T16-16 Thermal Overload Relay ABB 1SAZ711201R1047

The T16-16 Thermal Overload Relay by ABB (Product Code: 1SAZ711201R1047) is a device designed to protect electric motors from thermal overloads. Here’s a breakdown of its key features and specifications:

Key Features:

• Thermal Protection: The relay is designed to protect motors from excessive heating by monitoring the motor’s current and automatically disconnecting the circuit if it exceeds a preset value for a prolonged period. This helps to avoid overheating and potential damage to the motor.
• Adjustable Settings: It has an adjustable current setting, allowing it to be tailored to suit the motor’s specifications.
• Phase Failure Protection: In addition to protecting against overloads, it also provides phase failure protection. This ensures that the relay can detect if one or more phases of the power supply are missing or unbalanced, preventing potential motor damage.
• Manual Reset: After tripping, the relay often requires a manual reset before the motor can be restarted, ensuring that an issue is addressed before operation continues.
• Wide Current Range: The T16-16 model typically operates in a certain current range (e.g., 7.5 to 16A), making it suitable for a wide range of motor sizes.
• Compact Design: The relay is designed to be compact, which makes it suitable for installation in various electrical control panels or motor protection circuits.

Technical Specifications:

• Rated Current: 7.5 A to 16 A (adjustable).
• Voltage Rating: Compatible with typical AC voltage ranges, often up to 690 V AC.
• Trip Class: Typically, it falls under Class 10A (for motors requiring faster trip times) but can vary depending on the setting.
• Mounting: Can be mounted on a standard DIN rail for ease of installation.
• Reset Type: Manual reset after a trip event.

Applications:

• Electric Motors: The T16-16 Thermal Overload Relay is used primarily for the protection of motors in industrial and commercial applications. It is commonly found in pumps, fans, compressors, conveyors, and other machinery that use electric motors.

Compatibility:

• Motor Starters: It is typically used with motor starters and can be integrated with ABB’s range of contactors and other protection devices to form a comprehensive motor protection circuit.

Advantages:

• Reliability: ABB is known for producing reliable and durable electrical components, and this relay is no exception.
• Energy Efficiency: By protecting motors from overload conditions, it helps in maintaining efficient operation and preventing costly downtime.

This relay can be part of an overall motor protection and control system, working alongside other devices like motor starters and contactors for enhanced operational safety.
