Railway sector: Crouzet is on track


ctively involved in the railway equipment sector, Crouzet has built up a solid reputation of a reliable manufacturer of safety critical components, which are widely used in the various rolling stock segments and some fixed installations.

Alstom, Bombardier, Faiveley Transport and many other leading manufacturers in the railway industry all over the world rely on us to provide them with high quality switching and detection solutions that are fully tested and engineered to their exact requirements.

PBX Secure switch guarantees contact opening & closing

The PBX Secure is a safety switch that guarantees the forced opening of contacts, even in the event of a short circuit and/or welding due to an overcurrent.

PBX Secure for the Railway industry

Designed for the most severe environments

The solution with operating temperatures from -50°C to +85°C, offers numerous onboard applications for inside and outside the rolling stock. The PBX Secure switch is used as an auxiliary safety contact for devices including joystick controllers, emergency stop, door opening, braking systems, medium-voltage circuit breakers, motorized disconnect switches and ground disconnect switches. In the field of industrial lifting, it is suitable for position-detection requirements in the geared motors of lifting machinery.

Standards & approvals

Our PBX Secure switches, sealed microswitches and limit switches are compliant with railway standards such as fire/smoke, vibration/shock resistance and electrical behavior & are approved by SNCF, the French national state-owned railway company which manages the rail traffic in France.

The PBX Secure range complies with the industrial and railway standards: BS EN 50124-1 (insulation coordination) & NFF 16-101/102 (French Fire/Smoke standard), classification of housing material certified I2/F1; EN/IEC 60947-5-1 (switchgear for control circuits); and DIN 41 636-6 form F (standard on dimensions). The PBX security switch also has CE, UL, Csa and CCC marking, with VDE approvals available on request. Its mechanism, patented and proven (EP 11227362), is in compliance with IEC 60947-5-1 annex K standard.

10 million switching cycles
 Its long overtravel ensures reliable switching event after long period of use.

Modular design

The modular design of this range means that many different configuration are possible. Depending on the purpose for which it is being used, the PBX secure switch can be fitted with either a plug or srew-type output, with a protective cover, normal or low breaking capacity, for installation in a round hole or slit, and with a roller lever actuator.

Two levels of sealing

The range offers two levels of sealing in two identically sized versions to provide an exact solution to integrators’ requirements. Products are available in a standard IP40 version with the actuator protected by membrane and an IP67 version that integrates a one-piece component comprising a membrane and a seal to protect the actuator and the mechanism respectively.
Our products are available both for original equipment and the aftermarket. Fast response times and our capacity for to innovate allows us to meet the customer’s exact requirements, with projects monitored from the specification stage through to product design, all over the world.
