Description

Designed to manage heavy electrical loads, the Square D KGL32100 provides 100A of robust overcurrent defense. It utilizes a thermal-magnetic trip mechanism for essential long-time and instantaneous (LI) protection. This legacy K-frame breaker mounts into Square D switchboards, motor control centers, and enclosures. Facilities upgrading infrastructure can substitute this with the PowerPacT HGL36100. It features a high 65kA interrupting rating at 240VAC to safely clear severe fault currents.

Product FAQs

6 answers
What is the recommended lug torque for the KGL32100 circuit breaker?

The standard AL250KD mechanical lugs on this breaker accept 6 AWG to 350 kcmil aluminum or copper wire and require a tightening torque of 300 lb-in (34 Nm).

Can the Square D KGL32100 be reverse fed?

Yes. Because this thermal magnetic circuit breaker does not have dedicated line and load markings, it is suitable for reverse feeding applications.

Is the KGL32100 still in active production by Square D?

No. The PowerPact K-frame is a legacy molded case circuit breaker series that has been phased out and superseded by newer PowerPact frames. However, replacement units remain available for maintaining existing switchboards and motor control centers.

Does this breaker provide ground fault protection?

No. The KGL32100 features standard thermal magnetic trip technology with long-time and instantaneous (LI) functions for overload and short-circuit protection. It does not include ground fault or equipment protection features.

What equipment is compatible with the KGL32100 breaker?

This unit mount K-frame breaker is designed for installation in compatible Square D switchboards, motor control centers, individual enclosures, and panelboards that accept legacy K-frame dimensions.

Are the trip settings adjustable on the KGL32100?

No. This specific breaker features fixed thermal and fixed magnetic trip settings. It does not offer adjustable dials for modifying the trip curve.
