TF42-16 Thermal overload relay 1SAZ721201R1047

Thermal overload relay for motor protection – reliable installation protection.

The TF42-16 thermal overload relay is a protection element designed to protect electric motors from overload and resulting damage. The device, also identified by catalog number 1SAZ721201R1047, provides a quick and reliable response in the event of exceeding the permissible current, protecting both the motor and the rest of the installation components. This relay is particularly useful in industrial applications where the risk of overloads is higher.

Construction and operating principle

The TF42-16 relay is characterized by a current setting range of 13 to 16 A, allowing precise matching to the load characteristics. It has a normally open (NO) and normally closed (NC) contact, enabling integration with control and signaling systems. Automatic reset after activation simplifies system restart after removing the cause of the overload. Made of high-quality materials, it ensures durability and reliability even in harsh working conditions. Direct mounting simplifies installation and minimizes space.

Key features and benefits

• Wide adjustment range: Adjustment in the range of 13-16A allows precise adaptation to the load.
• Automatic reset: Enables quick restoration of operation after removing the cause of the overload – saving time and minimizing downtime.
• Multifunctionality: Has NO and NC contacts for integration with control and failure signaling systems.
• Durable construction: Ensures long-lasting and reliable operation in demanding industrial conditions.
• Release class 10: Guarantees a quick response to overloads, protecting the motor from damage.
• Mounting method: Direct mounting simplifies installation and saves space in the control cabinet.
• Compliance with standards: Meets the requirements of IEC/EN 60947-1 standards, ensuring safety of use.
• Environmental resistance: Operation at temperatures from -25°C to +60°C allows use in various industrial environments.

The TF42-16 relay is a solid solution for installers looking for reliable motor protection and for end-users who value the safety and continuity of their equipment.
