Resettable electronic fuse replacement instrument which plugs into an appropriate socket instead of the fuse. Ideal for short circuits or troubleshooting in the electrical circuit, given that the faulty fuse doesn´t need to be permanently replaced.
The ST 01 fuse tester enables convenient, simple testing of flat fuses (standard / mini) in removed or inserted state.
A green LED on the tester indicates whether the fuse is functional.
The safety jack at the shaft end facilitates removal and replacement of fuses in compact fuse boxes.
Voltage testing device for 12/24 V with test-LED for dependable control of cigarette lighter sockets and standard sockets.
No unwanted short circuit from inattentive use of conventional voltage testers. Can also be used for small sockets such as those with motorcycles via removable compensating sleeve.
Can be used for example as part of an inspection.
