Schneider LRD16 Industrial Control Relay TeSys LRD Series Overload Protection Relay For LC1D Contactors
Application:
TeSys LRD is a flexible range of thermal overload relays from 0.06 kW to 75 kW. Designed for TeSys D contactors ranges, they can be mounted directly under the contactors for compactness or separately using accessories.
TeSys LRD relays are used across industry, infrastructure, building, etc., to provide:
TeSys LRD is a reliable series of thermal overload relays designed to cover a range of motor ratings up to 75kW at 400 V. The devices can be combined with TeSys D contactors to form an extremely compact starter.
