Any
1) Electrical equipment for furnaces.
VDE certificate for 3TK28 41 and 3TK28 42 is available.
2) For relay outputs, use a fuse link:
LV HRC Type 3NA, DIAZED Type 5SB, NEOZED Type 5SE:
6 A (weld-free protection at I_K = 1 kA).
3) For instantaneous output.
4) When the cascading input is supplied from A1, the maximum response
time is applicable to an external EMERGENCY-STOP.
5) The drivers are not supplied, internal supply bridging only.
SELV/PELV power supply unit buffered.
