The Square D HJA frame (SQDHJA36035) is a molded-case circuit breaker (MCCB) rated 5A, 3-pole, 600V in a bolt-on configuration. As an HJA-frame MCCB, it is designed for installation in Square D panelboards and switchboards that accept the HJA bolt-on frame — typically industrial and commercial distribution equipment, not residential loadcentres such as QO or Homeline panels.
Send us your panelboard model and we'll confirm compatibility before you order.
The Square D HJA-frame MCCBs carry a standard interrupt rating of 14kA at 600V (symmetrical). If your application requires a higher interrupt rating, Square D also offers the HJA frame in high-interrupt versions — contact our team and we can help identify the right fit for your fault-current requirements.
A 5A 3-pole rating in a 600V MCCB frame is a less common configuration, often needed for protecting small three-phase loads such as control transformers or instrumentation circuits. Northern Breaker Group specializes in obsolete and hard-to-find breakers — if the SQDHJA36035 is discontinued or out of stock elsewhere, contact us for availability at our Calgary, Edmonton, or Vancouver counters.
No — the HJA-frame is an industrial/commercial MCCB and is not compatible with Square D QO or Homeline residential loadcentres. Those panels require plug-in QO or Homeline-series breakers respectively. The SQDHJA36035 is intended for Square D bolt-on panelboards and switchboards designed to accept the HJA frame.
