The HGL36030 is a reliable Square D 3-Pole Circuit Breaker designed for maximum performance in demanding electrical applications. With a rated current of 30 Amps and a voltage capacity of 600V, this breaker ensures optimal circuit protection and safety. Ideal for commercial and residential use, it’s a trustworthy component for any system.
The HGL36030 is an HGL-frame molded-case circuit breaker (MCCB) designed for bolt-on mounting in Square D commercial and industrial panelboards and switchboards rated for 600V and compatible with the HGL frame. It is not designed for residential plug-on loadcentres. Send us your enclosure model and we'll confirm compatibility.
The Square D HGL-frame series is a legacy MCCB line that has largely been superseded by newer Square D MCCB frames. Northern Breaker Group specializes in sourcing obsolete and hard-to-find breakers — contact our Calgary, Edmonton, or Vancouver counters for current stock availability or to request a quote.
The HGL36030 is rated at 18kA interrupting capacity at 600V. It should only be used as a replacement where the available fault current at the point of installation does not exceed 18kA. If your system has a higher available short-circuit current, you will need an HGL-frame breaker with a higher interrupt rating. Always verify with a qualified electrician and consult the panelboard's nameplate before substituting.
