Note: Quick connect terminals are not in compliance with IEC standards.
Rated load
DEMKO (EN61058-1)
Note: 1. The inductive load has a power factor of 0.7 minimum (AC).
2. The motor load has an impulse current 6 times the normal current.
3. The above ratings were tested under the following conditions:
(1) Ambient temperature: 20±2 °C
(2) Ambient humidity: 65±5 %RH
(3) Switching frequency: 7 times/min.
