Unlike Alternating Current (AC) which naturally crosses zero potential 100 or 120 times per second—allowing electric arcs to extinguish spontaneously—Direct Current (DC) maintains constant voltage and current intensity. When switching high DC voltages above 48V under heavy load, an intense electric plasma arc forms between opening contacts. Without active magnetic blowout or hermetic gas quenching, this plasma arc reaches temperatures exceeding 4,500°C, causing rapid contact erosion, terminal vaporization, and catastrophic phase-to-phase short circuits.
Our High-Voltage DC Contactors (HVDC) utilize a ceramic-to-metal or epoxy-sealed chamber injected with a pressurized inert gas mixture (typically Hydrogen and Nitrogen). Hydrogen possesses exceptional thermal conductivity at elevated plasma temperatures, cooling the electric arc rapidly. Combined with permanent magnetic blowout coils installed adjacent to the contact gap, the Lorentz force ($F = q(E + v \times B)$) physically drives the arc outward into arcing chutes, lengthening and extinguishing the plasma channel in milliseconds.
Technical Superiority Insight: Traditional open-air DC switches degrade rapidly in high humidity or coastal salt-fog environments. By enclosing contact assemblies inside gas-filled ceramic chambers, our contactors eliminate contact oxidation, prevent explosive atmospheric ignition in hazardous sites, and maintain stable contact resistance across hundreds of thousands of switching cycles.

Supporting the Port of Hamburg, Northern Germany wind energy networks, municipal transit electrification, and logistics hubs with heavy-duty switching hardware.
Container terminals across Altenwerder and Waltershof are implementing high-voltage shore power systems to eliminate vessel auxiliary diesel emissions. Our 400A–500A 1000V DC contactors provide rapid emergency disconnect units within shore-to-ship DC conversion sub-stations, maintaining galvanic isolation under marine environment stresses.
As Hamburg expands its public EV charging master plan along the A1 and A24 autobahn freight routes, ultra-fast 350kW+ DC charging cabinets demand robust switching. Our epoxy-sealed contactors reliably break continuous 300A–400A loads, preventing contact welding during high-current vehicle handshake sequences.
Grid operators managing offshore wind landing points near Hamburg utilize modular battery energy storage systems (BESS) for grid frequency stabilization. Altran HVDC contactors act as primary string disconnect relays, isolating fault paths in battery racks within 15 milliseconds.
Hamburg’s automated logistics warehouses rely on 48V–120V high-current electric forklifts and AGVs. Our compact DC contactors handle frequent stop-and-go current surges without thermal runaway, extending vehicle uptime across demanding multi-shift operations.
Manufacturing plants in industrial zones like Harburg require specialized DIN rail DIN EN 60947-4-1 contactors and solid state relays to manage heavy thermal processing ovens, extruders, and motor drives operating under tight European efficiency directives.
Navigating DIN EN, IEC/EN 61810-10, CE directives, and sustainability benchmarks across Northern European markets.
With the European Union’s AFIR framework taking direct legal effect across Germany, fast-charging infrastructure along the Trans-European Transport Network (TEN-T) corridor crossing Hamburg must support megawatt-level capabilities. High-voltage switching components inside these stations must comply with strict thermal dissipation limits and offer bidirectional breaking capacity to accommodate Vehicle-to-Grid (V2G) power flows.
European design engineers mandate explicit compliance with IEC/EN 61810-10 (Electromechanical elementary relays - High-voltage DC application requirements). Our components undergo extensive testing under overload, short-circuit, and dielectric withstand regimes to provide seamless approval pathways for OEMs seeking CE, TÜV, and VDE system-level certifications.
European supply chains enforce absolute traceability on dangerous substances. All materials utilized in Altran Magnetics contactors—from silver-alloy contact tips to epoxy encapsulation resins—strictly adhere to EU RoHS directives and REACH registration frameworks, ensuring long-term compliance without risk of sudden chemical phase-outs.
