The SQDHLP36050 is a Square D HLP-frame moulded-case circuit breaker (MCCB) — a commercial/industrial-grade device rated 50 A, 3-Pole, 600 V. As an MCCB, it is designed to mount in commercial panelboards and industrial switchboards that accept HLP-frame bolt-on breakers, not in residential loadcentres. It is well-suited for motor branch circuits, feeder protection, and general industrial distribution at 600 V AC.
Specific panelboard compatibility depends on the cubicle/interior design of your switchboard or panelboard. Send us your panelboard model and we'll confirm fitment before you order.
Yes. The SQDHLP36050 is rated 600 V AC, 3-Pole, 50 A, making it fully suitable for Canadian industrial distribution systems operating at 600 V — the standard utilization voltage in Canadian commercial and industrial facilities. Its thermal-magnetic mechanism provides both overload and short-circuit protection per CSA requirements.
The Square D HLP-frame series is considered obsolete/discontinued, which can make sourcing a challenge. Northern Breaker Group specializes in exactly these hard-to-find and obsolete breakers. Contact us or visit one of our Calgary, Edmonton, or Vancouver counters for current stock availability — we recommend reaching out early to avoid project delays.
Yes, a 3-pole, 50 A, 600 V thermal-magnetic MCCB like the SQDHLP36050 is commonly used for motor branch-circuit and feeder protection in industrial settings. Always verify the breaker's interrupt rating and motor FLA against your specific application requirements, and consult the Canadian Electrical Code (CEC) Section 28 for motor circuit sizing rules.
