Technical Data
Relay 736
Description
Polarized latching relay for 100 A.
The relays are designed and manufactured in accord-
ance to the Standards of IEC 61810, Part 1-00/VDE 0435,
Part 201, which are also in accordance to the Low
Voltage Directive (LVD).
The advantage of the polarized latching relays is the pulse
driven operation of 30 miliseconds. Therefore there is
a low need of setting power and the coil heating can be
neglected.
The relays are designed and manufactured in accordance
to international standards of IEC 61810 part 1/VDE 0435
part 201 as well as they meet overload and short circuit
requirements of IEC 62053/62054/62055(UC3).

Relay 736
2/3
The power terminals can be modified according to customer
specification.
A shunt is integrated into one of the power terminals of the
type 736 CR. It is used to
measure the energy consumed and, as it is integrated in the
relay, can be utilised for
load shedding in Energy Management. Two connectors are located
on the terminal
close to the shunt and only carry the current sensor signal. A
third connector is the
reference signal for the electronics and is located on the
supply side of the terminal to
avoid RF sensitivity.
