FAQ

Q: What safety features prevent electrical faults in this high-voltage plug?
A: The plug is engineered with full phase-to-phase segregation with earth, single-piece contacts that eliminate hot joints, and full solid earth connectivity throughout the product. It meets rigorous AS/NZS 1299, IEC 60079-0, and IEC 60079-1 compliance standards for explosive atmospheres.

Q: What are the short-circuit fault and voltage withstand ratings for the Ausproof RS1561?

A: This 425A plug is rated for operating voltages from 660V up to 3300V, successfully passing two phase-through fault tests of 25.0kA for 0.2 seconds and an AC high-voltage phase withstand test of 8.6kV for one minute.

Link your heavy-duty extraction machinery safely by pairing this high-voltage plug with a matching industrial receptacle rated for hazardous area deployment.

When setting up main power distributions across your industrial site, terminate your heavy-gauge power cables using these certified flameproof fittings to maintain high-amperage circuit integrity.

For data logging or system monitoring lines running parallel to your underground power feeds, secure the telemetry links with a rugged ethernet m12-to-rj45 cable to safeguard against signal degradation.
