1.2 System overview
Figure 1: Contactor monitoring devices
The CMD contactor monitoring device requires a control power supply.
CMD(24VDC), CMDTD: control voltage 24 V DC
The CMD relay can be combined with the following Eaton contactors,
motor-protective circuit-breakers and circuit-breakers:
• Contactors/contact modules, fitted with an auxiliary NC contact as
mirror contact and an additional auxiliary NO contact
Control voltage 24 V DC:
• DILM(C,S)7, DILM(C,S)9, DILM(C,S)12, DILM(C,S)17, DILM(C,S)25,
DILM(C,S)32, DILM(C,S)40, DILM(C,S)50, DILM(C,S)65,
DILM(C,S)80, DILM(C,S)95, DILM(C,S)115, DILM(C,S)150
• DILEEM-G, DILEM-G
• DILM185A, DILM225A
• Motor-protective circuit-breakers, circuit-breakers and
switch-disconnectors, fitted with an undervoltage release:
• NZM1, N1 + NZM1-XU (HIV20)(L)18DC
• NZM2, N2 + NZM2/3-XU (HIV20)18DC
• NZM3, N3 + NZM2/3-XU (HIV20)18DC
1.3 Improper use
The CMD contactor monitoring device has only been tested and approved in
combination with the Eaton contactors and circuit-breakers that are listed in
￫ section 1.2, “System overview”, page 25.
￫
The contactor must be provided with an auxiliary NC contact
that is designed as a mirror contact in accordance with
IEC/EN 60947-4-1 Annex F.
The auxiliary NO contact and auxiliary NC contact must be
interlocked opposing in accordance with IEC/EN 60947-5-1
Annex L.
The contactor and the CMD are fed with the same control
voltage.
￫
The CMD must therefore only be combined with these devices.
