OTDC200GV11-ESS ABB 200 A 2-Pole 1500 V DC Switch Disconnector

Why Choose the ABB OTDC200GV11-ESS 200 A 2-Pole 1500 V DC Switch Disconnector?

The ABB OTDC200GV11-ESS, order code 1SCA161987R1001, is a high-performance 200 A 2-pole DC switch disconnector designed for reliable switching and isolation in demanding 1500 V DC electrical systems. Part of the compact ABB OTDC S2.0 series, it is engineered for applications where high DC voltage, efficient switching and enhanced short-circuit performance are important.

The OTDC200GV11-ESS uses ABB's optimised two-pole 1500 V DC switching concept and provides a DC-21B rated operational current of 200 A. It is front operated with the operating mechanism positioned between the poles and uses a single switching circuit, making it particularly suitable for integration into photovoltaic equipment, DC distribution assemblies and other high-voltage DC systems.

The ESS version is specifically designed for higher short-circuit values and incorporates predetermined fuse-coordination options. It provides a rated conditional short-circuit current of 50 kA at 1500 V DC, together with a 10 kA short-circuit making capacity, giving equipment manufacturers a robust solution for high-performance DC isolation.

Enhanced Short-Circuit Performance for 1500 V DC Systems

The ESS designation identifies OTDC versions developed for installations requiring higher short-circuit performance. ABB provides predetermined fuse-coordination arrangements for these switches, allowing the OTDC200GV11-ESS to achieve a conditional short-circuit current of 50 kA at 1500 V DC when installed with an appropriate protective device selected according to ABB's coordination data.

This enhanced protection capability complements the compact two-pole architecture of the OTDC S2.0 platform. The result is a space-efficient 1500 V DC isolation solution particularly well suited to photovoltaic generation, power-conversion equipment and other installations where high prospective DC fault currents must be considered.

Typical Applications

• 1500 V DC photovoltaic power systems.
• Solar inverter and power-conversion equipment.
• PV combiner and switching assemblies.
• Renewable-energy power distribution systems.
• Industrial high-voltage DC distribution.
• DC control and power cabinets.
• Energy conversion and storage equipment.
• OEM electrical equipment requiring enhanced DC short-circuit performance.
