| Description | PTC Fuse; 4.00 A; 60 V |
| Datasheet | Download Datasheet |
The OptiFuse RS60SB-400 is a 4 A hold radial-lead resettable PTC fuse, rated 60 V maximum.
A PTC fuse carries its hold current indefinitely; on an overcurrent it heats, its resistance rises sharply and it limits the current to a trickle, then resets on its own once the fault is removed and power is cycled. This one always trips at 8 A, in max. 24.0 s at 20.00 A.
It withstands a fault current of up to 40 A at rated voltage. Resistance: minimum 0.014 Ω, 0.060 Ω maximum one hour after tripping. Tripped, it dissipates typically 3.70 W. It operates from -40 to +85 °C.
Construction: outline 21.00 W x 24.90 H x 3.00 T mm (max.); lead spacing 10.2 mm; leads 20 AWG (0.81 mm); tin plated copper.
