Product FAQs
6 answersWhat does the "-1021" suffix indicate on the KIL36200-1021 catalog number?
The "-1021" suffix designates that the circuit breaker comes with a factory-installed 120-240V AC shunt trip accessory, which allows the breaker to be tripped remotely.
What does the "I" in the KIL frame designation mean?
The "I" signifies that this is a current-limiting circuit breaker. It is engineered to restrict let-through energy during a fault, providing enhanced protection for downstream electrical equipment.
What wire sizes are supported by the standard lugs on this breaker?
The factory line and load lugs accept conductor sizes ranging from 4 AWG to 350 kcmil and are rated for both aluminum and copper wire.
Is the KIL36200-1021 part of a current production series?
No, the KIL is a legacy Square D K-frame breaker. When upgrading or replacing equipment in modern systems, the PowerPact J-frame series is the manufacturer recommended replacement path.
How is the trip unit configured on this breaker?
This breaker utilizes a thermal-magnetic trip unit featuring a fixed thermal element for long-time overload protection and an adjustable magnetic element for instantaneous short-circuit protection.
What equipment is compatible with this unit-mount breaker?
This feed-thru breaker is designed to be fastened securely into compatible Square D enclosures, switchboards, and motor control centers.
