配方式空气系列的所有保护跳闸单元确保高可靠性，因为电子电路定期控制内部连接的连续性，如跳闸线圈、额定值插头和每个电流传感器（Ansi 74）。如果发生故障，led会指示相应的报警，以便于快速识别故障。

VM600 IOC4T：保护跳闸指示通过按iTest键激活，并且运行不需要外部电源，因为单元内部安装了电池。测试功能保护跳闸装置前面的测试端口可通过连接以下装置之一运行断路器测试：-EkipTT运行跳闸测试，LED测试并检查看门狗功能检测到的无报警；-EkipT&P不仅允许跳闸测试和LED测试，还允许运行个别保护功能测试并保存相关报告。

用户界面Ek 1提供了多种多样的阈值和跳闸时间，保护可以通过倾斜开关来设置。最多有5个led（取决于版本）可以指示正确的操作或警报。该接口始终能够清晰、快速地识别安装状态：正确操作（绿色LED)、过流预报警或报警、存在自控制功能报警、维护间隔过期、故障后跳闸保护指示。

All protective trip units in the Air series ensure high reliability, as electronic circuits regularly control the continuity of internal connections, such as trip coils, rated plugs and each current sensor (Ansi 74). If a fault occurs, the led will indicate the corresponding alarm to facilitate quick identification of the fault.

VM600 IOC4T: The protection trip indicator is activated by pressing the iTest key, and no external power is required for operation, as the battery is installed inside the unit. The test function protects the test port on the front of the trip device to run the circuit breaker test by connecting to one of the following devices: -EkipTT runs the trip test, LED tests and checks for no alarm detected by the watchdog function; -EkipT&P allows not only trip tests and LED tests, but also individual protection function tests to be run and reports to be saved.

The user interface EK-1 provides a wide variety of thresholds and trip times, and the protection can be set by tilting the switch. Up to 5 leds (depending on the version) can indicate the correct operation or alarm. The interface is always able to clearly and quickly identify the installation status: correct operation (green LED), overcurrent warning or alarm, the presence of self-control function alarm, maintenance interval expiration, trip protection indication after failure.
