Product FAQs
4 answersHow much mounting space does the NE361200LS require in an I-Line panelboard?
As a 1200A N-frame I-Line circuit breaker, it requires 15 inches of branch mounting space on the bus.
Will this breaker work in a standard QO or NQ panelboard?
No. The NE361200LS features an I-Line style plug-in connection and is exclusively compatible with Square D I-Line panelboards and switchboards designed to accept N-frame breakers.
What does the LS designation mean on the NE361200LS trip unit?
The LS indicates that the breaker is equipped with an electronic trip unit featuring adjustable Long-Time and Short-Time trip functions. This allows panel builders to precisely coordinate the breaker with other overcurrent devices in the system.
Is the NE frame still the current standard for 1200A Square D breakers?
The NE frame is a legacy N-frame circuit breaker. While the PowerPact P-frame is the modern equivalent for 1200A applications, the NE361200LS is often required as a direct, drop-in replacement for existing N-frame I-Line panel spaces.
