The Square D MH36500 is a molded-case circuit breaker (MCCB) in Square D's MH frame, rated 500 A, 3-pole, 600 V AC, 25 kA SCCR. As a bolt-on MCCB, it is designed for installation in commercial and industrial panelboards and switchboards — not residential loadcentres. It is compatible with Square D I-Line and other MH-frame-rated panelboards and switchgear lineups that accept this frame size and bolt-on configuration.
Specific panelboard compatibility depends on bus rating, frame acceptance, and enclosure configuration. Send us your panelboard or switchboard model and we'll confirm fitment.
The MH36500 is part of Square D's MH frame series, rated at 25 kA SCCR at 600 V. If your application requires a higher interrupting rating (e.g., 65 kA or 100 kA), Square D offers other frame options in compatible sizes. Contact our team and we can help identify the right upgrade for your switchboard or panelboard.
Yes — the MH36500 is rated for 600 V AC, which aligns with Canadian distribution voltages (208 V, 347/600 V systems). As with any MCCB installation, it must be applied within its published ratings and installed per the CEC. If you need documentation such as CSA certification or technical data sheets, our team can assist.
