FAQ

This thermal overload relay block is designed for direct mounting on Telemecanique (now Schneider Electric) TeSys D series contactors, specifically models like the LC1D09, LC1D12, LC1D18, LC1D25, and LC1D32.

The trip current is set using the dial on the front of the unit. The adjustment range for this specific model is from 10 Amperes to 16 Amperes. The dial should be set to the full load current (FLA) of the motor it is protecting.

The red button is a stop button that manually opens the normally closed (NC) trip contact, effectively stopping the motor. The blue button is used to reset the relay after it has tripped due to an overload condition. It can typically be set to either manual or automatic reset mode, depending on the specific model configuration.
