Soliswitch FTE20 Technical data
Endress+Hauser 23
Switching capacity
• According to EN 61058: 250 V AC 5E4, 6(2) A
• According to UL 1054: 125 to 250 V AC, 5 A
• 24 V DC, 3 A
• Min. switching load 300 mW (5 V/5 mA)
After a current >100 mA is actuated, it is no longer possible to guarantee the switching
function with a switching current I <100 mA.
