Its control circuit voltage range is 220-380 V AC at 50-400 Hz, with a sealed operating time of 25 ms. The 220-380 V AC control voltage range covers both 230 V and 380 V line supplies common in European and Asian panels, but the 50-400 Hz frequency tolerance means it also works on 60 Hz systems without derating. The 25 ms sealed operating time is standard for a contactor coil of this size — fast enough for motor starts, slow enough to avoid nuisance dropouts from voltage sags. The inrush power of 380-520 W (450-620 VA) is high relative to the hold-in power of 0.15-0.2 W. That inrush peak matters for sizing the control transformer — it must supply that surge without dipping below the coil's dropout threshold of 167-189 V. The 77.2 Ω average resistance at 20 °C confirms the coil is wound for AC operation. Mechanical durability of 1,200,000 cycles and a maximum operating rate of 120 cycles per minute at 55 °C means this coil is suited for moderate-duty applications — not continuous high-speed pick-and-place, but fine for typical motor starting on conveyors or pumps.","metaTitle":"WB1KB136 TeSys contactor coil, 220-380V AC, obsolete","metaDescription":"WB1KB136 TeSys contactor coil, 220-380V AC 50-400Hz.
