Weatherproof SH30 enclosed isolator switch for pumps, HVAC equipment, outdoor machinery, and local service disconnects from 20A to 125A.
Choose H1, H3, or H5 by current group, cable entry, mounting space, and duty category. Confirm the drawing and document package before quotation.
The SH30 weatherproof format combines the load isolator, enclosure, rotary handle, and cable-entry layout in one compact local disconnect inside the wider isolator switches range.
Wall-mount enclosure protects the switch body and keeps the operator, wiring route, and maintenance point easy to identify.
Red/yellow front handle gives clear ON/OFF operation; confirm padlock, label language, and market certificate needs during quotation.
Send current, poles, cable gland direction, quantity, market, and required files before quotation to avoid enclosure or drawing mismatch.
Use the table to compare box depth, cable-entry position, and mounting holes by SH30 model group before layout, drilling, or gland selection.
| Model | D3 | D4 | H | B | K | A1 | A2 | Mounting |
|---|---|---|---|---|---|---|---|---|
| SH30-20/25/32 | 23 | 19 | 82 | 85 | 160 | 150 | – | D2 4.2 |
| SH30-40/63 | 29 | 23 | 93 | 100 | 190 | 178 | – | D2 4.2 |
| SH30-80/100/125 | 37.5 | 23 | 107 | 145 | 250 | – | 229 | B 124 / D2 6.5 |
Use the table for SH30 current groups, 240V/440V references, AC duty rows, cable-entry notes, and mounting checks.
Compare with the waterproof isolator box guide, SHP waterproof isolator boxes, and SH30 load isolator switches; reference IEC 60947-3.

Shieldhz is the export brand of Zhejiang Shihe Electric Co., Ltd., founded in 2014 in Zhejiang Province, China.
Factory background includes ISO 9001 management, 5,000+ m2 production space, 100+ employees, 40+ machines, and supply across 50+ markets.
Use SH30 for outdoor equipment, service points, and wall-mounted local disconnects. For solar PV or battery-side DC circuits, compare the DC isolator switch range.
Outdoor pump skids and motor service points needing a visible disconnect near the equipment. Confirm current rating, cable entry, and mounting dimensions.
Rooftop and wall-mounted HVAC units that need compact local isolation. Share fan or compressor load details and rated voltage.
Packaging machines, conveyors, and small outdoor equipment where operators need clear switching status. Confirm lock-off practice and label language.
Wet-area panels, farm equipment, service cabinets, and building utility points where the switch sits outside the main control cabinet.
Choose SH30 when the disconnect must sit beside pumps, HVAC units, or outdoor machines with a slim footprint.
Compare SHP waterproof isolator boxes when cable bending room or box volume is the priority.
Compare LW28 waterproof cam switch boxes for selector, transfer, reversing, or step-control operation.
SH30 uses a narrower enclosed switch format for compact local isolation, while SHP uses larger box-style enclosures across SHP0, SHP1, SHP3, and SHP5 sizes. Choose SH30 when the installation needs a slim weatherproof isolator beside equipment. Choose SHP when the project needs broader box-size routing, more enclosure space, or a different product family layout.
No. This page is for SH30 installed in a weatherproof enclosure with surface mounting and cable-entry planning. The open SH30 isolator switch is the switching body family; the weatherproof SH30 box combines that isolating function with a protective enclosure, operator handle, and drawing-controlled installation dimensions.
Yes. Confirm current rating, rated operational voltage, pole count, handle function, enclosure size, cable gland direction, quantity, and target market before quotation. Shieldhz will then check whether the selected 20A, 25A, 32A, 40A, 63A, 80A, 100A, or 125A catalogue group fits the duty and installation space.
Use IEC 60947-3 for the isolating switch function, then verify the exact certificate, report, and market requirement against the selected model. For procurement, do not rely on the standard name alone; ask for the datasheet, dimension drawing, wiring diagram, and available certificate copy before production approval.
They are SH30 waterproof box size codes in the catalogue. H1 is used for compact builds, H3 for mid-size builds, and H5 for larger weatherproof isolator boxes. The box code should be checked together with current group, D3/D4 cable entry, and mounting spacing before installation drawings are released.
The catalogue groups SH30 waterproof box dimensions around SH30-20/25/32, SH30-40/63, and SH30-80/100/125 models. These groups help buyers shortlist the enclosure size, but the final quote should still confirm utilization category, A/kW values, rated voltage, pole arrangement, and document package for the target market.
Yes, when the selected rating, enclosure, cable entry, and installation method match the project requirements. For HVAC, pump, and machinery service points, send the load type, voltage, cable size, location, quantity, and lock-off requirement so Shieldhz can match the correct SH30 box group and approval files.
Send current rating, rated voltage, pole count, box code, cable entry, quantity, market, and certificate needs. Shieldhz will confirm fit, drawings, MOQ, and lead time.
