FAQ

What is the difference between a Class 10A and Class 20 overload relay?

A Class 10A relay, like the LRD3365, will trip within 10 seconds at 7.2 times the set current, making it suitable for standard motor starts. A Class 20 relay allows for a longer starting time (up to 20 seconds) and is used for motors with heavy loads or high inertia starts.

How do I correctly set the current on the LRD3365 dial?

The dial should be set to the motor’s full-load ampere (FLA) rating, which is found on the motor’s nameplate. Setting it correctly ensures the motor is protected without causing nuisance tripping.

Can this LRD3365 be mounted separately from a contactor?

Yes, while it is designed for direct mounting on LC1D80/95 contactors, it can also be mounted separately on a DIN rail using a specific terminal block adapter, such as the LA7D3064.
