The SIRIUS 3RT1936-4EA4 is a terminal cover for box terminals, designed for Size S2 4-pole contactors and overload relays in the SIRIUS family. It covers the box terminals on the load side, providing IP20 touch protection at the terminal area when installed.
Lifecycle and replacement
This part is a phased-out product. The preferred successor order code is 3RT2936-4EA4, also a SIRIUS terminal cover for the same Size S2 box-terminal contactor and overload relay family. If you are sourcing for a BOM line that specifies 3RT1936-4EA4, the 3RT2936-4EA4 is the official drop-in replacement — same form factor, same fit, same function.
Compliance note
The 3RT1936-4EA4 carries a substance prohibitance date of 07/01/2006, indicating it meets RoHS restrictions effective from that date. As a standard SIRIUS accessory, it is covered by the same IEC and UL certifications as the contactor family it serves.
