Schneider Electric LRD Series Overload Relay, 2.5 to 4A FLC Motor Rating, 4A Contact Current Rating - LRD08

This overload relay is a compact thermal protection device designed to safeguard motors in various applications. With dimensions of 66mm in height, 45mm in width, and 70mm in depth, it fits seamlessly into standard control systems. It operates effectively within a temperature range of -20 °C to +60 °C and offers a high current rating suitable for motor protection.

Features & Benefits

• Supports FLC motor ratings between 2.5A and 4A

• Features automatic and manual reset mechanisms

• Designed with a robust 3P configuration for enhanced reliability

• Offers a contact voltage rating of up to 690V AC

• Equipped with screw terminals for secure connections

• Complies with thermal overload class 10A for effective motor safeguarding

Applications

• Used for motor protection in diverse AC and DC networks

• Compatible with various contactor models for flexibility

• Ideal for electrical panels requiring efficient thermal relay solutions

• Employed in industrial automation processes to prevent motor damage

How does the tripping mechanism work during motor overload situations?

The tripping mechanism is designed to activate once the current exceeds 130% of the rated current on two phases, ensuring immediate protection of the motor from potential damage.

What type of connections are supported for control circuits?

The relay supports screw clamp terminals for control circuits, accommodating flexible cables of 1 to 2.5mm² without cable ends for easy installation and maintenance.

What are the implications of its IP20 rating?

An IP20 rating indicates that the device is protected against solid objects exceeding 12mm but does not offer protection against water, making it suitable for dry indoor environments.

How can temperature variations affect the performance of this relay?

The relay operates reliably between -20 °C and +60 °C, ensuring proper function across typical operational conditions without derating.

What is the benefit of using multiple auxiliary contacts?

Having two auxiliary contacts allows for enhanced circuit control, providing additional functionalities such as signalling and integration into larger control systems.
