Circuit Breakers for Distribution Panel and Control PanelFA/FAU/FHU Series

01

• External dimensions are identical for both molded case and earth leakage circuit breakers. (The NV-FAU three-phase breaker with earth leakage protection also has identical external dimensions.)
• The 30A and 50A frame models also have identical external dimensions.
• 2-pole and 3-pole products are available.

02

• The vertical dimension of the circuit breaker is consistent with the vertical dimension of the socket for miniature relays at 72mm.
• Can be mounted side-by-side with miniature relays, electromagnetic contactors, etc. between the same ducts, which eliminates wasted space.

03

• The terminal structure allows for back-side wiring.
• Terminal covers (RTC) for surface plate mounting are available. These covers can be used for safeguarding against electric shock when wiring on the back side.

04

• Surface plate mounting is possible, eliminating the need to tighten nuts from the rear. (Use M5 x 0.8 x 30 screws.)

01

• The FHU is a high breaking capacity product of the FA series with JIS-compliant modular dimensions that can handle up to 100A of rated current.
• Molded case circuit breakers and molded case circuit breakers with earth leakage protection have identical external dimensions.
  (The NV-FHU three-phase molded case circuit breaker with earth leakage protection also has identical external dimensions.)
• 2-pole and 3-pole products are available.
  (The NF100-FHU and NV100-FHU are only available as 3-pole products.)

02

• Motor circuit protection characteristics are standard. Rated current for motor protection is set for NF50-FHU and NV50-FHU models.
• We also offer large terminal covers.
