    The sealable cover can be used to secure the actuators (rotary buttons and sliding switches) of the monitoring relays against unauthorized or unintentional manipulation. Siemens also offers a sealable membrane (3TK2820-0AA00) with a width of 22.5 mm for securing the monitoring relays. The sealable membrane is affixed to the front of the device and secures rotary buttons and sliding switches against unintentional operation.
