Pin definition: 1/2 pin coil, 3/4 pin normally open load contact (Form A)
Electrical derating curve: As the load current increases, the relay’s electrical switching life decreases linearly; 16A represents the short-time current limit.
Coil temperature-rise curve: The standard 450mW coil exhibits a higher temperature rise than the 200mW high-sensitivity coil; under high-temperature operating conditions, the low-power, high-sensitivity variant is preferred.
