Monitoring relay 71.31.8.400.1010
Manufacturer: Finder (Italy)
Monitoring relay 71.31.8.4000.1010 detects and trips on out-of-limits L-N voltage, and protects against excessive “starts/hour” through ”power-on” and “lock-out” time delays.
Typical applications - protection of compressor motors and high pressure discharge lamp circuitry.
— Three phase 400VAC.
— Rated current 10A.
— Adjustable symmetrical over/under voltage limits (±5...±20)% Un.
— 1 change-over contact (SPDT).
— Link selectable - 5 min or 10 min delay.
