It's a replacement coil for the LX1D8 series, meant to drop into the existing contactor assembly without re-engineering the panel. Key specs: inrush power of 300 VA at 60 Hz (cos φ 0.8), hold-in consumption of 22 VA (cos φ 0.3), and a coil resistance of 243.07 Ω at 20 °C. The control voltage limits are 0.85...1.1 Uc for pickup and 0.3...0.6 Uc for dropout at 55 °C.
The 380 V AC 60 Hz control voltage is specific — this coil will not work on 50 Hz or DC control circuits without modification. The absence of a built-in suppressor module means you need to add an external RC snubber or varistor across the coil if driving it from a PLC output or solid-state relay, otherwise the inductive kickback can damage the control electronics. Heat dissipation of 3 to 8 W at 60 Hz means the coil generates noticeable heat inside an enclosed panel. If the contactor is in a tightly packed cabinet with other heat sources, verify the ambient stays within the -5 to 60 °C operating range to avoid premature coil failure.
