Application Example
Entire Vehicle Switching and Circuit Protection
Combining a high-amp TH Series Time Delay Relay (TDR) with a 5015 Fuse Block attached to the TDR input stud (left) provides 24 hour / keep-alive circuits; while the second 5015 Fuse Block (right) attaches to the output stud of the TDR providing switched circuits for the installation. The TDR can operate both as a remotely controlled switch and optionally in an autonomous mode after a prescribed time from a trigger event or due to a low input voltage situation. Fuse blocks shown without included covers.
Installation Example
12 Position RT Fuse Block, RT Ground Block, and TH Series Time Delay Relay (TDR)
A well installed power distribution and clean ground return solution. Fused vehicle power is connected to the TDR Time Delay Relay (upper right), then distributed to the 12 Position RT Fuse Block (left). The RT Ground Block (lower right) was separate from the Fuse Block where it was originally tied together, and re-located to a more convenient locations for effective wire harness routing. Also shown, optional cover labels from emergency vehicle label sheet set.
