DIN Rail Mounting Relays
2-pole relay FA2DE20 (Large-Capacity Type)
▼Features
The glass-enclosed contacts are unaffected by the external atmosphere, solving the contact failure problem of in-air contact type relays.
Long mechanical life with few driving parts ensures long life even in high frequency switching applications.
Since glow discharge is performed at the time of inductive load disconnection, surge voltage is low and the product is friendly to the electronic components of peripheral equipment.
The mechanical contact provides complete insulation, preventing equipment malfunctions caused by leakage current from semiconductor relays.

Glossary of Terms
Term | Definition |
Rated Continuous Current | Rated continuous current is the current value which can be energized continuously without exceeding the allowable temperature rise under the condition without breaking contacts. |
Rated Operational Current | Rated operational current is the current value which is combined with a rated operational voltage and used in regulated conditions (making/breaking current, switching frequency and electric switching durability). At 220VAC, the current is set at 10 times this value upon making (PF: 0.6 to 0.7) and 1 times this value upon breaking (PF: 0.3 to 0.4). Rated operational current 0.5A means 5A making and 0.5A breaking. At 110VDC and 220VDC, the current is set at 1 times making and 1times breaking and indicated by inductive load (L/R=100ms). |
Maximum Making Current | Maximum making current is the current value which enables 10 times making referring to IEC 62246-1. |
Maximum Breaking Current | Maximum making current is the current value which enables 10 times breaking referring to IEC 62246-1. At 110 VDC and 220 VDC, maximum making current is the current value which enables 10 times breaking by inductive load (L/R=100ms). |
Operating Time | Conditions：Ta=20℃ cold start, rated coil voltage is applied. Bounce Time not Included |
Releasing Time | Conditions：Ta=20℃ cold start, rated coil voltage is applied and turn off from rated voltage applied state. |
Vibration/Shock resistance | Values of vibration/shock resistance are obtained when Bestact is equipped with a vibration proof band. |
Maximum allowable voltage | Maximum allowable voltage is the maximum value that can be applied to the coil in consideration of its thermal degradation and insulators in the relays.This is not a continuous allowable voltage. |
