Developed for professional use in control\nconstruction, industrial automation technology as well as in complex heating,\nventilation and air conditioning (HVAC), this contactor offers uncompromising\nperformance. Thanks to the separation of the power circuit and low voltage\ncontrols, you can realise highly secure machine architectures on the standard\nDIN rail. The anti-return guide: check voltage AC 24 V. A massive pain point\nand the main reason for defectively returned industrial shooter is the\nmisunderstanding regarding the required coil voltage. Please check the current\ntype of your control before wiring: the solenoid of this contactor requires an\nAC voltage of AC 24 V (50\/60 Hz) on the terminals A1\/A2. The device does not\nhave a DC coil and must not be connected to a standard DC 24V power supply (DC\nswitching power supply). Applying DC current leads to instant overcurrent coil\nfiring and destroys the internal mechanics. This short check protects your\ninvestment and prevents unplanned downtime. Integrated 1NC auxiliary contact\nfor uncompromising safety locks. Anyone who has ever tried to set up a\nreversible protection circuit (e.g. for lifting and lowering loads or gate\ndrives) knows the risk of a phase short circuit if both contactors attract at\nthe same time. The Wengart model solves this problem in a space-saving way: a\nmechanically coupled auxiliary contact is already integrated as an opener (1NC\n- Normally Closed) in the housing. Through this auxiliary contact you grind\nthe control voltage of the enemy contactor - attracts contactor A, the NC\ncontact physically interrupts the coil feed line of contactor B. A fatal\nmalfunction is therefore absolutely ruled out without the need to lock\nexpensive external additional blocks. Limits for hard typing operation (AC-3\nvs. AC-4 standard). A common misunderstanding in the trade concerns the load\ncapacity at dynamic engine loads. The contactor lists its performance\nparameters transparently according to official industry standards to provide\nyou with maximum planning security: Operating class AC-3 (normal engine\nstart): full load up to 12 amps permitted. Perfect for compressors, fans or\nstandard motors that start gently and then run through permanently constant\n(up to 5.5 kW power at 380V\/400V). Operating class AC-4 (tap mode \u0026amp; reverse):\ndowngrading to a maximum of 5 amps is required. Applies to applications where\nthe main contacts must separate currents when the engine is locked (e.g. exact\npositioning of cranes or inching operation). Compliance with this reduction\nnoticeably extends the life of your contacts. Technical data at a glance:\nModel: Industrial air contact\/modular design for DIN rail mounting. Standard\nconformity: certified according to international standard IEC\/EN 60947-4-1.\nMain contacts: 3-pole (3NO - NO - NO for three-phase network up to 660V\/690V).\nIntegrated auxiliary contact: 1 NC (opener auxiliary contact for locking\nchains) Coil control voltage (Uc): AC 24 volts AC (50\/60 Hz). Rated operating\ncurrent (Ie): 12 A (class AC-3) \/ 5 A (class AC-4). Standard motor power in\nAC-3 operation: 5.5 kW at 380 V\/400 V \/ 7.5 kW at 500 V. Conventional\ncontinuous thermal current (Ith): solid 20 amps Life metric: 10 million cycles\nmechanical \/ 1 million cycles electric (AC-3).
