Impulse Output for a Trip Coil
The low-energy trip coil of the circuit breaker is connected to terminals TC+ and TC− of
the terminal block X4. The trip energy is provided by a capacitor store integrated in the
protection relay. See also ╚═▷ “4.1.1.1 Trip Pulse and WIC1 LEDs”.
Length of each trip
impulse:
(approx.) 50 ms
The pause between the individual pulses depends on the
impedance of the tripping coil and the current level. Pulsing
is continued until the protection function’s tripping state
drops o󰊞.
Trip energy: E ≥ 0.1 Ws
Voltage: 24 VDC nominal voltage
Relay Output (WIC1‑4)
With the device variant WIC1‑4, it is possible via setting parameter [Device Para / WIC1 /
Output] »Prot . Out. Mode« to select between two operating modes for the output “Out+/−”:
• = “Impulse Output” — The contacts “Out+/−” function as an impulse output for a•
󰊠ag indicator. This operating mode is fully compatible to the “FI+/−” impulse output
of the 󰊟rst generation WIC1, see also ╚═▷ “Impulse Output for a Flag Indicator (all
WIC1 variants)”.
• = “Syst. O.K. & Ext.Suppl.” — The contacts “Out+/−” output a digital signal, so•
that an external output relay (of a particular type, see ╚═▷ “9.1.8.3 Relay Ouput
(WIC1‑4)”) can be connected.
The main application for this output relay is its use as a self-supervision contact. For
details, see ╚═▷ “3.7.1 Self-Supervision Contact for the WIC1‑4”.
Remark: The “Syst. O.K. & Ext.Suppl.” operating mode is also available with the “no-output-
variants” WIC1‑4xxxN. However, for the device variants WIC1‑1, WIC1‑2, WIC1‑3 the
operating mode “Impulse Output” is 󰊟xed, so that the output can only be used for triggering
a 󰊠ag indicator.
Impulse Output for a Flag Indicator (all WIC1 variants)
Depending on the order option, the WIC1 can feature an impulse output for a 󰊠ag indicator.
A 󰊠ag indicator can be connected to terminals FI+/− (WIC1‑4: Out+/−) of the terminal block
X4, e. g. for a power-safe signaling of a trip. See also ╚═▷ “3.7.3 Impulse Signal for the
Flag Indicator”.
Length of each trip
impulse:
(approx.) 50 ms
The pause between the individual pulses depends on the
impedance of the 󰊠ag indicator and the current level.
Pulsing is continued until the protection function’s tripping
state drops o󰊞.
Energy: ≥ 0.01 Ws
