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.","metaTitle":"Schneider LX4FH155 TeSys contactor coil, 155 V DC","metaDescription":"Active TeSys FH contactor coil, 155 V DC wide range, 32.97 Ω inrush / 7042 Ω holding.
