Eliminate Locomotive Downtime with Heavy-Duty OEM-Matching Contacts

When a locomotive enters the maintenance shop with worn contacts, standard electrical parts won’t suffice. Severe arcing can rapidly degrade surfaces, leading to catastrophic equipment failure. SHZHJ provides a permanent, year-round inventory of premium replacement contacts fully optimized for GE and EMD series heavy-duty contactors.

By mastering the precise mechanical alignment between fixed and movable contact assemblies and strictly adhering to OEM metallurgy standards, our parts are engineered to safely endure intense thermal energy during separation, transferring it efficiently into the arc chute assembly for rapid extinction.

Strict OEM-Specification Silver Contacts: Built entirely to original GE and EMD material and metallurgical standards. We match the exact raw material specifications required by the OEM to ensure identical arc-erosion resistance, preventing surface pitting and contact welding under heavy inductive loads.

Micro-Ohm Resistance Consistency: Engineered to align with original factory electrical engineering profiles. Each batch undergoes micro-ohm testing to guarantee low contact resistance, minimizing voltage drop and eliminating localized overheating to protect your core contactor assembly.

100% Drop-In MRO Integration: Perfect dimensions that match original GE/EMD blueprint specs exactly. No mechanical adjustments or alignment modifications needed—ready for zero-delay emergency fleet repairs.
