Overview
VIOX CJX2s contactor accessories support auxiliary signalling,
time-delay control, interlocking, coil transient suppression and motor
overload protection. Select each accessory by its function and the exact
contactor frame; the items shown are individually selected components,
not a bundled kit.

Interlocks and Dust Covers
| Accessory | Catalogue compatibility |
|---|---|
| KMI mechanical interlock | CJX2s-09–38 |
| KMI electrical interlock | CJX2s-09–95 |
| KDC-1 front dust cover | CJX2s-09–38 |
| KDC-2 front dust cover | CJX2s-40–95 |
Select interlocks for the actual paired-contactor arrangement. A
front dust cover does not establish a new enclosure IP rating.
Coil Surge Suppression
Modules
| Module | Contactor frame |
|---|---|
| FS-M | CJX2s-M06–M16 |
| FS-18 | CJX2s-09–18 |
| FS-32 | CJX2s-25–32 |
| FS-65 | CJX2s-40–65 |
| FS-95 | CJX2s-80–95 |
The catalogue lists AC/DC voltage bands of 24–48 V, 100–250 V and
380–440 V. Select the module voltage version to match the coil supply as
well as the contactor frame. These coil suppression accessories are not
distribution-panel surge protective devices.
Thermal Overload Relays
| Relay | Available adjustment ranges (A) | Listed contactor frames |
|---|---|---|
| JR28s-25 | 0.1–0.16; 0.16–0.25; 0.25–0.4; 0.4–0.63; 0.63–1; 1–1.6; 1.25–2; 1.6–2.5; 2.5–4; 4–6; 5.5–8; 7–10; 9–13; 12–18; 17–25 |

Each adjustment range is a separate selection. Choose a relay range
that includes the motor nameplate current and coordinate it with the
contactor and short-circuit protective device.
Ordering Information
