After circuit-breaker closing, the geared motor immediately
sees reloading the closing springs.lta (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).)
It always supplied with limit contacts and microswitch for signalling closing springs loaded.
