GE Industrial Solutions Time Delay Module - Manual

Introduction
Time Delay Module:
The de-energizing operation of the undervoltage
release can be delayed. This optional, externally
mounted, module has an adjustable time delay of
one to three seconds. The device can be
implemented to prevent un-desired Breaker
‘tripping’ due to momentary voltage outages
(50% of rated Voltage) and is connected in series
with the under voltage release. The delay is in
addition to the Under Voltage Release delay of 50
msec. The breaker must have a UVR installed for
the External Time Delay Module to work.

WARNING: Before installing any accessories, turn the
breaker OFF, disconnect it from all voltage sources,
and discharge the closing spings.
AVERTISSEMENT: Avant d’installer tout accessoire,
mettre le disjoncteur en position OFF, le déconnecter
de toute tension d’alimentation , et décharger les
resorts d’armement
Refer to DEH-41410 for the Under Voltage
Release in the breaker
Use the following procedure to install the Time
Delay Module (TDM) accessory into the circuit
breaker.
1. Verify that the rating on the Time Delay Module
(TDM) identification plate matches the voltage
rating required for the application, as listed in
Table 1.
2. The time delay module has to be mounted
external to the breaker.
3. Switch off the breaker & equipment and ensure
the panel is isolated
4. TDM module can be mounted in two ways
either using two M4 screws on the panel or to a
din rail.
5. For assembling using the screw, drill and tap
two M4 holes at a distance as shown in the Fig. 1.
