ABB GS Series Fuse Switch Disconnector with 100 kA Breaking Capacity Single Pole Safety Isolation

GSH201 ABB Fuse combined disconnector Integrated single pole safety isolation short circuit protection

Product Overview

ABB GSH201 is a single-pole Fuse Switch Disconnector in the ABB GS series, integrating electrical isolation and short-circuit protection functions. This product is specially designed for control circuits, single-phase loads and auxiliary power supplies. It provides reliable overcurrent protection through built-in standard NH/gG fuses and features clearly visible breakpoints to ensure the safety of maintenance operations. It is widely applied in industrial control cabinets, building power distribution, OEM equipment and new energy systems.

Key features

✅ isolation + protection in one

Achieve safety isolation and high-breaking short-circuit protection within a single compact unit, simplifying the system design.
✅ visible breakpoint, safe operation

The knife switch contact is fully exposed at the OFF position, providing a visible isolation break point in compliance with IEC 60204-1 standard.
The operation handle is equipped with a padlock hole and supports the LOTO (Lock and Tag) safety regulations to prevent misoperation.
✅ ultra-high breaking capacity

In combination with NH/gG fuses, the short-circuit breaking capacity can reach 100 kA (230 V AC), far exceeding that of ordinary circuit breakers.
✅ is flexible to install and highly compatible

Supports 35mm DIN rail mounting or panel screw fixation
Compatible with ABB standard NH fuses (such as 10× 38mm size)
The screw terminal wiring is reliable and compatible with common wire specifications
✅ globally certified, compliant and reliable

Compliant with IEC/EN 60947-3 (disconnectors) and IEC/EN 60269 (fuses)
Passed international authoritative certifications such as CE, CCC and TUV
