MCT Rectangular Sealing Modules · S1 / S2 / S3
One module family, one cable-range logic, sized to fit the rectangular cut-out you already have.
S1, S2, and S3 modules share the same channel geometry and cable-range steps across three depths — 60 mm, 40 mm, and 30 mm — so a shallower or deeper frame does not force a redesign. Cable diameters from 3 mm to 99 mm are covered across the size range.
Before you order
Check your frame's channel pitch and available depth against the cross-reference table below. Module depth (L) must match or fit inside the frame cavity.
Specification table
S1 series — center plug, L = 60 mm
Full depth modules for standard rectangular frame cavities. Each model covers a fixed cable-range window; select by the diameter you need to seal.
| Model | Channels | Cable range | External size | Weight |
|---|---|---|---|---|
| M15S1 | 1 | 3–11 mm | 15 × 15 mm | 0.02 kg |
| M20S1 | 1 | 4–14.5 mm | 20 × 20 mm | 0.04 kg |
| M30S1 | 1 | 10–25 mm | 30 × 30 mm | 0.08 kg |
| M40S1 | 1 | 21–32 mm | 40 × 40 mm | 0.14 kg |
| M60S1 | 1 | 28–54 mm | 60 × 60 mm | 0.32 kg |
| M60V2S1 | 2 | 24–54 mm | 60 × 60 mm | 0.64 kg |
| M80S1 | 1 | 48–71 mm | 80 × 80 mm | 0.6 kg |
| M120S1 | 1 | 67.5–99 mm | 120 × 120 mm | 1.2 kg |
Material: EPDM + silicone rubber diaphragm.
Shallower-depth variants
S2 (L = 40 mm) and S3 (L = 30 mm)
Same cable-range logic as S1, in shorter and lighter bodies, for frames where cavity depth is limited. Cable range across the S2/S3 line covers 3–32 mm.
| Series | Depth (L) | Size reference | Cable range | Notes |
|---|---|---|---|---|
| S2 | 40 mm | M15S2 – M40S2 | 3–32 mm | Mirrors S1 sizes M15–M40 at reduced depth |
| S3 | 30 mm | M15S3 – M40S3 | 3–32 mm | Shortest body, for space-constrained cavities |
Full size range for S2 and S3 mirrors S1's smaller models (M15–M40). Request the complete list with your enquiry.
Cross-reference table
Existing module → DEWIN equivalent
Describe your current module by its dimensions. This table maps common rectangular module sizes to the closest DEWIN model and the cut-out check to confirm before ordering.
| Your current module | DEWIN equivalent | Frame cut-out | Fit check |
|---|---|---|---|
| 15 × 15 mm, 1 channel | M15S1 | 120-frame single-channel | Drop-in, no rework |
| 20 × 20 mm, 1 channel | M20S1 | 120-frame single-channel | Drop-in, no rework |
| 30 × 30 mm, 1 channel | M30S1 | 120-frame single-channel | Drop-in, no rework |
| 60 × 60 mm, 2 channels | M60V2S1 | 120-frame dual-channel | Confirm channel pitch |
| 80 × 80 mm, 1 channel | M80S1 | 120-frame single-channel | Confirm cavity depth ≥ 60 mm |
| 120 × 120 mm, 1 channel | M120S1 | 120-frame single large channel | Confirm cavity depth ≥ 60 mm |
Applications
Where these modules are specified.
Energy storage
BESS containers
Rectangular entries between battery racks and control compartments, matched to existing 120-frame cut-outs without modifying the container wall.
Sizing guide →Data centre
Modular hall penetrations
Dense rectangular penetrations through prefabricated wall panels, re-openable when cable runs are added later.
Sizing guide →Switchgear
Control panel entries
Standard rectangular cut-outs, so an existing enclosure design needs no rework to qualify a second source.
