Notes:
1) All parameters, unless otherwise specified, are measured at an ambient temperature of 23°C.
2) PCB Mounting Holes - the “*” hole is not needed for the SPST-NO version.
3) At an ambient temperature of 85°C, the maximum allowable coil voltage should be reduced to 72%.
4) Electrical life obtained at resistive or inductive load at 30A/15VDC with suitable arc suppression attached and with an operating frequency of 1 op/sec.
