Product Description

The Siemens 3RU6116-1GB0 is a compact thermal overload relay from the SIRIUS 3RU6 series, providing reliable inverse-time delayed protection for motors with normal starting characteristics. With adjustable current setting from 4.5 to 6.3 A and Class 10 tripping, it is ideal for small to medium motors up to ~2.2–3 kW @ 400 V. Features manual/automatic reset, phase failure sensitivity, and auxiliary contacts (1 NO + 1 NC) for signaling. Designed for direct mounting on SIRIUS contactors, it ensures space-saving assembly in control panels and motor starters.

Standard Features

  • 4.5–6.3 A adjustable range: Covers small motors — precise protection for 1.5–3 kW @ 400 V applications.

  • Class 10 tripping: Standard for motors with normal starting — inverse-time delayed overload protection.

  • Phase failure & unbalance detection: Built-in sensitivity — protects against single-phasing and asymmetric loads.

  • 1 NO + 1 NC auxiliary contacts: For signaling trip status or interlocking — manual or automatic reset selectable.

  • Direct contactor mounting: Fits S00 size contactors (3RT2) — quick assembly without extra wiring.

  • Global approvals: IEC/EN 60947-4-1, UL, CSA, CCC — accepted worldwide for motor control.
