Product environment

Sécheron’s RTP100 traction protection relay is a multifunctional programmable device to monitor traction parameters like voltage and current in AC or DC rail vehicles and to protect traction equipment from short circuits, overcurrents, and unsafe catenary supply voltages. If the parameters measured exceed the thresholds set, output relays connected in series with the main circuit breaker control circuit will be triggered, protecting the vehicle and passengers.

The RTP100 can also be coordinated with the Traction Control & Management System (TCMS) to detect the vehicle supply voltage. Users can easily configure the device using dedicated software. The RTP100 can be delivered with other Sécheron electrical safety components like AC and DC circuit breakers and voltage and current sensors.

All of our components and solutions are backed by Sécheron expert service during all phases of your project. Let us recommend the best solution to meet your needs. Whatever your choice, you can count on efficient support worldwide for the entire lifetime of your product.
