Product Description
ASW400-2T 12V/24V/36V/48V/60V/72V/84V/120VDC 400A 2NO+2NC DPDT Electrical Equipment Parts Battery Car DC Relay AOKAI DC Contactor
The ASW400-2T contactors has been designed for direct current loads, particularly motors as used on electric vehicles such as industrial trucks, airport tractors, etc.
They have double breaking main contacts with silver alloy contact tips, which are weld resistant, hard wearing and have excellent conductivity.
The ASW400-2T main contact circuit, designed for motor reversing, is such that it has a built-in failsafe, so that if both coils are energized simultaneously the contact arrangement is open circuits.
Installation: Mounting is via the supplied mounting bracket.
Magnetic Blowouts: Fitting of magnetic blowouts make the polarity sensitive and the positive markings on the top cover of the contactor must be observed. Suffix 'B' denotes the fitting of magnetic blowouts.
Auxiliary Contact: Denoted by 'A', a double circuit normally open, normally closed microswitch auxiliary contact can be fitted, ratings as shown below.
