Breaker Tab

Universal Relay - Breaker Tab

The Breaker tab supports the B30, C30, C60, D60, F30, F35, F60, G60, L60, L90, M60 and T60 UR devices, and shows a variety amperage measurements and breaker status, as well as allowing control of breaker functions and auto reclosers.

Arcing

Amperage at Breaker 1 and 2 is displayed for Phases A, B, and C. The Clear Current Arcing functions allow current arcing conditions to be cleared.

Breaker Arcing Current features are available for Breakers 1 and 2. This element calculates an estimate of the per-phase wear on the breaker contacts by measuring and integrating the current squared passing through the breaker contacts as an arc. These per-phase values are added to accumulated totals for each phase and compared to a programmed threshold value. When the threshold is exceeded in any phase, the relay can set an output operand to "1". The accumulated value for each phase can be displayed as an actual value.

Breaker Functions

Breaker control can be enabled or disabled using these controls, and the Breaker Arcing Amp function can be enabled or disabled for Breakers 1 and 2. These controls will be disabled if the connected device does not support breaker control.

Breaker Status

Selecting a settings group changes the display of functions. Up to 8 settings groups are available for display.
