The SQDHDL36020 is a high-quality Square D 3-pole circuit breaker designed for reliable performance in demanding applications. With a current rating of 20A and a voltage capacity of 600V, it ensures optimal protection for your electrical systems. Perfect for industrial and commercial use, it combines durability with efficiency.
The Square D HDL frame is a heavy-duty molded-case frame rated for industrial 600V applications. The SQDHDL36020 carries a 20A trip rating within that frame, meaning it provides a lower trip point while still offering the robust interrupting capacity and physical size of the full HDL frame — useful where a high interrupting rating is required on a lightly loaded 20A circuit.
Yes. The HDL-frame MCCB at 600V 3-pole is well-suited for motor branch-circuit protection in commercial and industrial settings, provided the motor's full-load current and starting characteristics are within the breaker's trip curve. Always verify with your engineer or electrician that the trip class and curve match your motor load per CSA/NEC requirements.
Availability can vary as Square D periodically updates its MCCB product lines. Northern Breaker Group specialises in obsolete and hard-to-find breakers across Canada, so even if this unit is no longer in current production, we can often source new-old-stock or factory-reconditioned units.
