Note 1: When using a 3-contact earth leakage breaker for 1 ø 2 W, do not use the center contact. Connect the left and right contacts.
When using for 1 ø 3 W, connect the center contact to a neutral wire. (UL cannot use 1 ø 3 W.)
Note 2: 0.1 for UL1053.
Note 3: The rated breaking capacity is 1.5 kA for parts with 5 A rated current.
Note 4: The rated breaking capacity is 1.5/1 kA for parts with 5 A rated current.
Note 5: The customer must provide the mounting screws. For details, please refer to the catalog.
Note 6: Can install surface plate without tightening nuts from the back. (The customer must provide the mounting screws M5 × 0.8 × 30) Here, terminal screws can be tightened from the back of the breaker.
Note 7: Only included when an alarm switch (AL) is attached. (Excludes NF30-FAU and NF50-FAU SHT+AL)
Note 8: For rated current for motor protection, only current sensitivities of 30 mA or 50 mA can be manufactured.
