Description

The Siemens 3UW5102‑1J Overload Relay is a durable and reliable industrial protection device designed to safeguard electric motors and equipment from overload conditions. Engineered by Siemens for use with motor starters and contactor assemblies, this bimetal thermal overload relay delivers precise protection within a current range of 6.3 – 10 A, making it ideal for small to medium three‑phase motor applications.

Featuring bimetallic tripping technology, the 3UW5102‑1J detects excessive current and interrupts the circuit to prevent motor damage caused by overheating or prolonged overloads. It also incorporates single‑phase protection, adding an extra layer of safety for three‑phase systems prone to phase loss or imbalance.

Compact in size and easy to mount alongside compatible contactors, this thermal overload relay is widely used in industrial control panels, DOL (Direct On Line) motor starters, pump controls, and other automation solutions. Backed by Siemens quality, it ensures long service life and dependable motor protection in demanding industrial environments.

Key Features:

  • Designed for motor overload protection in three‑phase systems.
  • Wide current setting range: 6.3 – 10 A.
  • Bimetallic thermal tripping for accurate and reliable response.
  • Single‑phase protection to safeguard against phase imbalance.
  • Ideal for mounting with contactors in starters and control panels.
  • Compact, rugged design for industrial applications.
