Square D KAL36100 Molded Case Circuit Breaker

No. The KAL36100 is a unit-mount circuit breaker configured for feed-thru installations. It bolts directly to the mounting surface and requires mechanical lug connections, whereas I-Line panels require breakers equipped with plug-on bus connectors.

While the thermal overload (long-time) limit is fixed at 100A, the instantaneous magnetic trip setting is adjustable. This allows electricians to fine-tune the short-circuit response threshold, preventing nuisance tripping when powering loads with high inrush currents like large motors or transformers.

When equipped with standard AL250KA mechanical lugs, the KAL36100 accepts either aluminum or copper conductors sized from 4 AWG to 350 kcmil. Always torque lug connections to the manufacturer's specified values during installation.

Yes, the KAL frame is a legacy product line discontinued by Schneider Electric. Sourcing a direct KAL36100 replacement allows you to match the existing panel footprint and buswork precisely without fabricating custom adapter brackets.

Schneider Electric recommends the PowerPact H-Frame (such as part number HGL36100) as the contemporary replacement for a 100A K-Frame. Because the modern PowerPact footprint is smaller, retrofitting will require specific adapter hardware and panel filler plates.

Yes. This circuit breaker carries an HACR rating, indicating it is certified to safely handle the group motor inrush currents associated with commercial heating, air conditioning, and refrigeration systems.

Yes. In addition to its 600VAC rating, this breaker is certified for direct current systems up to 250VDC with a 10kA interrupting capacity, providing overcurrent protection for industrial DC drives and control circuits.
