This 3-pole switch unit is 15 inches wide and supports up to 350 HP at 600 VAC, pairing high-current protection with easy load isolation. It accepts Class H or Class K fuses natively and Class R fuses with the QMB4060R kit, delivering overcurrent and short-circuit protection, a load-to-source disconnect, and a clear open/close operating mechanism for safe, code-compliant panelboard protection.
