MGL36600 - 600 Amp Circuit Breaker

MGL36600 - 600 Amp Circuit Breaker

Choosing the right MGL36600 circuit breaker for your existing installation means checking details that affect both electrical compatibility and physical fit. This 600 amp, 3-pole circuit breaker is rated for 600VAC at 50/60Hz and uses an ET 1.0 electronic trip unit with a 300–800A long-time pickup adjustment range. It is a unit-mount configuration with AL800M23K lugs on both the line and load sides, accommodating the specified aluminum or copper conductor range. For replacement work in compatible legacy electrical distribution equipment, these documented ratings, dimensions, lug configuration, and trip characteristics provide the practical information you need to determine whether the MGL36600 matches the existing application. Its solid construction is built to last when selected, installed, and maintained correctly.

Key Features and Benefits

• 600 Amp, 3-Pole Configuration: Rated at 600A with three poles for electrical distribution applications requiring this specific configuration.
• ET 1.0 Electronic Trip Unit: Uses an electronic basic ET 1.0 trip unit with a 300–800A long-time pickup adjustment range.
• 600VAC Operating Rating: Rated for 600VAC at 50/60Hz under UL 489.
• Line and Load Lugs: Lugs are provided on both sides of the breaker, a key detail when checking a replacement for form, fit, and function.
• Specified Conductor Range: AL800M23K terminals accommodate 3 x 3/0 AWG through 3 x 500 kcmil aluminum or copper conductors.
• 80% Continuous Current Rating: The MGL36600 has a manufacturer-specified continuous current rating of 80%.
• Push-to-Trip Function: An integral push-to-trip button lets you manually trip the breaker.
