Product FAQs

8 answers
What legacy circuit breaker does the JGA36175LC replace?

The JGA36175LC serves as a direct replacement for the discontinued Square D KA36175 circuit breaker. It fits into the same I-Line panelboards and switchboards while fulfilling the copper lug requirement.

What is the magnetic trip range for this 175A breaker?

The JGA36175LC features an adjustable magnetic trip with a low setting of 875A and a high setting of 1750A. The thermal overload protection is fixed at 175A.

What does the LC suffix indicate on the JGA36175LC catalog number?

The LC suffix specifies that the circuit breaker comes factory-equipped with copper mechanical lugs on the load side, rather than standard aluminum lugs.

Can I install this breaker in a standard QO or Homeline load center?

No. The JGA36175LC is a PowerPacT J-Frame breaker with an I-Line style plug-in connection. It is exclusively designed for use in Square D I-Line panelboards and switchboards.

What size and type of wire can the load lugs on the JGA36175LC accept?

The included copper lugs are designed to accept copper conductors only, ranging from 4 AWG to 4/0 AWG. Do not use aluminum wire with these specific lugs.

Is this breaker suitable for use in DC circuits?

Yes, the JGA36175LC is rated for use in DC applications up to 500VDC. It provides an interrupting capacity of 20kAIC at both 250VDC and 500VDC.

How do I adjust the magnetic trip settings on this breaker?

The magnetic trip settings can be adjusted using the dial located on the front of the trip unit. If the breaker is already installed in an I-Line panelboard, you must safely remove the deadfront to access the adjustment dial.

What does the LI trip function code mean on this breaker?

The LI designation indicates that the thermal-magnetic trip unit provides Long-Time (L) overload protection and Instantaneous (I) short-circuit protection.

    Even with the special Square D pricing we receive from our local vendors SuperBreakers pricing is often the lowest available. Fast shipping and great customer service.
