6.8 Breaker Operations Count
Breaker Operations refers to the number of times the device has opened the breaker. The Breaker Operation function allows the setting of the breaker monitoring parameters.
The Sum of Interrupted Current is the total sum of the cur- rents that were interrupted by these breaker openings. The setpoint is triggered when any phase exceeds the set limit.

The Interrupted I (current) Function (3501) can be enabled or disabled. When enabled, the function generates an event (which can be matrixed to an output contact) when the inter- rupted current exceeds the pickup value. The interrupted current pickup value (3502) can be set to any value from 0 to 9999.90 kA in steps of 0.01 kA.
The Breaker Operations Function (3503) can be enabled or disabled. When enabled, the function counts the breaker operations since the last reset.
The Breaker Operations Counter (3504) can be set from 0 to 65535.
6.9 Hardware Status (Relay Data)
The Relay Data function provides additional hardware infor- mation on the ISGS relay, shows all set binary inputs and outputs, and displays a relay identification string.
The Circuit Name (7401) identifies a relay, breaker, bus, or feeder which your ISGS relay is protecting. This string (up to 16 characters) is
All circuit boards installed in your ISGS relay are provided with a serial number and a special identification number. These numbers can be displayed by accessing addresses 7403 to 7407.
Similar to the firmware version identification number of your ISGS relay described in Section 4.1, the serial and identifi- cation numbers of your main board and optional board(s) help Siemens track the versions and options available on your boards.
Binary Inputs (7408) displays the status of the binary inputs as illustrated in Figure 6.2. The status updates automatically as they change.
