*1. The values given above are initial values.
2. Once a load has been switched by the contact, do not use it with a load of lower capacity connected. The contact surface may become rough, which could compromise contact reliability.
*1. This protective structure is based on test methods according to the standard (EN60947-5-1). Please confirm the sealing performance in advance under actual operating environment and usage conditions.
*2. The durability conditions are based on an ambient temperature of 5 to 35°C and an ambient humidity of 40 to 70% RH.
*3. Do not apply 1 A/125 V AC to more than two circuits.
*4. This value may vary depending on switching frequency, environmental conditions, and reliability level. Please check with the actual load in advance.
*5. Measurement Condition: 5 to 8 V DC, 0.1 A, depending on the voltage descent method.
