Features

  • - Complete range of UL 489 listed DIN rail mounted miniature circuit breakers up to 40A current rating
  • - Standard ratings of 10 kAIC up to 277/480 Vac
  • - Select amperages available at 14 kAIC up to 277/480 Vac and 10 kAIC up to 125 Vdc per pole
  • - Current limiting design provides fast short-circuit interruption that reduces the let-through energy, which can damage the circuit
  • - Suitable for branch circuit device protection
  • - Thermal-magnetic overcurrent protection
  • - Three levels of short-circuit protection, categorized by B, C and D curves
  • - Trip-free design—breaker can not be defeated by holding the handle in the ON position
  • - Captive screws cannot be lost
  • - SWD (switching duty)—suitable for switching fluorescent lighting loads
    (In ≤ 20A)
  • - Fulfill UL 489, CSA C22.2 No.5 and also IEC 60947-2 Standard
  • - For use in applications for which UL 1077 or CSA C22.2 No.235 are also allowed
  • - Field installable shunt trip and auxiliary switch subsequent mounting
  • - Separate version for ring-tongue connection (Type FAZ-RT), terminal screws can be removed (on both sides)
  • - Module width of only 17.7 mm (per pole)
  • - Contact Position Indicator (red/green)
  • - Easy installation on DIN rail
  • - Possibility for sealing the toggle in ON or OFF position

Tripping Curves to Choose From

Eaton FAZ-NA branch circuit breakers are available with “B,” “C” and “D” tripping characteristics. B-curve devices are suitable for applications where low levels of inrush current are expected.

C-curve devices are suitable for applications where medium levels of inrush current are expected. Applications include small transformers, lighting, pilot devices, control circuits and coils. C-curve devices provide a medium magnetic trip point.

D-curve devices are suitable for applications where high levels of inrush current are expected. The high magnetic trip point prevents nuisance tripping in high inductive applications such as motors, transformers and power supplies.

Eaton FAZ-NA devices are current limiting, which means they interrupt fault currents within one half cycle of the fault. Current limiting devices offer superior protection by reducing peak let-through current and energy.
