DC PV Isolating Switch

The DC PV Isolating Switch is specially designed for solar photovoltaic systems, with a rated current of 32A and suitable for DC 1000V/1200V systems. Adopting a 2‑pole structure, it provides safe disconnection, obvious physical isolation, and reliable protection during circuit maintenance.

The switch features an IP66 waterproof and dustproof enclosure, ensuring stable performance in outdoor environments such as rooftop and ground‑mounted solar power stations. It is equipped with a lockable operating handle to prevent misoperation and improve safety during installation and maintenance. The internal arc‑suppression design effectively suppresses DC arcs during switching, extending electrical life and enhancing operational reliability.

Equipped with standard MC4 connectors, this PV isolator enables tool‑free quick wiring and is compatible with most solar panels and inverters. It complies with IEC 60947‑3 and PV DC switch standards, featuring long mechanical life and stable contact performance.

Suitable for residential, commercial and industrial PV systems, the GYZL32/2 DC isolating switch provides safe circuit isolation during maintenance, troubleshooting and emergency shutdown, making it an essential componntial compeliable and safe operation of solar power systems.

Strong Point

• IP66 protected, durable outdoors
• Lockable handle, safe operation
• DC arc extinguishing, stable breaking
• MC4 connector, easy installation

Usage environment:

The DC PV Isolating Switch is suitable for various indoor and outdoor photovoltaic DC power distribution scenarios and can operate stably at altitudes up to 2000 meters. It features an operating temperature range of -40℃ to +85℃, adapting to outdoor conditions with high or low temperatures and large temperature differences between day and night.

It is ideal for installations free from strong vibration, corrosive gases, and flammable or explosive media. Widely applied in rooftop PV systems, ground-mounted power stations, PV combiner boxes, and inverter DC circuits, it meets safety isolation and maintenance requirements for residential, commercial, and industrial photovoltaic systems.

• In a photovoltaic DC system, a DC PV Isolating Switch creates a clear and visible electrical disconnection point, providing reliable safety protection for equipment maintenance and line overhaul, effectively preventing electric shock and accidental switching risks.
• Its dedicated DC arc-extinguishing design quickly suppresses arcs, solving the difficult breaking problem in DC circuits and protecting core devices such as solar panels and inverters.
• The high-protection enclosure adapts to complex outdoor environments, resisting high and low temperatures, water and dust, ensuring long-term stable system operation.
• In addition, the lockable handle meets safety standards to prevent misoperation by non-professionals, making it an essential component for PV power stations to achieve safe operation, extend equipment life, and improve overall system safety.

1.Disconnect the power supply of the PV system before installation, confirm no voltage in the circuit, and install the switch in a dry place free from strong vibration and corrosive gas.

2.Fix the switch base on the wall or bracket with supplied screws. Ensure stable installation and keep a proper drainage angle for the IP66 structure to avoid water accumulation.

3.Strictly distinguish positive and negative poles. Connect the PV panel side to the input terminal and the inverter side to the output terminal with MC4 connectors. Reverse connection is prohibited.

4.Check that all connectors are fully plugged and tightened. Close the switch enclosure after confirming correct wiring to maintain good sealing.

5.Rotate the handle clockwise to the ON position for circuit connection, and counterclockwise to the OFF position for safe isolation.

6.Set the handle to OFF during equipment maintenance and lock it through the lock hole to prevent accidental closing.

7.Frequent switching on and off with load is prohibited to avoid contact damage caused by DC arc. Always verify no voltage before maintenance.
