The PBX Secure direct-opening-action switch is said to guarantee contact opening and closing.

Its standard dimensions comply with standard DIN41636-6 form F and ensure that it can be integrated in any application.

The solution offers numerous onboard applications for inside and outside the rolling stock, including joystick controller, emergency stop, door opening, and medium-voltage circuit-breaker and braking-system applications.

The PBX Secure is used as an auxiliary safety contact for devices such as medium-voltage circuit breakers, motorised disconnect switches and ground-disconnect switches.

In the field of industrial lifting, the PBX Secure is suitable for position-detection requirements in the geared motors of lifting machinery.

The PBX Secure range complies with the following industrial and railway standards: BS EN 50124-1 (insulation coordination); NFF 16-101/102 (French Fire/Smoke standard): classification of housing materialcertified I2/F1; EN/IEC 60947-5-1 (switchgear for control circuits); and DIN 41 636-6 form F (standard on dimensions).

The PBX also has CE, UL, Csa and CCC marking, with VDE approvals available on request.

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.

Both of the switches component circuits are electrically isolated (form Zb).

The range offers two levels of sealing in two identically sized versions to provide an exact solution to integrators’ requirements: a standard IP40 version where the actuator is protected by a 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.

Potting points insulate the link between the terminals, the housing and the cover.

A range of accessories is available to add to the standard version, including a rollerlever, mounting plates, protective covers, and various types of terminal.
