Product details

The Siemens 3RU2136-4JB0-Z W96 is a thermal overload relay for motor protection, rated 54-65 A and built to Class 10 trip characteristics — meaning it will open the circuit within 10 seconds at 7.2× the set current, fast enough to protect standard induction motors during a locked-rotor event without nuisance tripping on normal starts. The manual-automatic-reset selector gives the commissioning engineer a choice: auto-restart for remote/unattended installations, or manual reset so a maintenance tech must physically clear the fault before restart.

RoHS compliance is confirmed from October 2014 onward.

Integration notes

The relay sits on the contactor's Size S2 mounting interface; no additional DIN-rail bracket required if the contactor is already rail-mounted. Pack dimensions (60 × 60 × 50 mm) give a rough idea of the envelope, but the actual installed height depends on the contactor it couples to.

Frequently asked questions

What is the group code and product group for this relay?

The group code is R711 and the product group is 5346. These are internal Siemens classification codes used for catalog organization and cross-referencing.

What compliance documentation is available for this overload relay?

RoHS compliance is confirmed from October 15, 2014. REACH Article 33 disclosure identifies lead (CAS 7439-92-1) above 0.1% w/w. Export control classifications are AL: N and ECCN: N.

What does the Class 10 trip rating mean in practice?

Class 10 means the relay will trip within 10 seconds at 7.2 times the current setting. This is the standard choice for standard squirrel-cage induction motors — fast enough to protect against locked-rotor conditions while allowing normal starting inrush.
