Geared motor for automatic closing spring loading (M)
This automatically loads the circuit-breaker operating mechanism closing springs.
Power supply 24-30 AC/DC
4S-60 AC/DC
100-130 AC/DC
220-2a0 AC/DC
Operating limits: 85.2 s
Loading time: 4-a s
Insulation voltage 2500 (for min.
When not supplied, circuit-breaker closing prevented.5-1-1.)
It always supplied with limit contacts and microswitch for signalling closing springs loaded.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. „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. The use the delayed undervoltage release recommended when the power supply
network the release can subject power cuts short-lived voltage drops, order avoid trips.
When there power supply during maintenance work, the closing springs can still loaded manually (by means the special lever on
the operating mechanism).

. After circuit-breaker closing, the geared motor immediately
sees reloading the closing springs.
The characteristics the time-delay device are:
Power supply (D): 24-30 AC/DC
