In modern\nelectrical installations, flexibility is key to longevity. The Wengart WCT-25M\nis not just an ordinary contactor, it is your tool for precise energy\nmanagement. With its 1NO + 1NC (1 N\/O contact, 1 opener) configuration and\nrobust hand control lever, it allows direct physical control of your circuits.\nThe advantage of manual overcontrol: Why is a manual switch important? When\ntroubleshooting or starting up a new heat pump or lighting controller, you\noften want to manually test the circuit without waiting for a signal from the\nPLC or smart home actuator. With the WCT-25M you simply switch to position \"I\"\nand bridge the automatic mechanically - safe and reliable. FAQ - Important\ntips for installation in Germany: Q: What does \"1NO + 1NC\" mean in practice?\nA: This means that one circuit closes (NO) when the contactor tightens, while\nthe other opens at the same time (NC). This is ideal for priority switching\n(load shedding) to prevent two large consumers from overloading the network at\nthe same time. Q: Is the shooter suitable for use in the hallway? A: Yes,\nthanks to our silent technology, there is no annoying magnetic humming. It is\nalmost silent in operation, making it ideal for sub-distribution near living\nspaces. Q: Will the lever stay securely in the selected position? A: Yes, the\nmechanism is designed to lock the lever securely in the positions \"I\"\n(continuous on) and \"O\" (continuous off) until it is manually reset to \"Auto\".\nQ: What cable cross sections can be connected? A: The solid cage clamps are\ndesigned for common cross sections up to 6 mm² (rigid) or 4 mm² (flexible with\nferrule), which is completely compliant for the fuse with 25A.\u003c\/p\u003e \n\n\u003ch3\u003eProduct Features\u003c\/h3\u003e\n  \u003cul class=\"a\"\u003e\n         \u003cli\u003eThree position manual switch (I-Auto-O): Full control in any situation. The integrated lever allows three modes: continuous ON (manual), automatic (via control signal) and continuous OFF.
