Product details

Siemens 3RU6116-1EB0 is a SIRIUS thermal overload relay sized S00, adjustable 2.8...4 A, Trip Class 10, for motor protection. Mounts directly onto a contactor — no DIN rail needed. Current production.

The adjustable current range 2.8...4 A sets the motor FLA this relay protects. Set the dial to match the motor nameplate full-load amps; Size S00 is the smallest SIRIUS contactor frame; the relay clips onto the contactor's front face. That saves DIN-rail space in a panel — the assembly occupies the contactor footprint plus 70 mm depth forward. Ambient operating range -40 to +70 °C covers most industrial enclosures, including those near hot processes.

Mounts on Siemens contactors of size S00 (e.g. 3RT201 series). Screw terminals accept 2x (0.5...1.5 mm²) solid/stranded or 2x (0.75...2.5 mm²) for the main circuit; auxiliary terminals take 2x (20...16) AWG. Tightening torque 0.8...1.2 N·m. Any mounting position allowed. Requires 6 mm side spacing to grounded parts.
