The Siemens 3RU2116-1EC0-Z X95 is a thermal overload relay sized for motor protection in the 2.8 to 4.0 A range. The relay offers manual-automatic reset, so you can set it to either latch after a trip (manual) or auto-reset once the bimetal cools (automatic). For unattended or remote installations, automatic reset avoids a site visit; for safety-critical guarding, manual reset forces a positive action before restart.
Integration notes
Size S00 is Siemens' smallest contactor/overload frame. The 75 × 47 × 66 mm package fits tight panel layouts; spring-type terminals on the auxiliary circuit accept 0.2–2.5 mm² wire. The manual-automatic reset selector sits on the front face, accessible with the panel door closed.
