Thermal overload relay RE27D-2.8 004642405

Thermal overload relay – reliable motor protection

The RE27D-2.8 thermal overload relay is a protective device designed to protect electric motors from overload. This device, manufactured by ETI Polam, is widely used in industrial and commercial installations where reliability and safety of equipment operation are crucial. Its main task is to monitor the current flowing through the motor and disconnect the power supply if the permissible value is exceeded, thereby preventing its damage.

Construction and application

The RE27D-2.8 relay is characterized by a current setting range of 1.8 to 2.8 A, making it an ideal solution for motors with power adapted to this range. It has a flat plug-in connection for the main contacts, which facilitates assembly and replacement. Thanks to the possibility of direct or independent mounting, it can be easily integrated with the existing infrastructure. Equipped with one normally open and one normally closed auxiliary contact (1NO + 1NC), it allows for signaling the device status and integration with control systems. Class 10 release ensures appropriate time-current characteristics, protecting the motor against the effects of short-term overloads, such as those occurring during start-up.

Key features and benefits

• Wide current setting range: Allows adaptation to different motor loads (1.8…2.8 A).
• Universal mounting: Possibility of direct or independent mounting facilitates integration with various systems.
• Status signaling: The presence of auxiliary contacts (1NO + 1NC) allows monitoring of the device status and integration with control systems.
• Release characteristic of class 10: Provides effective protection against overloads while taking into account short-term current surges during motor start-up.
• Compatibility: Designed to work with the CEM9…CEM25 series – which makes it easier to select the appropriate protection for a specific application.
• Solid construction: Guarantees long-lasting and trouble-free operation in demanding industrial conditions.

The RE27D-2.8 thermal overload relay is a reliable solution for installers and users looking for effective protection of electric motors against overloads. Its versatility and ease of installation make it an ideal choice for both new installations and modernization of existing protection systems.
