Thermal overload relays, For contactor mounting - Class 10 - Screw Terminals - 3MU7110-0MA0

Product Description

Siemens Thermal Overload Relay – Class 10, Screw Terminals – 3MU7110-0MA0

The Siemens 3MU7110-0MA0 is a thermal overload relay from the SINOVA 3MU7 series, designed for motor protection against overload and phase failure. It is intended for direct mounting on Siemens 3MT7 contactors, providing reliable protection for small to medium three-phase motors in industrial control systems.

This relay operates on a Class 10 tripping characteristic, meaning it provides fast and precise protection for motors with normal starting conditions, ensuring safe disconnection during overload situations before damage occurs.
