Product FAQs
6 answersWhich electrical distribution systems are compatible with the NENL34015?
This 3-pole breaker is engineered for integration into Square D enclosures, industrial control panels, and QED switchboards.
What are the conductor requirements for wiring the NENL34015?
The factory-installed lugs are rated for both copper and aluminum (Cu/Al) conductors. They accept wire sizes ranging from 14 AWG to 4 AWG.
What are the maximum fault current clearing capabilities for the NENL34015?
The interrupting capacity scales with the system voltage. It can safely clear up to 25kAIC at 240VAC, and up to 18kAIC when applied on 277VAC or 480VAC systems.
Under what other brands or series is the NENL34015 circuit breaker known?
This breaker is part of the Compact NSE100N family manufactured by Schneider Electric. It is frequently identified under the Merlin Gerin brand as well as Square D.
What specific fault conditions does the NENL34015 trip unit protect against?
The fixed thermal-magnetic trip unit provides LI protection. The long-time (L) function protects against sustained overloads, while the instantaneous (I) function clears severe short circuits.
How is the NENL34015 secured within a panel?
As a unit-mount circuit breaker with feed-thru connections, it bolts directly to the backpan or mounting surface of a control panel or switchboard rather than snapping onto a busbar.
