The ZGW1-1.5/6000 is a 1.5kV DC, 6000A high-capacity outdoor seccionador built for high-current metro and urban rail DC traction power supply systems. It provides electrical isolation where very high load currents must be carried and interrupted safely.
Designed with reference to IEC 61992-3 and metro DC traction power supply technical conditions, the switch uses a dedicated DC arc-extinguishing contact system to ensure reliable breaking at corriente nominal. The galvanizado en caliente steel structure and high-strength insulation support long-term outdoor service from -40°C to +70°C at altitudes up to 4,000 m.
Typical installation is inside traction substations or in trackside boxes along the line. Motorized and manual operating mechanisms are both available, allowing integration into automated SCADA-controlled networks or simpler manual installations.

Frequently Asked Questions
When is the 6000A version required?
On metro lines whose DC traction network sections carry very high currents — typically near substations or on heavily loaded corridors — the 6000A rating provides the required current capacity and breaking reliability.
Which standard applies?
Designed with reference to IEC 61992-3 (DC seccionadors for railway fixed installations) and metro DC traction technical conditions.
Can it be integrated into SCADA systems?
Yes, with the motorized operating mechanism the switch supports remote control and SCADA integration.
