C. Overload Protection with KBAP-240D (P/N 9106) (Optional)
The KBAP-240D is a multipurpose DC Current Sensing Relay and Overload Protector. It is specifically designed for
use with DC motors and speed controls from 1/8 - 3 HP. KBAP-240D operates by sensing current in the armature
circuit. When the preset level is reached, the output relay (RY1) trips. An adjustable time delay (0.2 - 15 secs.) is
incorporated, which eliminates nuisance tripping. Manual or automatic reset is provided at the user's option along
with a LED, which indicates when the preset current level has been reached. When an overload occurs, the KBAP-
240D can be used to shut the system down, sound an alarm, or initiate corrective action before damage occurs.
