It is a service part — the coil itself, not a complete contactor — intended for field replacement when the original coil fails or a different control voltage is needed. Rated for 150 V AC at 50 Hz control circuits, it draws 75 VA inrush at 0.55 power factor and settles to 8 VA sealed at 0.28 power factor. The average DC resistance measures 207.57 Ohm at 20 °C, within a ±10 % tolerance. Inductance is 6.6 H. The 150 V AC 50 Hz rating is the control voltage the coil is wound for — apply that across the terminals and the magnetic circuit pulls in the contactor armature. The inrush figure (75 VA) is what the control transformer or PLC output must deliver momentarily; the sealed figure (8 VA) is the holding power after the contactor closes. A control transformer sized for the inrush peak avoids voltage sag that could prevent full pick-up. The 207.57 Ohm resistance at 20 °C is the coil winding's DC value, useful for verifying the coil with an ohmmeter before installation — a short or open winding reads well outside the ±10 % band. The 6.6 H inductance matters for suppression circuit design: a standard RC snubber across the coil contacts should be selected for this inductance to avoid excessive voltage spikes on dropout.","metaTitle":"TeSys LX1LB150 replacement coil, 150 V AC 50 Hz","metaDescription":"Active TeSys LX1 coil for 150 V AC 50 Hz control circuits. 207.57 Ohm resistance, 75 VA inrush / 8 VA sealed.
