Product details

No built-in suppressor — plan for it

This coil ships without a built-in suppressor module. On an AC coil driving an inductive load, the back-EMF spike at drop-out can couple noise into adjacent 24 VDC control wiring — it's noise till proven otherwise. Fit an external RC snubber or MOV across the coil terminals, or use the TeSys LA4 series suppressor module. The 8 W heat dissipation at rated voltage means the coil runs warm; ensure ventilation around the contactor in a densely packed panel.

Operating time and thermal limits

Opening time spans 100 to 170 ms; closing time is 40 to 65 ms. That's on the slower side for a contactor coil — fine for motor starting or resistive load switching, but not for fast cyclic applications. Maximum operating rate is 2400 cycles per hour at 55 °C, which works out to one operation every 1.5 seconds.

No official successor exists because none is needed; the LX1FH0322 remains the standard replacement coil for the LX1F contactor frame at 32 V AC.

Frequently asked questions

What is the control voltage and frequency range?

Rated 32 V AC, 40 to 400 Hz. Drop-out occurs at 0.35 to 0.55 Uc (11 to 17.6 V); pick-up requires 0.85 to 1.1 Uc (27 to 35 V).

Does this coil include a built-in surge suppressor?

No. The coil technology is listed as 'without built-in suppressor module.' An external RC snubber or MOV must be added across the coil terminals to suppress back-EMF when de-energizing.

What is the heat dissipation of this coil?

8 W at rated voltage across the 40 to 400 Hz range. Account for this heat in your panel thermal calculation, especially in a densely populated enclosure.
