The control circuit is 155 V AC at 40...400 Hz, so this is the voltage you need to supply from the panel to pull in the contactor. Coil technology is listed as without built-in suppressor module — meaning you'll need to add an external RC snubber or varistor across the coil if the control circuit drives inductive loads or long cable runs. The 8 W heat dissipation at rated voltage is steady-state; factor that into enclosure thermal rise. Operating time is 100...170 ms opening and 40...65 ms closing. That's the mechanical stroke time — it tells you the contactor won't drop out faster than 100 ms, which matters for ride-through on voltage sags. The dropout threshold is 0.35...0.55 Uc (about 54 to 85 V AC), so the coil holds in down to roughly half the nominal voltage; below that it releases. Maximum operating rate is 2400 cycles per hour at 55 °C. That's one cycle every 1.5 seconds — fine for normal motor starting or resistive load switching, but not for high-speed jogging or frequent inching duty. Ambient operating temperature is -5 to 55 °C. Inside a closed panel near other heat sources, the top end gets tight — derate the operating rate or add ventilation if the panel ambient exceeds 40 °C.","metaTitle":"TeSys LX1FH1552 Contactor Coil, 155 V AC 40-400 Hz","metaDescription":"TeSys LX1FH1552 replacement contactor coil for LX1F contactors. 155 V AC 40-400 Hz control circuit, 8 W dissipation, active production.

The closest alternative would be another LX1F coil with a different control voltage — for example, a 110 V AC or 220 V AC variant — but those are not pin-compatible unless the control circuit voltage matches. No direct drop-in substitute with the same 155 V AC rating exists in the same series."},{"question":"What is the LX1FH1552's listed range and category?","answer":"The range is TeSys, and the category is 22341-CONTACTOR,D,K,&F ACCESS — meaning it is an accessory coil for the TeSys D, K, and F contactor families."},{"question":"What compliance documentation does Schneider Electric provide for the LX1FH1552?","answer":"The evidence does not list specific compliance documents (RoHS, REACH, UL, IEC) for this order code.
