Why Choose the ABB MA1-8129 Blanking Plug?
The ABB MA1-8129 is a durable grey plastic blanking plug designed for ABB modular pilot-device enclosures and control stations. Supplied under ABB order code 1SFA611920R8129, it provides a simple and reliable way to close an unused 22 mm mounting hole where an operator or signalling device is not installed.
As part of the ABB MA1 pilot-device accessory range, the MA1-8129 is suitable for compatible ABB MEP and KEM series enclosures. Closing unused operator positions helps maintain a neat, professional control-station installation while protecting the opening from direct exposure to the surrounding environment.
