Littelfuse SE-704-0D is a versatile protective relay with a broad frequency range (50; 60; ASD) and optional conformal coating. It offers multiple relay contact configurations (1 Form A (N.O.); 1 Form B (N.C.)) and can operate in fail-safe or non-fail-safe mode. With IEEE device numbers 50G - 50N - 51G - 51N, it provides front-panel or remote N.O. contact reset options. The relay also features standard harmonic filtering (DFT), a GF trip time range of 0.03 - 2 seconds, and is suitable for solidly grounded AC or resistance grounded AC systems. It operates on a supply voltage of 12 - 24 V dc, provides latching or autoreset functionality, and offers analog outputs with current range of 0 - 1 mA and voltage range of 0 - 5 V. Convenient front-panel test button and standard CT loop monitoring make installation and maintenance hassle-free.
