Why Choose the ABB OT2500E40-135 Switch Disconnector?
The ABB OT2500E40-135, order code 1SCA162885R1001, is a heavy-duty 2500 A 4-pole switch disconnector engineered for high-current DC isolation applications at up to 1500 V DC. Part of ABB's OT -135 switch-disconnector range, it is designed for demanding battery energy storage, photovoltaic, inverter and industrial DC power systems.
The OT2500E40-135 provides a 4-pole configuration for high-power electrical isolation and is supplied without an operating handle and shaft. This allows the appropriate ABB operating accessories to be selected separately according to the enclosure, switchboard layout and required operating arrangement.
In its 2500 A configuration, the OT2500E40-135 uses a two-circuit arrangement and is rated DC-20B at 1500 V DC. ABB also specifies an AC-20B rating of 2500 A at 1000 V AC and, with the specified busbar support arrangement, a short-time withstand current of 80 kA for 0.3 s, providing robust performance for substantial power distribution installations.
Key Advantages
- Heavy-duty 2500 A 4-pole switch disconnector for high-current electrical isolation.

Reliable 1500 V DC High-Current Isolation
The ABB OT2500E40-135 provides a clearly defined manual isolation point for substantial DC power systems. Its DC-20B utilisation category is intended for connecting and disconnecting DC circuits under no-load conditions, making the switch suitable for maintenance and service isolation where the electrical system is designed around this utilisation category.
The combination of a 2500 A rating, 1500 V DC capability and four-pole construction makes the OT2500E40-135 particularly suitable for modern high-power DC infrastructure. ABB's specified busbar arrangement supports an 80 kA short-time withstand current for 0.3 s, while the separately selected handle and shaft provide flexibility when integrating the switch into large electrical enclosures and switchboards.
Typical Applications
- Battery energy storage systems (BESS and ESS).
- Large-scale photovoltaic power installations.
- High-power DC inverter systems.
- Industrial DC distribution switchboards.
- High-current power conversion equipment.
- 1500 V DC maintenance and service isolation systems.
