adjustment range is 300–800A, allowing this specification to match application requirements.
• Magnetic Tripping Current: Specified at 1,200–6,000A.
• 80% Continuous Current Rating: Clearly specified for accurate system evaluation.
• Line and Load Connections Identified: Uses terminal nuts on the line side and lugs on the load side, removing guesswork when comparing connection requirements.
• AL800M23K Load-Side Lugs: Accepts the specified aluminum or copper conductor range of 3 x 3/0 AWG to 3 x 500 kcmil.
• Integral Push-to-Trip Button: Provides a manual way to trip the circuit breaker.

Where It Works Best

The MGP36600 600A circuit breaker is best considered for compatible electrical distribution equipment requiring a 600A, 3-pole breaker, 600VAC operation, an ET 1.0 electronic trip unit, and the specified unit-mount configuration. It's also a practical replacement candidate where the existing equipment requires terminal nuts on the line side and AL800M23K lugs on the load side.

Fault-current requirements need to match the installation. Under UL 489, the MGP36600 carries interrupting ratings of 65kA at 240VAC, 35kA at 480VAC, and 18kA at 600VAC. Its physical footprint matters too: the breaker measures 8.27 inches wide, 12.86 inches high, and 8.05 inches deep, with a listed net weight of 29 pounds.
