Siemens SIVACON S8 & S4 Power Distribution & MCC Up to 7000A.
PT. Prastiwahyu Tunas Engineering is an authorized technology partner fabricating Siemens SIVACON S8 and S4 low voltage switchboards and intelligent Motor Control Centers (MCC). Designed for maximum plant uptime and personnel safety, SIVACON provides main busbar ratings up to 7000A, short-circuit withstand up to 150kA, and fully withdrawable motor starter drawers with criteria 1–7 internal arc containment.
Siemens SIVACON S8 Engineering Architecture & 7-Bay Layout.
Incoming Bay with SENTRON 3WL (Up to 7000A)
Air Circuit Breakers engineered for high breaking capacity up to 150kA. Equipped with electronic trip units (ETU), integrated Modbus/PROFINET communication, and motorized draw-out mechanisms.
Withdrawable Motor Control Drawers
Ergonomic drawer units with test, disconnected, and operating positions. Patented contact system allows live replacement of motor starters without interrupting neighboring units or busbars.
Symmetrical Top/Rear Busbars (Up to 150kA)
Electrodynamically optimized main busbar runs configured at top or rear, providing outstanding dynamic short-circuit strength, natural heat dissipation, and zero-maintenance busbar bridges.
Strip-Type 3NJ6 Disconnectors & PFC Bay
High packing density fuse switch disconnectors for sub-distribution, isolated vertical wireway chambers, and built-in automatic power factor correction (PFC) capacitor banks.

Critical Infrastructure for Siemens SIVACON.
Severe Duty Process Industries
Arc-resistant construction tested strictly to IEC 61641 criteria 1 through 7. Guarantees complete operator protection against catastrophic arc flash incidents in volatile processing zones.
Power Plant Auxiliary Distribution
High short-circuit withstand up to 150kA / 1s with heavy copper main busbars up to 7000A feeding critical turbine cooling pumps and emergency backup systems.
High-Speed Automated Packaging Lines
Withdrawable SIVACON MCC drawers enable instantaneous swap-out of motor drives in less than 3 minutes without shutting down main distribution lines.
Tier IV Data Center Facilities
Seamless digital integration via PROFINET and Modbus TCP for complete power telemetry, breaker status, and harmonic waveform capture directly into DCIM suites.
