Product details

The LX4FH155 is a TeSys FH contactor coil rated at 155 V DC, with an operational window of 0.85...1.1 Uc at 55 °C and a drop-out threshold of 0.15...0.2 Uc.

Coil resistance is 32.97 Ω at 20 °C during pull-in, then 7042 Ω holding. Closing time is 40...50 ms; opening time is 40...65 ms.

Integration note — suppressor module

This coil ships without a built-in suppressor module. Plan for an external free-wheeling diode or varistor across the coil terminals.

This is a service part (Category 18401-WORLD SERVICE PARTS) for TeSys F contactors.

Frequently asked questions

What TeSys range does this coil belong to?

It's part of the TeSys range, specifically the FH series of contactor coils.

What is the control voltage and type?

155 V DC, wide range — operational from 0.85 to 1.1 Uc at 55 °C, drop-out between 0.15 and 0.2 Uc.

Does this coil include a built-in suppressor?

No — it ships without a built-in suppressor module. An external suppression device is recommended for DC applications.

What are the coil resistance values?

Inrush resistance is 32.97 Ω at 20 °C; holding resistance is 7042 Ω at 20 °C.
