PV DC isolation switch for household and commercial solar systems, covering IP66 waterproof box assemblies, MC4 connector options, and IP20 DIN rail switch bodies across 300V to 1500V DC rating rows.
GF51 covers two installation forms: IP66 waterproof box assemblies for field PV isolation and IP20 DIN rail switch bodies for cabinet installation.
Specify GF51 by voltage row, current series, contact configuration, installation form, and cable entry. Because IP66 and IP20 versions share the GF51 name, the selected code should be checked before quotation.
GF51–16 / 25 / 32/2P / 4P / 4T / 4B / 4S / 2H/IP66 / IP20/M20 / M25 / MC4
GF51-16, GF51-25, and GF51-32 are the DIN rail current families; the IP66 box data also lists 10A, 16A, 20A, 25A, and 32A.
2P and 4P follow the standard rating rows. 4T, 4B, and 4S are series input/output options; 2H is the parallel-pole configuration.
Choose IP66 enclosed form for field mounting or IP20 DIN rail form for cabinet mounting. Specify vertical or horizontal installation.
M20, M25, MC4, or terminal wiring should match the cable gland, connector, enclosure, and cabinet layout.
For 1500V DC ratings, keep the customization note visible until Shieldhz verifies the final drawing and certificate package.
These catalogue values separate the IP66 waterproof-box assembly from the IP20 DIN rail body so ratings are checked against the correct installation form.
Catalogue note: DC 1500V voltage requires customization. Attach the final voltage row, connection diagram, and certificate market to the RFQ. For standards context, compare the project requirement with UL industrial control equipment standards guidance and the final Shieldhz certificate package.
Match the product image to the model code. GF51 should not be quoted from a photo alone because waterproof-box, connector, and DIN rail versions use different accessories and documents.
Field-mounted waterproof box for PV string isolation, with M20, M25, or MC4 cable-entry selection.
Use the open view to check terminal access, gasket path, cover position, and cable entry before drawing release.
Cabinet-mounted option for GF51-16, GF51-25, and GF51-32 switch bodies with vertical or horizontal installation.
GF51 drawings support rating selection, contact configuration, terminal layout, and cabinet clearance checks. Open the wiring and dimension drawings in modal view when the project needs engineering review before quotation.
Example 4P wiring configuration and rating reference from the catalogue graphic. Use it to verify the selected contact code before quotation.
Dimension drawing for cabinet layout, front clearance, handle projection, terminal position, and mounting checks.
Drawing note: match the opened drawing to the selected GF51 configuration before release. The approval package should confirm contact configuration, voltage row, IP rating, terminal layout, cable entry, and document requirements.
Reference wiring and rating graphic for GF51 contact-code review. Verify the final wiring drawing before ordering.
Reference drawing for cabinet layout, handle projection, depth, terminal, and mounting-hole checks.
Do not quote GF51 from a product picture alone. Specify current, voltage, contact configuration, installation form, cable entry, and document requirements before order release.
Choose IP66 waterproof box or IP20 DIN rail switch body before comparing ratings.
Use 300V, 600V, 800V, or 1500V DC from the PV array and derating requirement.
Use 10A-32A for IP66 box assemblies, or GF51-16 / GF51-25 / GF51-32 for DIN rail bodies.
Select 2P, 4P, 4T, 4B, 4S, or 2H from the switch configuration diagram.
Request drawing, label data, certificate copy, IP rating, cable entry, and inspection requirement.
For fast review, send DC voltage, current, contact configuration, IP66 or IP20 installation form, cable entry, target market, quantity, and any customization requirement. If the selection is unclear, compare GF40 enclosed string isolation and GF41 higher pole-count selection first.
GF51 is used as a PV DC isolation switch between photovoltaic modules, combiner boxes, DC cabinets, and inverter inputs. It separates IP66 enclosed field isolation from IP20 DIN rail cabinet mounting, so buyers can match the switch form to outdoor or cabinet installation.
The GF51 tables list 300V, 600V, 800V, and 1500V DC rating rows. For 2P and 4P configurations, GF51-16 is 16A, 16A, 12A, and 8A; GF51-25 is 25A, 25A, 15A, and 8A; GF51-32 is 32A, 32A, 17A, and 8A. The IP66 waterproof box assembly also lists 10A, 16A, 20A, 25A, and 32A.
The IP66 version is a waterproof PV DC isolator box with M20, M25, or MC4 cable entry and a -25 deg C to +85 deg C working range. The IP20 version is a DIN rail switch body for cabinet installation, with vertical or horizontal mounting and storage temperature data from -40 deg C to +85 deg C.
The configuration table lists 2P, 4P, 4T, 4B, 4S, and 2H. The 4T, 4B, and 4S options are series input/output configurations, while 2H is the parallel-pole configuration shown for higher current rows at 300V and 600V.
The dimension drawing shows approximately 60.8 mm top width, 59.8 mm bottom width, 97 mm body height, 86 mm overall depth, 64 mm and 53.5 mm side references, 45 mm handle projection, and a 6.4 mm mounting-hole reference.
Send the DC voltage row, current series, contact configuration, IP66 or IP20 installation form, M20/M25/MC4 or terminal connection, wiring direction, approval market, quantity, and whether a 1500V rating requires customization.
For direct email, contact [email protected] or [email protected].
Share voltage row, current series, contact configuration, IP66 or IP20 installation form, connection type, wiring direction, target approval market, and quantity. Shieldhz will check the GF51 model code, drawing, certificate file, MOQ, lead time, and document package before quotation.
