RELAY LT4706M7S TELEMECANIQUE ,TeSys LT47 electronic over current relays - manual - 0.5...6 A - 200...240 V AC, LT4706M7S

Deskripsi
Relai arus lebih elektronik TeSys LR47, 6A/690V, dengan pengaturan ulang manual, yang akan disuplai dengan arus AC 200-240V, untuk perlindungan motor dengan arus terukur 0,5-5A. Relai ini menyediakan 3 tombol putar untuk menyesuaikan perlindungan, LOAD (0,5-6A) untuk level arus lebih, O-TIME (0,3-10 detik) untuk durasi arus lebih yang dapat diterima, D-TIME (0,5-30 detik) untuk durasi awal. Selain itu, perangkat akan trip ketika ada fase yang hilang selama lebih dari O-TIME. Perangkat ini memiliki tombol reset, tombol uji/henti, 2 indikator LED (Run/Trip), 2 kontak bantu 1NO+1NC untuk pensinyalan kesalahan. Pengaturan dapat dikunci dengan menyegel penutup transparan. Pemasangan rel DIN, tanpa terminal daya (arus dipantau oleh 2 transformator arus yang dilintasi oleh kabel motor). Bersertifikat multi standar (IEC, UL, CSA, CCC, EAC), sesuai dengan peraturan RoHS/REACh
