Product details
The S31S55A by Altech Corporation 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 Pin and Sleeve (2P3W) configuration, the connector meets MSHA 30 CFR Part 18 requirements. The flame-path design contains internal explosions.Designed as Plug, Male Pins, this solution employs silver-graphite contacts. The self-cleaning action prevents arc tracking in methane atmospheres.Rated for 16A at 40 C ambient, the connector exceeds IEC 60079-0 explosion-proof standards. The thermal mass design limits surface temperatures.UL-listed for 20A makes this connector suitable for continuous miners. The silver-oxide contacts resist arc erosion.UL-recognized for 480VAC operation, the connector meets UL 1203 explosion-proof requirements. The threaded joints maintain flame-path integrity.The Unfiltered - 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 Free Hanging (In-Line) system includes brass explosion-proof hardware. The tapered threads prevent accidental loosening.Featuring Screw technology, the connector accepts mining-grade cables. The compression seals prevent methane ingress.The Chemical Resistant, Cord Grip, Impact Resistant, Push-Twist Lock, Strain Relief package includes integrated ground continuity monitoring. The pilot circuit detects shield breaks before power is applied.The UL94 V-2 material meets MSHA flame resistance requirements. The non-sparking alloy prevents ignition.IP67 - Dust Tight, Waterproof rating ensures reliable operation in water-filled shafts. The connector withstands 10 bar water pressure.Certified by cULus for hazardous locations. The connector is approved for Class I Division 1 Group D atmospheres.
