Product details

The Siemens SIRIUS 3RU2916-3BJ20 is a touch protection cover for the outgoing side of a 3RU21 overload relay in Size S00, designed for ring cable lug connections. It clips onto the relay to provide shock protection on the main circuit terminals, keeping live parts covered after wiring. At 9 mm deep, 45 mm wide, and 18 mm tall, it adds minimal projection to the relay assembly — useful when panel space behind the DIN rail is tight or when the relay sits near a gland plate.

Clip-on fastening means no tools or additional hardware are needed for installation — it snaps directly onto the 3RU21 relay body.

Frequently asked questions

What are the key dimensions of this terminal cover?

The cover measures 9 mm deep, 45 mm wide, and 18 mm tall, adding minimal depth to the overload relay assembly.

Does this cover fit the 3RT1016-2AP02 contactor?

No. The 3RU2916-3BJ20 is designed specifically for the outgoing side of a 3RU21 overload relay in Size S00, not for the 3RT1016-2AP02 contactor. The contactor uses a different terminal cover designed for its spring-loaded terminal block.

What compliance documentation is available for this part?

As a standard Siemens SIRIUS component, it carries the usual CE marking for the European market and is manufactured under Siemens' ISO-certified quality system. Specific RoHS or REACH declarations would be available through Siemens' documentation portal using the order code.
