Thermal overload relay RE27D-32 004642414

Thermal overload relay RE27D-32 – reliable circuit protection

The RE27D-32 thermal overload relay is a protective device designed to protect electric motors and other equipment from overload. Its function is to disconnect the circuit when the permissible current is exceeded, preventing damage and extending the life of connected receivers. This model, manufactured by ETI-POLAM, is characterized by a solid construction and precise operation, making it an ideal solution for both professional installers and end users.

Construction and application

The RE27D-32 relay uses a bimetallic strip that bends under the influence of rising temperature caused by excessive current flow. This in turn activates a mechanism that disconnects the main contact, interrupting the circuit. The mounting method – direct or independent – provides flexibility in choosing a solution for specific installation conditions. These types of thermal relays are widely used in:

• Electrical switchboards
• Control cabinets
• Industrial applications
• HVAC systems (heating, ventilation, and air conditioning)
• Protection of electric motors of various power

Characteristics and benefits

This model is characterized by a release class of 10, which means it is adapted to applications with moderate inrush current. The current setting range of 22…32 A allows for precise adjustment of the protection to the characteristics of the load. In addition, the presence of one auxiliary normally open contact and one normally closed contact enables integration with control and signaling systems.

• Overload protection: Provides effective protection of motors and other equipment against damage caused by excessive load.
• Precise adjustment: The current setting range allows you to adapt the protection to specific application needs.
• Versatile mounting: The possibility of direct or independent mounting facilitates installation in various conditions.
• Status indication: The presence of auxiliary contacts allows for remote monitoring of the device status and integration with control systems.
• Flat plug-in connection: Facilitates quick and safe connection of wires.
• Durable construction: Ensures long-lasting and reliable operation in demanding industrial conditions.
