It operates on a 22 V DC control circuit and is a direct service part for existing TeSys contactor assemblies. The coil has a DC wide-range control circuit type, with an average resistance of 0.72 Ohm inrush and 172 Ohm holding at 20 °C. Control voltage limits are 0.85 to 1.1 Uc for operational range and 0.15 to 0.2 Uc for drop-out, both at 55 °C. The ambient air temperature for operation spans -5 to 55 °C. The 22 V DC control voltage is the nominal coil supply. The operational voltage limits (0.85 to 1.1 Uc, or roughly 18.7 to 24.2 V DC) tell you the coil will reliably pick up across that range at 55 °C. The drop-out range (0.15 to 0.2 Uc, or about 3.3 to 4.4 V DC) means the contactor will drop out cleanly when the control voltage falls that low, preventing the coil from holding in a partially energized state. The operating time of 40 to 50 ms closing and 40 to 65 ms opening is standard for a power contactor coil. The coil has no built-in suppressor module. This means you need to add an external flyback diode or RC snubber across the coil terminals if your control circuit requires suppression, which is typical for PLC-driven outputs or any DC switching circuit where back-EMF could damage the driver.","metaTitle":"TeSys LX4FH022 Contactor Coil, 22 V DC, Obsolete","metaDescription":"TeSys LX4FH022 contactor coil, 22 V DC, obsolete.
