.Time delay device for undervoltage release (D)
The undervoltage release can combined with electronic time-delay device for installing outside the circuit-breaker, which enables delay
in the tripping the release with preset, adjustable times.
When there power supply during maintenance work, the closing springs can still loaded manually (by means the special lever on
the operating mechanism).
Power supply 24-30 AC/DC
4S-60 AC/DC
100-130 AC/DC
220-2a0 AC/DC
Operating limits: 85.
The characteristics the time-delay device are:
Power supply (D): 24-30 AC/DC
48 AC/DC
60 AC/DC
110-127 AC/DC
____________________________________ 220-250 AC/DC
Adjustable opening time (YU D): 0.5-2-3 s
Geared motor for automatic closing spring loading (M)
This automatically loads the circuit-breaker operating mechanism closing springs. „110% (CEI 6094y-Standards)
Inrush power consumption (Ps): 500 W
AC 500 VA
Rated power (Pn): 200 W
AC 200 VA
Inrush time 0.
The time-delay device has combined with undervoltage release with the same voltage the time-delay device.5-1-1.
