Note: Care shall be taken on the heat generated on PC board when maximum carrying current exceeds 10A. Please perform the confirmation test with actual conditions. * : Minimum switching loads mentioned above are reference values. Please perform the confirmation test with actual load before production since reference values may vary according to switching frequencies, environmental conditions and expected reliability levels. * Electrical life at resistive load mentioned above are the values when a varistor is used as coil suppresion device. Using protection device other than varistor, the contact life expectancy may decrease drastically. 2
