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.<\/p><\/details><details class=\"shz-sh30w-faq-item\" name=\"shz-sh30w-faq\"><summary><h3>Is this the same as the open SH30 isolator?<\/h3><\/summary><p>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.<\/p><\/details><details class=\"shz-sh30w-faq-item\" name=\"shz-sh30w-faq\"><summary><h3>Can the rating be customized?<\/h3><\/summary><p>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.<\/p><\/details><details class=\"shz-sh30w-faq-item\" name=\"shz-sh30w-faq\"><summary><h3>What standard should be referenced?<\/h3><\/summary><p>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.<\/p><\/details><details class=\"shz-sh30w-faq-item\" name=\"shz-sh30w-faq\"><summary><h3>What do H1, H3, and H5 mean?<\/h3><\/summary><p>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.<\/p><\/details><details class=\"shz-sh30w-faq-item\" name=\"shz-sh30w-faq\"><summary><h3>Which SH30 current groups are shown in the catalogue?<\/h3><\/summary><p>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.<\/p><\/details><details class=\"shz-sh30w-faq-item\" name=\"shz-sh30w-faq\"><summary><h3>Can SH30 be used for outdoor HVAC and pump equipment?<\/h3><\/summary><p>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.<\/p><\/details>\n<\/div><\/div><\/section>\n<\/div><\/div><\/div>\n<\/div><\/div>\n\n\n\n<div class=\"wp-block-stackable-columns alignfull stk-block-columns stk-block stk-sh30wcta\" data-block-id=\"sh30wcta\"><div class=\"stk-row stk-inner-blocks stk-block-content stk-content-align stk-sh30wcta-column alignfull\">\n<div class=\"wp-block-stackable-column stk-block-column stk-column stk-block stk-sh30wctac\" data-v=\"4\" data-block-id=\"sh30wctac\"><div class=\"stk-column-wrapper stk-block-column__content stk-container stk-sh30wctac-container stk--no-background stk--no-padding\"><div class=\"stk-block-content stk-inner-blocks stk-sh30wctac-inner-blocks\">\n<!-- SHZ-SH30W-SEC8: CTA -->\n<section id=\"sh30-weatherproof-inquiry\" class=\"shz-sh30w shz-sh30w-sec shz-sh30w-cta\">\n  <style>\n    .shz-sh30w-cta{position:relative;overflow:hidden;width:100%;max-width:100vw;background:linear-gradient(115deg,#061A36 0%,#082B58 56%,#0E4A93 100%);color:#fff;padding:0}.shz-sh30w-cta .shz-sh30w-wrap{position:relative;z-index:1;width:min(1440px,calc(100vw -
