This unit is new surplus in its original packaging, backed by a one-year operational guarantee from ESP.

Note the shunt trip. The 1037 suffix denotes a factory-installed shunt trip with a 277/480V coil, allowing the breaker to be tripped remotely from a control circuit — used for emergency power-off, fire alarm interlocks, ground fault relay tripping, and remote shutdown. Coil voltage is configuration-specific: the 1021 carries a 120V coil and the 1027 a 24V coil. The plain KAL36150 has no shunt trip and is not a substitute where one is required.

The Square D K-frame line is legacy product. ESP stocks new surplus and tested reconditioned units for panelboards and switchboards still in service, backed by a one-year operational guarantee.

More Details

The Square D KAL361501037 is a three-pole K-frame molded case circuit breaker rated 150 amperes at 600V AC, with a standard interrupting capacity of 25 kA at 480V and thermal-magnetic LI protection. Feed-thru connection with line and load side lug terminals accepting 4 AWG through 350 MCM conductors.

This unit is new surplus in its original box. On legacy K-frame product, where most available inventory has been pulled from service and reconditioned, unused stock in original packaging is uncommon — particularly in an accessory-equipped configuration.

The 1037 suffix denotes a factory-installed shunt trip with a 277/480V coil. A shunt trip opens the breaker remotely from a control circuit rather than by hand at the panel, which is how emergency power-off systems, fire alarm interlocks, ground fault relays, and remote shutdown schemes are implemented. Shunt trips are installed at the factory into a dedicated pole cavity and are not straightforward to add later, so a specification calling for one cannot be met with a plain KAL36150. Confirm the coil voltage matches the control circuit before ordering — related catalog numbers carry different coils.

New surplus with a one-year operational guarantee from ESP.

What is "surplus new"?

Surplus new means the item has never been installed or put into service. It may not arrive in its original packaging, but it has never been used.

What does "reconditioned" mean?

Reconditioned items have been inspected, cleaned, and tested to confirm they operate to the manufacturer's original specifications. Every reconditioned item we sell carries a one-year operational guarantee.

How fast will my order ship?

In-stock orders placed before 12pm PST usually ship the same business day via UPS, with tracking provided.
