The modular Wengart household AC contactor (36 mm\nhousing width) is a heavy-duty control cabinet switching device according to\nthe international test standard IEC\/EN 61095. Designed for professional use in\nself-sufficient PV isolated systems, modern climate controls, intelligent heat\npump systems (such as SG-ready switches) as well as for complex control\nnetworks in the smart home, this four-pole in-line installation device offers\nuncompromising performance. Thanks to the robust internal mechanism, it is\nvalidated for safe operation in a wide temperature range from -20°C to +60°C\nat an insulation voltage of $U_i$ 500V. The anti-return guide: observe the 2NO\n+ 2NC mixing configuration! By far the most common reason for mispurchases and\nunwanted marketplace returns for modular shooters on mobile devices is the\nmisunderstanding of asymmetric contact assignment. Please check your switching\nmatrix before purchasing: this device has two contact contacts (2NO) and two\nopener contacts (2NC). It is not a standard 4NO contactor for simultaneously\nswitching on 3-phase loads! This means that as long as there is no current at\nthe control coil, the two NC paths are closed and the two NO paths are open.\nAs soon as you apply AC 24 V control voltage, this condition reverses at the\nsame time (change\/lock function). A careless connection of all phases to the\nseparate load paths leads to a fatal short circuit when switching. This short\npre-check protects your system from serious incorrect installations. Important\nnote on acoustics: hum-free permanent hold with clear switching clicks. A\ncommon pain point for control cabinet components are false expectations of\noperating noise in the immediate living area. This Wengart contactor has been\nacoustically optimised twofold: when tightened, the AC solenoid operates\ncompletely silently thanks to integrated short circuit rings and free from\nannoying mains hum (humm-free). However, since the contactor is designed for\ncurrents up to 25A, the inner mechanism has strong contact springs. When\nswitched on and off (11.5 VA switch-on power), the device therefore produces a\nclear, crisp mechanical switching noise. This tactile feedback is ideal for\ncontrol cabinets in technical rooms, garages, cellars or carports - it is not\nrecommended for bedrooms where absolute silence in the switching moment is\nrequired. Precise terminal specifications and important installation practice\ntip The performance terminals hold rigid copper conductors from 1.5 to 6$mm^2$\n(or flexible cables with ferrules from 1 to 4$mm^2$) at a recommended\nstripping length of 9mm. The clamps allow an exact tightening torque of up to\n0.8 N.m using a PZ1 screwdriver, which effectively minimises contact\nresistance. Please refer to the official installation layout according to\nindustry standards for permanent full load operation: if this contactor is\nmounted close to electronic controls (such as timers or thermostats), spacers\n(intermediate pieces in the 9mm pitch) must be inserted on both sides to\nensure optimal cross ventilation and prevent dangerous hotspots in the\nhousing.
