Product FAQs
6 answersWhat does the 1027 suffix indicate on the KAL362501027?
The 1027 suffix means this circuit breaker is equipped with a factory-installed 24VDC shunt trip. This allows the breaker to be tripped remotely by applying a 24VDC control signal.
Is the KAL362501027 designed for plug-on I-Line panels or unit mounting?
This is a unit-mount, feed-thru circuit breaker. It is designed to be bolted directly to the mounting surface or panel and is not compatible with plug-on I-Line switchboards.
What is the modern replacement for the legacy KAL362501027?
The Square D K-Frame series is a legacy product. When upgrading or replacing this breaker, the modern equivalent is a 250A PowerPact J-Frame circuit breaker equipped with a 24VDC shunt trip accessory.
Can the thermal and magnetic trip settings be adjusted on this breaker?
The KAL362501027 features a thermal-magnetic trip unit with a fixed thermal, long-time setting and an adjustable magnetic, instantaneous trip setting. This allows you to fine-tune the short-circuit protection based on your specific load requirements.
Can the KAL362501027 be used in DC applications?
Yes, this breaker is rated for use in DC systems up to 250VDC, where it provides a 10kA interrupting capacity. When used in DC applications, specific wiring configurations across the poles may be required per manufacturer guidelines.
Does the KAL362501027 provide ground fault protection?
No, this breaker is equipped with a standard thermal-magnetic trip unit for overload and short-circuit protection. It does not include integrated ground fault protection for equipment or personnel.
