FORM 4 SOLUTION

In industrial settings, workplace safety and efficient operation of facilities are of critical importance. At Tekpan PDS, we provide high-security, modular, and tested panel systems for your facility’s power distribution and control needs.

Our products are fully compliant with IEC 61439-1&2 standards and, with additional testing, comply with UL 891. Thanks to the Form 4 structure, safe maintenance, operational continuity, and fault isolation are ensured.

What is the IEC 61439-1&2 Standard?

• IEC 61439-1: General rules and performance requirements.
• IEC 61439-2: Specific rules for power distribution panels.
• The standard defines the verification tests expected from the manufacturer, including criteria such as mechanical strength, temperature rise, dielectric properties, short-circuit withstand, and protection classes.
• Purpose: To produce safe, high-quality, traceable, and comparable panel solutions.

Tests and Verifications

• Temperature rise test
• Dielectric withstand test
• Short-circuit withstand test
• Protection class (IP) test
• Mechanical impact resistance (IK) test
• Ground continuity test

Definition of Form 4 Structure

• Form 4 is a panel design class where functional units (e.g., switches, measuring devices, busbars) are completely separated from each other and from the busbar.
• It ensures independent operation from live parts during maintenance and faults.

Advantages of Form 4 in Industrial Applications

• High operational continuity
• Enhanced personnel safety
• Easy maintenance and fault isolation
• Flexible modular structure: adaptable to changing production lines
• Energy efficiency and optimized cable management

Application Areas

• Power generation facilities
• Petrochemical and refinery plants
• Cement and iron-steel factories
• Automotive production lines
• Water treatment and pumping stations
• Food and pharmaceutical manufacturing facilities
