DS1-32 PV Switch Disconnector | DC Isolator 1000V 32A (IP20)
(1) Indoor DC isolator for solar PV systems, 1000V/32A, IP20 cabinet installation.
(2) Compact cabinet-mounted PV switch disconnector for inverter isolation.
(3) 2P/4P options, lockable handle, compliant with IEC/EN 60947-3.
The DS1-32 is an indoor DC isolator designed for cabinet installation in solar photovoltaic systems, rated 1000V/32A. Compact and reliable, it ensures safe disconnection between solar panels and inverters during inspection, servicing, or emergencies.
This cabinet-mounted PV switch disconnector is ideal for switchboards, inverter rooms, and distribution panels where environmental protection is already provided by the enclosure. The device complies with IEC/EN 60947-3, supporting utilization categories DC-PV1 / DC-PV2, with a service life of up to 15,000 mechanical operations.
The DS1-32 is available in 2-pole and 4-pole versions, giving flexibility for different wiring configurations. The lockable rotary handle prevents unauthorized use, improving operator safety.
Typical applications
Inverter input isolation inside PV cabinets
Residential and commercial distribution boxes
DC string isolation in protected indoor environments
System integration
The DS1-32 can be paired with DC fuse holders and DC surge protective devices to complete a safe and reliable PV protection solution.
