* Note: Atfrequencyof 60Hzclosing timeisreduced by 1.2times.
Dutycycle (accordingtoEN 60 034-1,8):
EASP 1-Ex aredesigned for remotecontrol:
short-timeoperation S2-10 min
intermittedoperation S4-25%,max. 90 cycles per hour
EASP 1-Exwithcontroller aredesigned for automotiveregulation:
intermittedoperation S4-25%, 90up to1200cycles perhour
Note:
1. Dutycycle consist of load type, load factorand switching rate.
