Product Description
LR9F series thermal relay is suitable for using in the circuit rated voltage up to 660V, ratedcurrent 93A AC 50/ 60Hz, for over-current protection of AC motor. The relay has the differentialmechanism and temperature compensation and can plug in CJX2 series AC contactor. Theproduct conforms to IEC60947-4-1 stardand.
LR9F series thermal overload relays are designed to use with contactors LC1-F115 to LC1-F330. In addition to the protection provided by modeled thermal overload relays LR9-F, they offer the following special features:
- Protection against phase imbalance
- Choice of starting class
- Protection of unbalanced circuits
- Protection of single-phase circuits
