Schneider LRD16 Industrial Control Relay TeSys LRD Series For LC1D Contactors
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:
- Protection against motor overload and loss of phase.
- The perfect complement of magnetic only circuit breakers to manage thermal protection for motors.
- Selectable manual, remote or auto reset tripping options for better process management.
Features
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.
Specifications:
- Manual or automatic reset
- Sealable flap
- Pre-wiring kit
- Direct mounting with TeSys D contactors
- Terminal block for separate mounting
- Remote electrical reset available as an option
- Connectors: spring terminal, screw clamp, terminal block EverLink (LRD3)
- Class 10 A & 20
