Notes:
1: All parameters, unless otherwise specified, are measured at ambient temperature of 23ºC.
2: Maximum make current refers to inrush current of motor load.
3: Electrical life is strongly dependent of switching frequency, On/Off ratio and environmental conditions.
Specifications are subject to change without notice. E&OE.
