CSO Series Heavy-Duty Clips

CSO Series Heavy-Duty Clips

Schurter is expanding its range to include a fuse clip designed for heavy-duty performance. The CSO fuse clip for 10.3 x 38 mm or 10.3 x 85 mm fuses is suitable for applications with voltages up to 1500 VAC/VDC and currents to 32 A. The fuse clip’s unique characteristics meet or exceed the present need for increasing photovoltaic system voltages.

The CSO clip is available in solder and screw/rivet versions. The solder-type allows direct mounting on a printed circuit board by means of through-hole technology. The screw/rivet version provides additional flexibility for basic designs. Due to the special copper alloy both versions are characterized by a strong-clamping force resulting in minimal power loss.

The CSO fuse clip is ideal for a wide-range of PV and other DC applications including inverters, battery charge controllers, and string fuseholders. It is equally-well-suited for use in the energy and industrial electronics industries. The fuse clip conforms to RoHS specifications and is currently the only photovoltaic clip on the market with cURus approval. Schurter also offers the ASO gPV, 1000 VDC UL approved, 10.3 x 38 mm fuse to fit the new CSO fuse clip. The fuse clip also supports fuses with a 10.3 mm diameter of any length including a 10.3 x 85 mm for higher-voltages.
