Metrel newsletter Metrel help: Fuse tables guide  We have published a comprehensive guide to fuse tables we use, named “Metrel fuse tables guide”. It includes tables with reference values of minimum prospective short-circuit currents and maximum impedances related to a chosen current and disconnection time. The values are strictly related to a chosen fuse or circuit breaker type. These reference values are used in our instruments (in user manuals they are referred to as “Fuse tables guide”) for pass/fail limits when measuring line and loop impedances. An example of a relation between fuse table and »Z line« measurement result. Link to Metrel fuse tables guide Metrel d.o.o.
