LR9F7581 Schneider Electric Electronic Components

Schneider Electric LR9F7581 Schneider Electric LR9F7581 is an electronic thermal overload relay designed for advanced protection with a rated current range of 380-630 A. It features a 3-pole configuration and offers connection types including upstream and outgoing cables via lugs and a control circuit through a screw-clamp. This part of the LR9F sub-range provides protection functions classified as Class 20, ensuring precise response to overload conditions. The LR9F7581 is equipped with 1 Normally Open (NO) and 1 Normally Closed (NC) auxiliary contacts for comprehensive circuit control. It operates on a supply voltage of 24 V DC and supports a rated voltage for AC phase-to-phase connections at 1000 V (50/60Hz). The protection settings for thermal overload are adjustable within the range of 380-630A, accommodating a minimum current of 380 A and a maximum current of 630 A.
