Form 4b Internal Segregation & 100kA Short-Circuit Withstand.

PTE supplied IEC 61439 type-tested switchboards with Form 4b segregation, IP54 enclosure rating, and premium electroplated copper busbars engineered for harsh operating environments.

PTE engineered and manufactured custom Schneider Prisma iPM Form 4b switchboards with 100kA short-circuit withstand, IP54 dust/vapor protection, and anti-corrosive tin-plated copper busbars at our Cikarang manufacturing facility.

From complexity to measurable impact.

All switchboard assemblies underwent comprehensive factory acceptance testing (FAT) witnessed by client engineers, verifying flawless temperature rise control, dielectric insulation, and protection relay selectivity.
