Europa TR2-D Thermal Overload Relay, 4-6A

The Europa TR2-D Thermal Overload Relay is a precision-engineered motor protection device designed to meet stringent international safety and performance standards. It offers reliable protection for electric motors by disconnecting the power supply in the event of an overload or phase failure, preventing costly damage and potential downtime. Its robust design and high-quality construction ensure dependable operation in a wide range of industrial and commercial electrical applications.

Key to its functionality is the adjustable current setting range of 4 to 6 Amperes, allowing for precise calibration to match the specific motor it is protecting. The relay features a tripping class of 10 (Class 10A), indicating its thermal response time. It boasts high electrical ratings, including an insulation voltage of 690V and an operational voltage of 600V, making it suitable for use in demanding environments. Furthermore, it offers excellent protection against phase failure, with a sensitivity that triggers at a tripping current 25% above the nominal current (In).

The unit is constructed with safety and durability in mind. It complies with VDE 0106 standards, providing IP2x protection against finger contact, and demonstrates high dielectric strength, withstanding 6kV at 50Hz and 6kV impulse voltage as per relevant IEC standards. Its compact dimensions facilitate easy installation in control panels and motor starter assemblies, saving valuable space.
