Product FAQs
6 answersWhat equipment is the LCL36300 compatible with?
This unit-mount breaker bolts directly into Square D switchboards, motor control centers, and individual enclosures.
Does this breaker mount onto an I-Line panelboard?
No. The LCL36300 features a bolt-on connection for unit mounting. It is not compatible with I-Line plug-on panelboards.
What does the C in the LCL frame designation indicate?
The C indicates that this is a current-limiting circuit breaker. It is designed to minimize let-through energy during a fault to protect downstream equipment.
What wire sizes do the factory-installed lugs accept?
The lugs accept either one 1 AWG to 600 kcmil wire or two 1 AWG to 250 kcmil wires per phase. Both aluminum and copper conductors are supported.
How is the trip unit configured on this breaker?
It features a thermal-magnetic trip unit with fixed thermal protection for long-time overcurrents and an adjustable magnetic trip for instantaneous short-circuit protection.
What is the modern replacement for the legacy LCL36300?
The LCL frame is a legacy molded case circuit breaker. It can typically be replaced by the modern PowerPact L-frame series, such as the LJL36400U31X.
