NBS40 – Passenger alarm devices
Emergency brake handle for rail vehicles
The electric emergency brake handle NBS40 enables the passenger to release an emergency stop. Its conspicuous outward appearance is a quick reference point for the passenger even in a stress situation.
High-quality switching elements characterised by positive opening operation, self-cleaning contacts, and high shock and vibration resistance guarantee years of uninterrupted operation.
With its elegant and yet rugged design, this emergency brake handle is not only suitable for rail vehicles running in commuter and main-line rail service, but also for industrial applications like escalators and passenger conveyors.
