The Square D QDL32150 is a bolt-on, 3-pole molded-case circuit breaker (MCCB) rated 150A / 250V. As a QDL-frame MCCB, it is designed for installation in Square D commercial and industrial panelboards and switchboards that accept QDL-series bolt-on breakers — not for use in residential QO or Homeline loadcentres.
Compatibility depends on your specific panelboard's bus configuration, available space, and interrupt rating requirements. Send us your panelboard model and we'll confirm fitment before you order.
The QDL frame is a larger, higher-capacity molded-case breaker series within the Square D lineup, rated for heavier commercial and industrial loads (such as this 150A / 250V unit). The QD series covers lighter-duty applications. The two frames are not interchangeable, so it's important to confirm your panelboard accepts QDL-frame bolt-on breakers before purchasing.
Northern Breaker Group specialises in sourcing obsolete and hard-to-find breakers across Canada. The QDL32150 may be available as a new-old-stock, reconditioned, or surplus unit depending on current inventory. Contact our Calgary, Edmonton, or Vancouver counters for availability and lead time — we'll provide a quote specific to your need.
A 3-pole 150A MCCB like the QDL32150 can serve as a main disconnect or branch breaker in an appropriately rated 3-phase commercial or industrial panelboard, provided the panel's bus rating, interrupt capacity, and voltage rating align with the breaker's specifications. Always verify with your electrical engineer or inspector, and ensure the installation meets applicable Canadian Electrical Code (CEC) requirements.
