ABB 1SDA069823R1 T4D/PV 250 4-Pole 1100 V DC Switch-Disconnector

The ABB 1SDA069823R1 is a Tmax T4D/PV 250 switch-disconnector designed for reliable isolation and switching in photovoltaic and high-voltage DC electrical installations. This fixed four-pole device is rated for up to 250 A and 1100 V DC.

Featuring front terminals and a compact moulded-case construction, the T4D/PV 250 provides a practical solution for DC circuit isolation where dependable operation and clearly defined switching performance are required. The device is manufactured to IEC 60947 standards and has an IP20 degree of protection.

ABB 1SDA069823R1 is particularly suited to photovoltaic power distribution, DC combiner systems and other high-voltage DC applications where four-pole switching and isolation are required.

Key Advantages

  • Designed for photovoltaic and high-voltage DC applications up to 1100 V DC
  • 250 A rated uninterrupted current for substantial DC power distribution requirements
  • Four-pole configuration for comprehensive DC circuit isolation
  • Fixed construction with front terminals for straightforward installation
  • Compact Tmax moulded-case design for industrial switchgear assemblies
  • Manufactured to IEC 60947 requirements
  • IP20 enclosure protection for installation within suitable electrical equipment

Key Features

  • Manufacturer: ABB
  • Part number: 1SDA069823R1
  • Product family: Tmax
  • Type: T4D/PV 250
  • Device function: switch-disconnector
  • Four-pole configuration

Photovoltaic and High-Voltage DC Switching

The ABB T4D/PV 250 is engineered specifically for DC switching and isolation within photovoltaic electrical systems. Its 1100 V DC rating makes it suitable for high-voltage PV architectures where conventional low-voltage AC switchgear is not appropriate.

The four-pole configuration allows the device to provide comprehensive isolation within DC distribution arrangements, while the fixed front-terminal construction supports integration into switchboards, combiner equipment and other electrical assemblies.

Typical Applications

  • Photovoltaic power distribution systems
  • Solar PV combiner and distribution equipment
  • High-voltage DC switchboards
  • DC isolation and switching systems
  • Solar inverter and DC-side protection assemblies
  • Industrial DC power distribution
  • Renewable-energy electrical installations
