Description

Operating as a core component in industrial power distribution, this 90A breaker provides essential long-time and instantaneous protection. It mounts via line and load lugs into Square D enclosures, switchboards, and motor control centers. When modernizing older infrastructure, this legacy K-Frame model is superseded by the PowerPact H-Frame HDL26090. With a 42kA interrupting rating at 240VAC, the unit incorporates an adjustable magnetic trip to accommodate specific inrush currents.

Product FAQs

6 answers
What is the adjustable magnetic trip range for the KAL26090 circuit breaker?

The instantaneous magnetic trip on this 90A breaker can be adjusted from a low setting of 450A to a high setting of 900A.

Is the Square D KAL26090 still in active production?

No, the KAL series is a legacy K-frame molded case circuit breaker. For new installations or modernizations, it is typically superseded by the Square D PowerPact H-frame series, such as the HDL26090, though retrofit kits may be required.

Can the KAL26090 be reverse fed?

Yes. Standard thermal magnetic K-frame circuit breakers like the KAL26090 do not have designated line and load terminals, making them suitable for reverse feeding in bidirectional power applications.

What lug kit is standard for the KAL26090 breaker?

The AL250KA lug kit is the standard terminal kit used for Square D K-frame circuit breakers up to 250 amps. It accepts 4 AWG to 350 kcmil aluminum or copper wire.

Does the KAL26090 provide ground fault or arc fault protection?

No. This is a standard thermal magnetic circuit breaker providing long-time overload and instantaneous short-circuit protection. It does not include integrated equipment ground fault or arc fault capabilities.

What safety precautions apply when adjusting the magnetic trip on the KAL26090?

Adjustments to the magnetic trip dial should only be performed by a qualified electrician when the breaker is de-energized. The setting must coordinate with the downstream load and short-circuit calculations to ensure proper equipment protection.
