Cover for Size S2 — Panel Integration Note
The SIRIUS 3RT1936-4EA2-ZW98 is a terminal cover for box terminals on Size S2 contactors and overload relays. It mounts over the box terminals, providing IP20 finger protection on the front of the contactor or relay. The cover is supplied in multi-unit packaging of 70 units, intended for panel builders or MRO planners who need a batch of covers for a standardized line.
This part carries a current lifecycle stage, but the description explicitly flags it as a phased-out product. The official successor is the SIRIUS 3RT2 series — the terminal cover for that platform is the direct replacement. For a BOM line that still references the 3RT1936-4EA2-ZW98, the sourcing posture is clear: it is not in active factory production, but it remains available through independent distribution channels. If you are qualifying a new panel design, specify the 3RT2-series cover instead to avoid a future last-time-buy scramble.
