Z Overload Relays

Z overload relays offer motor protection in the event of single phasing or overload. Their auxiliary contacts disconnect the motor  contactor and signal the fault. These relays can also be used for protecting EEx e motors.

The Z relays have been improved and modified for the new xStart system: engineering and inventory management have been facilitated by the reduction in the number of types.

Z thermal overload relays can be mounted directly on DIL M contactors up to 250 A. When required, the relay can also be installed separately
