ABB 5SHY3545L0003 Technical specifications​

Rated voltage (Ue): 7.2kV AC

Rated current (In): 200A

Breaking capacity (IEC): 63kA (7.2kV AC)

Fuse type: Full range protection (aM/gF)

Time-current characteristics: Fast blow (≤1ms response)

Installation method: Bolt fixing, suitable for standard base

Material and protection: Ceramic tube body, arc-resistant shell

Mechanical life: Single action, not reusable.

High Power Handling: Supports 4.5 kV/3,500 A for heavy-duty industrial applications, with a surge capacity 20% higher than standard thyristors.

Reliability: MTBF of 200,000 hours (per ABB testing), with vibration resistance (5 g) and humidity tolerance (95% non-condensing).

Energy Efficiency: Low forward voltage drop (1.5 V at rated current) reduces power losses by 15% compared to older generations.

Modular Design: Stackable configuration allows easy scalability for systems requiring 10–100 MW power output.

Purpose:ABB 5SHY3545L0003 is a high voltage fuse, belonging to the ABB SACE FHH series, designed for ​overload and short circuit protection of high voltage power systems (medium voltage field). Its core function is to quickly disconnect fault currents and protect transformers, motors, capacitors and other equipment from damage.

Application:Power transmission and distribution: transformer and line protection in substations and ring main units. Industrial energy: protection of high-voltage motors and capacitor banks in steel plants and chemical plants. Renewable energy: overcurrent protection of wind power converters and photovoltaic boost systems. Rail transit: DC/AC side protection of traction power supply systems.
