Selection Notes
The legend holder printed EMERGENCY STOP is what sets this apart from the unmarked XALK178: pick the H29 variant wherever a visible function label is required on the panel itself rather than relying on button colour and shape alone. Contact configuration, reset mechanism and IP rating are otherwise identical.
