The DC92 has been designed for direct current loads, particularly motors as used on small
electric vehicles such as light industrial trucks. Developed for both interrupted and
uninterrupted loads, the DC92 is suitable for switching Resistive, Capacitive and Inductive
loads.

Uninterrupted current - no or infrequent load switching
requirements (maintains a lower contact resistance).

The DC92 features double breaking main contacts with silver
alloy tips, which are weld resistant, hard wearing and have excellent
conductivity. The DC92 is a monoblock construction, resulting in a
neat compact design which is compatible with modern electronic
control systems. The M8 stud main terminals can be configured
in a variety of ways in order to suit the application. Supplied with
a mounting bracket as standard, or alternatively supplied with M4
tapped holes. Mounting can be horizontal or vertical, when vertical
the M8 contact studs should point upwards. If the requirement is for
downwards orientation we can adjust the contactor to compensate
for this.

Interrupted current - opening and closing on load with frequent
switching (results in increased contact resistance).
