Contactors for domestic reactive and resistive load switching up to 25A
25 October 2010
Finder has introduced a family of 25A contactors for switching lighting, pump and motor loads in noise sensitive installations. Featuring an ac dc silent coil with varistor protection, the 22 Series modular two and four pole contactors come in compact 17.5mm and 35mm wide housings, and include a standard 35mm rail mounting for simple consumer unit installation. The contactors' minimum 3mm double break normally open (NO) contact gap and protective separation between coil and contacts ensures installation safety standards are met.
The contact material options are AgNi and AgSnO2, the first intended for resistive and slightly inductive loads as well as motor loads, the latter for lamp loads and high inrush current loads. The contact configurations for the two pole products are 2NO, 1NO+1NC and 2NC and for the 4-pole products, 4NO, 3NO+1NC and 2NO+2NC. The auxiliary contact block is provided in 1NO+1NC and 2NO versions. Finder 22 Series 25A modular contactors are designed and tested in accordance with EN 61095: 2009, electromechanical contactors for household and similar purposes.
