Product details
Qualtek's 858-20/077 establishes new benchmarks in Power Entry Connectors - Inlets, Outlets, Modules for railway applications. This vibration-proof connector delivers {Current - UL} current capacity while meeting EN 50155 shock and vibration requirements, making it indispensable for rolling stock power distribution systems.The IEC 320-C20 interface complies with UIC 652 standards. The double-locking mechanism prevents accidental disconnection under 5G vibration.Designed as Receptacle, Male Blades, this connector employs cold-welded contacts. The gas-tight joints prevent oxidation in humid environments.Rated for 16/20A at 70 C, the connector uses electrolytic copper contacts. The mass-termination design ensures uniform current distribution.The 125/250VAC insulation system withstands 3kV RMS for 1 minute. The graded insulation design prevents surface tracking.The Filtered (EMI, RFI) - Commercial topology provides 70dB attenuation from 10kHz-1GHz. The ferrite-loaded design suppresses traction motor noise.No configuration includes a vibration-resistant fuse clip. The nickel-plated contacts prevent fretting corrosion.With 3 circuits, the connector supports auxiliary power distribution. Each contact maintains 10mm creepage distance.The Panel Mount, Flange system includes M12 anti-vibration locknuts. The floating panel interface compensates for chassis flexure.Featuring Quick Connect - 0.250" (6.3mm) technology, the connector accepts 0.5-35mm conductors. The cage clamp design maintains constant pressure on fine strands.Machined to Rectangular - 34.00mm x 26.00mm tolerances, the flange provides EMI shielding. The conductive gasket achieves 80dB shielding effectiveness.Certified by CSA, UL, VDE for railway applications. The connector is qualified to EN 61373 shock and vibration standards.
