MPN: 1SCA134378R1001
Alt. SKU: OTDC25US2
Why Choose the OTDC25US2 [1SCA134378R1001]
The OTDC25US2 PV disconnect switch is designed for reliable isolation in photovoltaic systems. It features a base mounting configuration and a US single-wire break mechanism. The switch is rated for 25 A at 600 VDC (UL) and 25 A at 660 VDC (IEC), with a reduced rating of 16 A at 1000 VDC (IEC). A terminal bolt kit is included for secure connections; however, the handle and shaft must be ordered separately to complete the assembly. This switch is suitable for single-circuit applications requiring robust and compliant DC disconnection.
