ASW-A701N 300A ON-OFF Battery Disconnect Switch

DAIERTEK ASW-A701N is a rotary battery disconnect switch with ON-OFF operation and two 3/8-inch terminal studs. It is specified for 300 A working current and 1,250 A cranking current at 12 V DC, over a 12-48 V DC operating range. Current ratings are reduced by 50% at 24 V DC. Its 68 x 68 x 75 mm body defines the installation footprint. The two-terminal layout connects one battery feed to its outgoing load circuit, while OFF isolates that circuit. The product is supplied for automotive aftermarket distributors and vehicle auxiliary-power assembly programs.
