What It Is and Where It Goes
The Siemens 3RU5956-3AA01 is an adapter bracket accessory for the 3RU S6 overload relay family — the mounting interface that lets you fit the relay onto the contactor or into the panel layout cleanly.
What the Ratings Mean for Fit
Touch protection on the front is rated finger-safe for vertical contact from the front per IEC 60529 — meaning an operator reaching into the panel cannot accidentally contact live metal behind the bracket. That matters when the panel door is open for troubleshooting and the overload relay is energized. Protection class IP20 on the front means the bracket itself is protected against solid objects larger than 12.5 mm (fingers) but not against water ingress — standard for inside a closed enclosure where condensation isn't a concern.
Sourcing and Lifecycle Reality
With a lifecycle stage of current, this bracket is not subject to phase-out or last-time-buy constraints. It is sourced and quoted to order against an RFQ through independent distribution; availability and current pricing are confirmed at quote time.
