ASW-A720 600A M12 ON-OFF Battery Switch

DAIERTEK ASW-A720 is a rotary battery disconnect switch specified for 600 A working current and 2,500 A cranking current at 12 V DC, with a 12-48 V DC operating range. The body measures 102 x 102 x 90 mm, with 2 x M12 terminal studs and ON-OFF operation. The two-terminal arrangement connects a single battery feed to its outgoing circuit; OFF isolates that circuit. Surface or recessed mounting supports vehicle auxiliary-power installations. Current ratings are reduced by 50% at 24 V DC. The product is supplied for automotive aftermarket distributors and vehicle equipment assembly programs.
