Max. switching characteristics
(DIN EN 60947-4-1/ EN 60947-5-1):
AC 1: 250V/8A
AC 15: 230V/6A
DC 1: 24V/8A
DC 13: 24V/5A/0.1Hz
Maximal contact load at AC 1 with 230V:
2 contacts each with 8A
3 contacts each with 6A
Contact lifetime
1) Max. excitation voltage with contact load < 6A
2) Min. excitation voltage (guaranteed values)
without previous operation
No heat accumulation due to intrinsic heating
of other components.
Continuous duty 100%.
