Phoenix Contact MSTB 2,5/15-STF-5,08

Contact plating (finish) provides corrosion protection for base metals and optimizes the mechanical and electrical properties of the contact interfaces.

Current rating is the maximum current that a fuse will carry for an indefinite period without too much deterioration of the fuse element.

In general, the absolute maximum common-mode voltage is VEE-0.3V and VCC+0.3V, but for products without a protection element at the VCC side, voltages up to the absolute maximum rated supply voltage (i.e. VEE+36V) can be supplied, regardless of supply voltage.
