GSH204 ABB Disconnector with fuse protection Integrated safety isolation short circuit protection
Product Overview
ABB GSH204 is a 4-pole Fuse Switch Disconnector in the ABB GS series, integrating electrical isolation and short-circuit protection functions. This product is specially designed for industrial control cabinets, power distribution systems and motor terminal circuits. It provides reliable overload and short-circuit protection through built-in NH/gG type fuses, and also features visible breakpoints to ensure the safety of maintenance personnel during operation. It is widely applied in fields such as construction, energy, manufacturing and infrastructure.
Key features
✅ dual function integration
It simultaneously achieves electrical isolation (in compliance with
safety standards) and short-circuit protection (through fuses),
saving space and costs.
✅ high security design
The knife switch contacts are fully exposed at the OFF position,
providing a visible break point and meeting the mandatory
requirements of IEC 60204-1 for "safety isolation".
The operation handle is equipped with a locking hole and supports a
padlock (LOTO) to prevent accidental closing.
✅ high judgment ability
In combination with NH/gG fuses, the short-circuit breaking
capacity can reach 100 kA (400 V AC), far exceeding that of
ordinary circuit breakers.
✅ modularization & flexible installation
Standard DIN rail or panel mounting (optional base plate)
Supports front wiring or rear wiring (depending on the installation
method)
Compatible with ABB standard NH fuses (such as 10× 38mm or 14×
51mm)
✅ global certification compliance
Compliant with IEC/EN 60947-3 (disconnectors) and IEC/EN 60269
(fuses)
Passed international certifications such as CE, CCC and TUV

Typical application scenarios
Industrial automation
It is used for the starting, stopping and protection of
medium-voltage motors, such as water pumps, fans, compressors and
other equipment.
Power transmission and distribution
Load switching and protection in scenarios such as medium-voltage
switch cabinets and substations.
Energy and infrastructure
Auxiliary control of photovoltaic inverters, pumping stations of
water treatment plants, and backup power switching systems.
OEM equipment integration
As a standard component embedded in the OEM control cabinet, it
enhances the reliability of the entire machine.
