All-or-Nothing Relays designed to meet high power switching applications with up to three changeovercontacts, rated 4000 or 7500 VA - AC1.They are ideally suited for arduous duties where safety and reliability are at premium, being capable ofreplacing small contactors switching resistive loads. The 3 mm contact gap version is very popular suiting thestrictest safety standards.Now available in a wider choice of mounting options, ranging from fixing tabs to DIN-rail flange on cover or thetraditional 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.
