Schneider LR9F5371 Industrial Control Relay TeSys Types Overload Relay Up to 630A For LC1F Contacors
Applications
TeSys LR9 is a complete range of electronic thermal overload relays from 0.1 to 360 A . Designed for TeSys D and F contactors ranges, they can be mounted directly under the contactors for advanced motor protection.
Features
Features
LR9F
• 8 current ranges from 30 to 630A
• Direct mounting to LC1F115-630 contactors
Simplified version:
• Class 10, Class 20
Complete version:
• Class 10, 20 selectable
• Alarm function to avoid tripping by load shedding
• Three-phase and single-phase applications
All versions offer:
• Settings locked by sealing the transparent flap
• Screw terminals
Benefits
Electronics harnessed for motor starters. These ingenious electronic overload relays offer a wide current adjustment range and a high level of accuracy due to thermal modeling suitable for even the most demanding applications. They can be directly mounted to TeSys D and F contactors to form extremely compact motor starters.
