Product FAQs

5 answers
What panelboards are compatible with the Square D Q232110?

This breaker is designed exclusively for use in Square D I-Line panelboards and switchboards. It features an I-Line style plug-in connection for ABC phase configurations, allowing for efficient installation.

What is the modern replacement for the legacy Q232110 circuit breaker?

The Q232110 is a legacy Q2-series breaker that has been superseded by the PowerPact Q-frame series. The direct modern replacement is the QBA32110, which matches the 110A, 3-pole, 10kAIC rating and I-Line mounting.

What wire sizes and conductor materials are accepted by the Q232110 terminals?

The terminal lugs accept wire gauges ranging from 4 AWG to 300 kcmil. They are rated for use with both aluminum and copper conductors.

How does the thermal-magnetic trip unit on the Q232110 operate?

The breaker features a fixed thermal-magnetic trip mechanism with long-time and instantaneous (LI) functions. The thermal component responds to sustained overloads, while the magnetic component reacts immediately to short-circuit faults.

What are the physical dimensions of the Q232110 Q-frame breaker?

The breaker measures approximately 7.88 inches high, 4.5 inches wide, and 4.31 inches deep. These dimensions are critical when verifying fitment in older I-Line distribution equipment.
