Inrush power consumption (Ps):
DC = 200 W
AC = 200 VA
Continuous power (Pc):
DC = 5 W
AC = 5 VA
Opening time (YU):
30 ms
Insulation voltage
2500V 50 Hz (for 1 min.)
Geared motor for automatic closing spring charging (M)
This carries out automatic closing spring charging of the power circuit breaker operating mechanism. After power circuit breaker closing, the geared
motor immediately sees to recharging the closing springs.
When there is no power supply voltage or during maintenance work, the closing springs can, in any case, be charged manually (by means
of the special lever of the operating mechanism).
Power supply (D):
24-30 V AC/DC
48 V AC/DC
60 V AC/DC
110-127 V AC/DC
220-250 V AC/DC
Adjustable opening time (YU+D):
0.5-1-1.5-2-3 s
Power circuit breaker opening takes place with power supply voltage
values of the trip unit equivalent to 30 - 60% A.
Power circuit breaker closing is possible with power supply voltage of
the trip unit equivalent to 85-110% A.
It can be fitted with a signaling contact for undervoltage release
energized (C. aux YU).
Reference figures in the electrical circuit diagrams: YU 6
Time delay device for undervoltage release (D)
The undervoltage release can be combined with an electronic time-
delay device to be mounted outside in relation to the power circuit
breaker, which allows a delay in intervention of the trip unit with
established and adjustable times. The use of the delayed undervoltage
release is recommended when the power supply network of the trip unit
can be subject to interruptions or short time drops in voltage, in order
to avoid trips.
When it is not supplied, power circuit breaker closing is prevented.
The time-delay device is to be combined with an undervoltage release
with the same voltage as the time-delay device.
Power supply
24-30 V AC/DC
48-60 V AC/DC
100-130 V AC/DC
220-250 V AC/DC
Operating limits:
85…110% Un
It is always supplied with limit contacts and microswitch for signaling closing springs charged.
Reference figures in the electrical circuit diagrams: M
Inrush power consumption(Ps):DC = 500 W
AC = 500 VA
Nominal power (Pn):
DC = 200 W
AC = 200 VA
Inrush time
0.2 s
Charging time:
4-5 s
Insulation voltage
2500V 50 Hz (for 1 min.)
The characteristics of the time-delay device are:
Reference figures in the electrical circuit diagrams: YU + D 7
Tightening torque: 2 Nm
