It provides a stable housing for the discharge rod, ensuring it is always within reach of the operator who has de-energized the line.

SECURE BOX creates the interconnection between the switch, the grounding device, and the contact line.

SECURE BOX increases the safety level of the depot during maintenance activities.

The correct use of the SECURE BOX device allows for safe access to walkways and the use of equipment.

In compliance with procedures, this step prevents re-energization without returning the discharge rod to the SECURE BOX housing, thereby protecting the contact line.

SECURE BOX was developed from the need to remind the operator responsible for de-energizing the contact line of the essential step of short-circuiting the line downstream of the earth-blade switch.

Once maintenance operations on the rolling stock are completed, SECURE BOX requires the operator to remove the short-circuiting device from the contact line.

By returning the discharge rod to its housing and closing the door, the operator can retrieve the key required to enable the operating winch for closing the switch.

SECURE BOX is typically used in depots equipped with workstations where electric traction can be de-energized on-site via an earth-blade switch.

As required by the RFI DTC P SL 03 1 0 specification, all potential power sources must be short-circuited; therefore, in a depot with a double entrance, two SECURE BOX units must be positioned near the entrance or exit.

Both devices are linked by a key interlock system that interacts with the blade switch and other specialized equipment within the shed, such as overhead cranes, walkway access, wheel drops, lifts, etc.

Easy to handle, versatile, and practical, SECURE BOX is a component that integrates easily into existing workflows.

The device’s compact size and the absence of additional weight on the discharge rod make it dynamic and practical.

SECURE BOX is supplied with two types of keys, with a choice between Heavy Duty and Light Duty, from AREL, a leader in the interlocking sector.

This allows SECURE BOX to integrate well with any existing key interlock systems.
