It pulls 550 VA inrush at cos φ 0.3 and settles to 45 VA holding — the 12 to 16 W heat dissipation figure tells you the thermal load the panel must shed. Closing time runs 23 to 35 ms, opening 5 to 15 ms. No built-in suppressor module, so you add your own RC snubber or varistor across the coil if the PLC output or relay driving it needs protection. The 154 V AC coil is specific — not the common 110 V or 220 V tap. Drop-out happens between 0.35 and 0.55 Uc (about 54 to 85 V), pick-up between 0.85 and 1.1 Uc (131 to 169 V). If your control transformer delivers nominal 154 V, this coil holds in reliably; if your line sags below 131 V under load, it drops out.","metaTitle":"Schneider Electric LX1FF154 TeSys F Contactor Coil, 154 V AC","metaDescription":"Obsolete TeSys F contactor coil, 154 V AC 50 Hz, 550 VA inrush, 45 VA hold-in, 12-16 W dissipation.
