LR9-F series three-pole thermal overload relays… are standard thermal relays for protecting motors in the setting range from 30 to 630A in 8 sub-ranges.
Relay LR9F5367 CLASS10 range 60-100A typical for LC1F115-LC1F185 contactors
Relay LR9F … protects motors against:
– heat overload,
– phase loss,
– chronic riots,
– long states of rotor inhibition.
