Europa TR2-D Thermal Overload Relay 5.5-8A

Europa TR2-D Thermal Overload Relay provides motor protection with an adjustable trip setting from 5.5 A to 8 A.

The relay safeguards electric motors from damage caused by excessive current or phase failure. It operates on a thermal principle, disconnecting the circuit when a sustained current draw above its adjustable setpoint is detected, which helps prevent overheating and motor burnout.

Overview

This relay is designed to meet stringent international safety and performance standards, including IEC 60947-1, IEC 60947-4-1, NFC 63-650, VDE 0660, and BS 4941. It offers an insulation voltage of 690 V and an operational voltage of up to 600 V, making it suitable for a wide range of industrial and commercial applications.

Key Features

• Adjustable setting range: The current trip setting is adjustable from 5.5 A to 8 A to match the motor's full-load current.
• Tripping class 10: Indicates the trip time under overload conditions, suited to motors with standard starting characteristics.
• Phase failure sensitivity: Initiates a trip when current exceeds 25% above the nominal set current (In), protecting the motor against single-phasing damage.
• Defined tripping threshold: Tripping threshold factor of 1.14 ± 0.06In.
• High-frequency capability: Operates within frequency limits of up to 400 Hz.

Protection Ratings

The IP2x rating (to VDE 0106) provides basic protection against finger contact with live parts. The unit has a dielectric strength of 6 kV at 50 Hz per IEC 255-5 and a 6 kV impulse withstand voltage per IEC 801-5, supporting reliable operation in electrically noisy environments.
