< Load current indicator LED >
The current value, which is used as a reference by the load
current indicator LED, varies depending on the applications
and relay types.

Note) When the "OVER" LED of WS, WB, or WF type or the "100%" LED of
WM type is lit, the current value is over the uninterrupted current. The
breaker will trip after the ETR set time is passed.
< Control power supply >
This is required for the trip cause indicator (LED, contact output), the measurement extension module, displays, etc. Over-cur-
rent and short-circuit protection is performed by the power supply CT energy, even if the control power supply is not available.

(1) Overcurrent protection is powered by the CT, which is built into the breaker. It
is operable regardless of the external power supply.
Ground fault protection (GFR) is also operable at 0.2 to 1.0 rated current (In)
settings, regardless of the control power supply.
(2) 6 contact outputs are set as below.

With the power supply types P3 and P4, high-sensitivity relays are used for contact outputs. Because of that, contact outputs may
trigger chattering noise (approx. 1 ms of mis-outputs) at breaker opening/closing in some panel installation conditions. When us-
ing the product in a fast-response sequence, install a filtering circuit of a few milliseconds or perform double reading of samples.

CAUTION
< Pre-alarm operation >
PAL LED will blink when the current exceeds the pre-alarm
current setting (Ip), and will be lit after 1/2 of the long time
lag (T ) is passed. The power supply type P3 to P5 will also

perform a contact output. For the operation time period, re-
