Product FAQs
5 answersWhat panelboards accept the IL34300 circuit breaker?
The IL34300 is designed specifically for installation in Square D I-Line panelboards and switchboards. It is not compatible with standard load centers or non-I-Line commercial panels.
How is the IL34300 mounted within a panel?
It utilizes a plug-on mounting system designed for the I-Line busway. The breaker plugs directly into the bus stack, which provides a secure mechanical and electrical connection without the need for individual cable terminations on the line side.
How does the I-Limiter design benefit the electrical system?
The I-Limiter series provides current-limiting capabilities that restrict the peak let-through current during a fault. This helps prevent extensive thermal and mechanical damage to downstream equipment and wiring.
What is the modern replacement for the legacy IL34300 breaker?
The IL34300 is a legacy Square D component. When upgrading or replacing this unit in modern systems, electricians typically transition to the Square D PowerPact L-frame series, provided the panelboard configuration supports the newer footprint.
What protection functions are provided by the trip unit on this breaker?
The breaker features a fixed thermal-magnetic trip unit that delivers long-time protection for standard overloads and instantaneous protection (LI) to quickly clear severe short-circuit faults.
