Product FAQs
8 answersWhat does the "SA" suffix mean in the HJA36030SA catalog number?
The "SA" suffix indicates that this breaker includes a factory-installed 120VAC shunt trip, allowing for remote tripping of the circuit breaker.
Can I install the HJA36030SA in a standard QO or Homeline load center?
No, the HJA36030SA is an I-Line style plug-in molded case circuit breaker designed exclusively for Square D I-Line panelboards and switchboards. It will not fit in standard residential QO or Homeline load centers.
Are lugs included on both the line and load sides of the HJA36030SA?

How is the 120VAC shunt trip wired on the HJA36030SA?
The factory-installed shunt trip includes control wire leads that exit the breaker. These leads must be connected to your external 120VAC control circuit to enable remote tripping.

How can I manually test the mechanical tripping mechanism of the HJA36030SA?
The breaker features an integral push-to-trip button on the front cover. Pressing this button manually trips the breaker, allowing you to verify the mechanical operation of the trip mechanism.
