The supply range of 100–120 VAC lets the unit ride directly on a 120 V control transformer secondary common in North American MCC buckets, and the timing window of 0.5 sec to 120 sec covers the typical star-to-delta changeover band where starting transients must settle before full-line connection. ## Output contact, socket, and wiring fit The output is a single SPST-NO (1 Form A) mechanical contact rated 5 A at 250 VAC — adequate to drive the coil of the line contactor that completes the delta connection, but the 5 A ceiling means the unit belongs in the control circuit, not in the power path of the motor itself. Termination is an 8-pin octal plug-in, and the unit is socketable so a failed timer pulls straight out of its base without disturbing the rest of the starter wiring — the practical advantage on a hot starter swap where downtime is the dominant cost. ## Timing adjust and initiation Timing initiate is keyed to input voltage, so the star interval starts the moment the coil sees line potential — no separate trigger terminal to wire. The delay is set with a hand dial on the front face, which is the field-friendly choice when commissioning techs need to trim the star interval against a real load without a programming tool.","metaTitle":"Omron H3CR-G8EL AC100-120 Star Delta Timer, 100-120VAC","metaDescription":"Omron H3CR-G8EL AC100-120 H3CR-G series star-delta timer, 0.5–120 sec, 5 A SPST-NO mechanical relay, octal plug-in.
