1 Relè di Potenza All-or-Nothing Relays designed to meet high power switching applications with up to three changeover contacts, rated 4000 or 7500 VA - AC1. They are ideally suited for arduous duties where safety and reliability are at premium, being capable of replacing small contactors switching resistive loads. The 3 mm contact gap version is very popular suiting the strictest safety standards. Now available in a wider choice of mounting options, ranging from fixing tabs to DIN-rail flange on cover or the traditional screw-mounting on base, just to suit any kind of modern application. Meeting IEC-CEI-VDE-UL-CSA standards, design includes a dust cover, 0.25" Faston terminals (6.3x0.8 mm) and flame resistant thermosetting terminal-block material.
