Description
About the Product
Lauritz Knudsen compatible ML 2/3 Thermal Overload Relay 13–21A 415V AC Class 10 is a motor protection device engineered to safeguard electrical motors from overload conditions. It is widely used in motor starter systems to ensure consistent & safe operation in industrial environments.
How the Mechanism Works
The relay operates using a thermal sensing mechanism that continuously monitors current flowing through the motor circuit. When the current exceeds the adjustable range (13–21A) for a defined duration, the internal thermal element heats up & trips, disconnecting the circuit to prevent motor overheating & damage.
Electrical Configuration
Rated for an adjustable current range of 13–21A & 415V AC supply, the relay incorporates Class 10 tripping characteristics. This ensures reliable & timely disconnection during overload conditions. It is typically used in combination with contactors in motor control panels.
• Safety / protection aspects
• The relay provides effective protection against sustained overload, helping prevent motor winding damage, excessive heat buildup, & potential system failures. It enhances operational safety & improves system reliability.
Construction & Design
A compact control module combines sensing or coil elements, switching contacts, adjustment or indication features, & accessible terminals.
Safety & Protection
Use within the stated ratings & coordinate the control circuit with suitable isolation & overcurrent protection before installation or service.
Mounting & Durability
Designed for seamless integration with compatible contactors, it supports standard panel mounting. The robust construction ensures durability & consistent performance in demanding industrial applications.
Application Domains
Suitable for medium to high-load motor applications such as pumps, compressors, conveyors, & industrial machinery requiring dependable overload protection.
Key Features
• Adjustable current range: 13–21A
• Rated for 415V AC operation
• Class 10 tripping characteristic for reliable protection
• Thermal overload sensing mechanism
