Outdoor isolation video
This video explains enclosed switch disconnectors for outdoor isolation: switch body, protective enclosure, AC/DC rating, IP rating, lockout function, and buyer checklist items that also apply when selecting an SHP waterproof isolator switch box.
SHP combines the rotary handle, enclosure, gear panel, and isolating switch core in one local disconnect box.
Clear ON/OFF operation for maintenance isolation. Confirm lockable handle and marking needs.
Wall-mount enclosure protects the switch body and wiring space from outdoor exposure.
Match current rating, poles, and terminal arrangement before production. Compare related isolator switch families.
Use this table for enclosure size, handle projection, mounting spacing, and cable clearance before installation drawing approval.
| Model | A | B | H | H1 | D2 | A1 | A2 | A3 |
|---|---|---|---|---|---|---|---|---|
| SHP0-16/20 | 100 | 80 | 65 | 35 | 4.5 | 92 | 60 | 60 |
| SHP1-25/32 | 125 | 100 | 85 | 35 | 4.5 | 115 | 80 | 80 |
| SHP3-40/63 | 175 | 115 | 100 | 35 | 4.5 | 165 | 90 | 90 |
| SHP5-80/100/125 | 240 | 160 | 95 | 35 | 4.5 | – | 193 | 142 |
Use SHP where a visible local disconnect is needed outside the main cabinet. Check cable entry, mounting position, and lock-off needs.
Outdoor pumps, compressors, and auxiliary drives needing a nearby ON/OFF isolator.
Rooftop units and ventilation equipment needing visible service isolation near the load.
Wall-mounted disconnects near machinery when the main cabinet is too far from the load.
Outdoor service points where box size, cable entry, and IP marking must be checked.
Choose SHP when the project needs a box-style enclosure, visible ON/OFF handle, and more routing space. Confirm SHP0/SHP1/SHP3/SHP5 size.
Compare SH30 weatherproof isolators when the switch must stay narrow beside the load.
Compare LW28 waterproof cam switch boxes for selector, transfer, reversing, or multi-step programs.
Use the model code to confirm switch model, current, pole count, box code, and handle style.
Compare the waterproof box guide, SH30 boxes, LW28 boxes, or the main isolator switch range when the route is not fixed.
| Item | Catalogue reference | How to use it |
|---|---|---|
| Model and current | SHP0-16/20, SHP1-25/32, SHP3-40/63, SHP5-80/100/125 | Select by equipment load, upstream protection, cable size, and wiring space. |
| Waterproof box code | L0 / L1 / L3 / L5 | Match the enclosure size in the drawing table and confirm mounting clearance. |
| Poles and handle | 3P / 4P, red-yellow rotary handle, GSC style shown | Confirm pole count, handle color, and lockable handle requirement before quotation. |
| Material and protection | Plastic SHP boxes and separate stainless steel waterproof box assemblies shown | Confirm material, marked IP rating, UV exposure, cleaning environment, and whether stainless steel enclosure review is required. |
| Cable entry | D2 and mounting dimensions shown in the SHP drawing table | Check gland size, cable direction, and wall mounting clearance. |
Final rating depends on switch mechanism, rated voltage, poles, and duty category. Use this as a quotation checklist.

Shieldhz is Zhejiang Shihe Electric’s export brand. Founded in 2014 in Zhejiang, China, the factory supports ISO 9001-managed production and exports to 50+ markets.
SHP is supplied as an enclosed isolator switch assembly, not only an empty box. The normal configuration includes the enclosure, rotary handle, front plate, and internal switch mechanism selected by rating, pole count, and application duty.
The SHP family covers 16A to 125A configurations across SHP0, SHP1, SHP3, and SHP5 box sizes. Confirm the actual load, upstream protection, cable size, and installation space before choosing the enclosure group.
Yes, SHP is intended for outdoor and wet-area local isolation points when the enclosure, cable glands, and installation method are matched correctly. Confirm IP65 marking, cable entry direction, UV exposure, and washdown conditions for each project.
Common configurations include 3P and 4P. The quotation should specify pole count, current rating, handle type, box size, and whether neutral switching or a special terminal arrangement is required.
They are SHP waterproof box size codes used in the catalogue model structure. L0 is used with compact SHP0 builds, while L1, L3, and L5 map to larger SHP enclosure groups with different footprint and wiring space.
Yes. SHP is normally selected for visible local isolation and maintenance disconnect functions. For selector, transfer, reversing, meter selection, or multi-step control logic, use an enclosed LW28 waterproof cam switch box instead.
Yes. Provide cable direction, gland size, wall mounting position, rated current, pole count, quantity, and destination market so Shieldhz can match the enclosure and switch configuration and prepare the correct drawing or datasheet package.
Send current rating, voltage, poles, box size, quantity, market, certificate requirement, and application. Shieldhz will confirm enclosure fit, drawings, MOQ, and lead time.
