This product is part of the Harmony XB4 and XB5 range, an offer of Ø 22mm pushbuttons, switches and pilot lights. It is a single contact block with silver alloy contact. It is only used in combination with an emergency stop pushbutton and is not compatible with other pushbuttons. It comes with 1 NC monitoring contact with slow break operation. The NC contact is opened when the emergency stop is activated. The monitoring feature triggers emergency stop due to improper installation. It comes with CE, CCC, UKCA, EAC, UL and CSA certification. This monitoring contact is compatible for emergency stops in both the XB4 and XB5 range. It connects to control circuits with simple screw-clamp connections. The Harmony XB4 and XB5 range offers innovative features for simple and efficient use.
