SunTree Fuse Holder SRD-50H 1500VDC 1P

The Suntree CH-50H / SRD-50H is a single-pole DC fuse holder and isolating switch designed for dependable circuit protection and isolation in DC applications such as photovoltaic and energy-storage systems. It is rated for a DC service voltage of 1500 V and an insulation voltage of 1600 V, with available rated service currents from 2 A to 50 A across the listed ratings. The product conforms to IEC/EN 60947-1 and IEC/EN 60947-3 and is classified under utilization category PV-0.

The CH-50H / SRD-50H offers a rated limiting short-circuit current of 50 kA and a rated acceptable power dissipation of ≤12 W. It accepts 10 × 85 mm and 14 × 85 mm fuses and provides IP20 ingress protection. With a 1P configuration and an impulse withstand rating of 8 kV, it supports reliable isolation and fuse protection in compact DC circuits.

As a Suntree fuse holder, the CH-50H / SRD-50H is suitable for DC distribution and protection where 1500 V DC capability, single-pole isolation, and compatibility with standard 10 × 85 mm or 14 × 85 mm fuses are required. Its specified short-circuit performance and PV-0 classification make it a practical choice for photovoltaic and energy-storage applications.
