The NEELE NLEM1 Series is a thermal-magnetic molded case circuit breaker designed for low-voltage power distribution systems.
It provides reliable overload and short-circuit protection, with current ratings from 125A to 1600A, 3P and 4P configurations, and multiple breaking-capacity grades for different distribution requirements.
L Grade — Standard breaking capacity
M Grade — Higher breaking capacity
H Grade — High breaking capacity
Your existing product document classifies these approximately as 35kA / 50kA / 70kA+.

Industrial power distribution, commercial buildings, infrastructure, main distribution panels, power distribution cabinets and other low-voltage distribution systems.
What protection does the NLEM1 provide?
The NLEM1 provides overload and short-circuit protection through a thermal-magnetic trip mechanism.
What pole configurations are available?
3P and 4P versions are available.
What current range is available?
The NLEM1 Series covers 125A to 1600A.
What do L, M and H mean?
L, M and H indicate different breaking-capacity grades for different system fault-current requirements.
What does /3300 mean?
It indicates a 3-pole thermal-magnetic trip configuration in the standard base version.
What does /4300 mean?
It indicates a 4-pole thermal-magnetic trip configuration in the standard base version.
Does NLEM1 include leakage protection?
No. The standard NLEM1 is a thermal-magnetic MCCB without leakage protection. Your existing product system separates the leakage-protection type into another series.
