About the Product
Lauritz Knudsen compatible MN 2 Thermal Overload Relay 14–23A 415V AC Class 10A is a motor protection device designed to safeguard medium power motors from overload conditions. It is widely used in motor starter systems for efficient & safe operation.
How the Mechanism Works
The relay operates using a thermal sensing mechanism that continuously monitors the current flowing through the motor circuit. When the current exceeds the adjustable range (14–23A) for a specified duration, the internal thermal element heats up & triggers tripping, disconnecting the circuit to prevent overheating & motor damage.
Electrical Configuration
Rated for an adjustable current range of 14–23A & 415V AC supply, this relay features Class 10A tripping characteristics, ensuring faster & reliable response during overload conditions. It is typically used with contactors in motor control panels.
• Safety / protection aspects
• The relay provides effective protection against sustained overload conditions, helping prevent motor winding damage, excessive heat buildup, & system failures. It enhances operational safety & improves 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 integration with compatible contactors, the relay supports panel mounting in industrial setups. Its robust construction ensures durability & consistent performance under medium-load operating conditions.
Application Domains
Suitable for medium current motor applications such as pumps, compressors, conveyors, industrial machines, & automation systems requiring dependable overload protection.
Key Features
• Adjustable current range: 14–23A
• Rated for 415V AC operation
• Class 10A tripping characteristic for faster overload protection
