Product details
The 858-20/078 by Qualtek pioneers Power Entry Connectors - Inlets, Outlets, Modules innovation for mining equipment. This explosion-proof connector delivers {Voltage - UL} voltage isolation in hazardous environments, specifically designed for underground coal mining applications where safety is paramount.Featuring IEC 320-C20 configuration, the connector meets MSHA 30 CFR Part 18 requirements. The flame-path design contains internal explosions.Designed as Receptacle, Male Blades, this solution employs silver-graphite contacts. The self-cleaning action prevents arc tracking in methane atmospheres.Rated for 16/20A at 40 C ambient, the connector exceeds IEC 60079-0 explosion-proof standards. The thermal mass design limits surface temperatures.The 125/250VAC insulation system withstands 4kV impulse tests. The ceramic barriers prevent tracking in dusty conditions.The Filtered (EMI, RFI) - Commercial design provides 40dB attenuation from 1MHz-100MHz. The intrinsically safe filters prevent spark generation.No configuration includes a flame-proof fuse chamber. The sand-filled design quenches arc energy.With 3 circuits, the connector supports mining machine power. Each contact maintains 15mm creepage distance.The Panel Mount, Flange system includes brass explosion-proof hardware. The tapered threads prevent accidental loosening.Featuring Quick Connect - 0.250" (6.3mm) technology, the connector accepts mining-grade cables. The compression seals prevent methane ingress.Precision Rectangular - 34.00mm x 26.00mm ensures proper flame-path engagement. The tapered interface prevents misalignment.Certified by CSA, UL, VDE for hazardous locations. The connector is approved for Class I Division 1 Group D atmospheres.
