What Makes Our Explosion-Proof Switches & Starters Industry-Compliant

What Makes Our Explosion-Proof Switches & Starters Industry-Compliant
  • Multi-Standard Certification – ATEX, IECEx, UL, and CSA approvals for worldwide acceptance

  • Advanced Protection Methods – Combining Ex d flameproof enclosures with Ex e increased safety components

  • Precision Engineering – CNC-machined flame paths and military-grade stainless steel construction

  • Smart Protection Features – Built-in arc suppression and thermal overload protection

  • Third-Party Validation – Annual recertification by TÜV and other notified bodies


Safety by Design: How Our Starters Prevent Ignition Risks

  1. Certified Protection: ATEX/IECEx-certified starters isolate sparks and heat, compliant with Zone 1/2/21/22 requirements for explosive gas/dust environments.

  2. Robust Construction: Cast aluminum or stainless steel enclosures (IP66/Ex d) withstand corrosion, impacts, and extreme temperatures (-30°C to +60°C).

  3. Fail-Safe Engineering: Integrated thermal overload cutoffs and arc-suppression circuits eliminate electrical fault risks.

  4. Smart Monitoring: Real-time diagnostics detect anomalies, triggering shutdowns to prevent hazardous conditions.

  5. Industry Proven: Trusted in oil refineries, chemical plants, and grain silos, ensuring operational continuity and compliance with NFPA 70/UL 1203.
