The Square D HJA frame (SQDHJA36025) is a moulded-case circuit breaker (MCCB) rated 25 A, 3-pole, 600 V AC. As an industrial-grade MCCB, it is designed to mount in Square D panelboards and switchboards that accept HJA-frame breakers — typically bolt-in commercial and industrial distribution equipment — and is not intended for residential loadcentres. It is well-suited to commercial and industrial applications including motor branch circuits, feeder protection, and light industrial distribution panels operating up to 600 V.
Specific panelboard compatibility depends on the exact enclosure and bus configuration. Send us your panelboard model and we'll confirm fitment.
The Square D HJA frame is rated for a standard interrupt capacity appropriate for commercial and industrial distribution — typically 14 kA or 25 kA symmetrical at 600 V AC depending on the specific variant. This generally meets CEC requirements for branch and feeder circuit protection in commercial installations. Contact us with your fault-current calculation and we can help confirm the right interrupt rating for your application.
Yes. The HJA-frame MCCB at 25 A, 3-pole, 600 V is commonly used for motor branch-circuit protection in commercial and light industrial settings. For motor loads, ensure the breaker's trip characteristics (thermal-magnetic) are compatible with the motor's locked-rotor current. We can help you verify suitability for your specific motor horsepower and starter combination — just reach out.
The Square D HJA frame is an older industrial MCCB series that can be difficult to source through standard supply channels.
