LR3D3363 Schneider Electric Industrial Automation Components

Schneider Electric LR3D3363 Schneider Electric LR3D3363 is a non-differential thermal overload relay designed for unbalanced networks, classified under the LR3D sub-range. It features a direct connection to the contactor for upstream connections and screw-clamp terminals for both outgoing cables and the control circuit. This 3-pole relay is engineered to provide protection with settings adjustable for thermal overload from 63 to 80A. It includes 1 Normally Open (NO) and 1 Normally Closed (NC) auxiliary contacts for enhanced control flexibility. The LR3D3363 is rated for a phase-to-phase voltage of up to 690 V (0-400Hz) and supports a minimum current of 63 A and a maximum current of 80 A.
