. 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).)
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.
The time-delay device has combined with undervoltage release with the same voltage the time-delay device.5-1-1. After circuit-breaker closing, the geared motor immediately
sees reloading the closing springs.5-2-3 s
Geared motor for automatic closing spring loading (M)
This automatically loads the circuit-breaker operating mechanism closing springs.2 s
Loading time: 4-a s
Insulation voltage 2500 (for min.
When not supplied, circuit-breaker closing prevented.
