Albright equivalent SW400R-100 400A 12V DC or 24V DC Miller Welder 224697 SW400A/12V Welding Contactor
The SW400R-100 has been designed for Direct Current loads, including motors as used on electric vehicles such as industrial trucks. Developed for both interrupted and uninterrupted loads, the SW400 is suitable for switching Resistive, Capacitive and Inductive loads.
The SW400R-100 features Single pole Single throw, Double breaking main contacts with silver alloy tips, which are weld resistant, hard wearing and have excellent conductivity. The SW400 has M10 stud main terminals and 6.3mm spade coil connections. It can be mounted via M5 tapped holes or mounting brackets – either supplied fitted, or as separate items. Mounting can be horizontal or vertical, when vertical the M10 contact studs should point upwards. If the requirement is for downwards orientation we can adjust the contactor to compensate for this.
