Star-delta timing from 0.5 s to 120 s
The H3CR-G8L AC100-120 sits in Omron's H3CR-G series of plug-in timing relays and runs as a star-delta controller with a settable delay from 0.5 Sec to 120 Sec, hand-dial adjusted on the front face, which is the parameter that decides whether it fits a motor transition window on the starter cubicle. Timing initiates on input voltage rather than a separate trigger terminal, so the start command and the timing run are wired to the same supply feed in the typical star-delta starter layout.
Output contact and coil supply
The output is a single SPST-NO (1 Form A) mechanical relay rated 5 A at 250 VAC — that figure sets the ceiling for the contactor coil it can drive directly, and any starter coil above 5 A at 250 VAC needs an interposing relay between the timer and the contactor. Coil supply is 100–120 VAC on an 8-pin octal plug-in base, which is the standard footprint on retrofit starter panels: an existing 11-pin timer drops out and the H3CR-G8L seats into the same octal socket pattern.
Field swap and sourcing
Omron lists the part as active in a mature lifecycle phase, so production is ongoing and the swap path is a like-for-like octal-base replacement on the existing socket — no panel rework, no rewiring beyond what the wiring diagram already shows. For panel builders and MRO spares, the unit is specified into the BOM and quoted per RFQ against the required quantity; current availability and lead time are confirmed at quote time.
