The MGA36350 SQUARE D circuit breaker is a robust 3-pole, 350 Amp unit designed for 600V applications with a interrupting rating of 18,000 Amperes. Ideal for industrial settings, it ensures reliable protection against overloads and short circuits. Trust this quality breaker to maintain safety and performance in your electrical systems.
The MGA36350 uses Square D's I-Line plug-in bus system, so it is designed for Square D I-Line panelboards and industrial switchboards that accept I-Line plug-in breakers. It is not compatible with Square D QO or Homeline residential loadcentres. If you're unsure whether your panel is I-Line compatible, send us the panelboard model number and we'll verify the fit.
The MGA36350 carries an 18,000A (18kA) interrupting rating at 600V. For most commercial and light industrial distribution systems this is adequate, but you should verify the available fault current (AFC) at the point of installation with your engineer or utility. If your system's AFC exceeds 18kA, a higher-rated breaker in the MGA frame may be required — contact us and we can help identify the right option.
The Square D MGA frame series is considered a legacy/hard-to-find product line. Northern Breaker Group specializes in obsolete and difficult-to-source breakers, and we maintain stock and sourcing networks specifically for units like the MGA36350.
