Form factor and what lands in the panel
The H3Y-4-B AC100-120 5S is listed as a TMR 4PDT unit with a 5-second timing range and a black housing, packaged in bulk. The order-code suffix carries the AC100-120 coil band directly — drop it into a control panel wired for that mains voltage without an interposing transformer.
Series identity and where it sits
The series is recorded simply as "*" in the spec line, with the descriptive entry resolving it as a TMR 4PDT 5-second black-body timer. In an Omron bill of materials this maps onto the H3Y family — a compact, panel-mounted timing relay used for sequence-interlock and reset-delay duty rather than the higher-density H3DK or H3CR DIN-rail timer lines.
