## Summary description

Busch-Jaeger 6251/8.8 is an 8-channel DIN-rail switching actuator for low-voltage DC control systems. It accepts 21–30 V DC supply, supports a maximum switching capacity of 1380 W and is powered from a DC source. Compact dimensions (144×64.5×90 mm) make it suitable for distribution cabinets and automation panels where multiple circuits require centralized switching.

## Long description

The Busch-Jaeger 6251/8.8 is an 8-channel DIN-rail switching actuator designed for low-voltage DC control installations. It operates from a DC supply voltage of 21–30 V and provides centralized switching of multiple circuits in distribution cabinets, control panels or automation racks. The device combines compact dimensions (144×64.5×90 mm) with a rated switching capacity allowing up to 1380 W total, making it suitable for managing several loads while conserving panel space.
Advantages
The actuator offers eight independent switching channels in a single DIN-rail module, reducing the number of separate relays required. Compact housing dimensions simplify integration into standard distribution cabinets and automation panels. The device is built for DC environments and supports a 21–30 V DC supply range, which ensures compatibility with common low-voltage control systems. Its rated switching capacity of 1380 W supports a range of loads while keeping wiring and installation effort minimal.
Suitable for
Switching multiple DC loads in distribution cabinets and control panels
Centralized control of lighting, pumps or small actuators in low-voltage systems
Automation racks where space-efficient multi-channel switching is required
Applications that require DIN-rail mounting and predictable DC switching performance
Key specifications
Number of channels: 8 switching channels
Supply voltage: DC 21–30 V
Maximum switching capacity: 1380 W (total)
Mounting type: DIN-rail
Dimensions (W×H×D): 144 × 64.5 × 90 mm
How to use
Mount the actuator on a standard DIN-rail inside a dry, ventilated distribution cabinet or control panel. Connect a suitable DC supply within the 21–30 V range to the supply terminals, observing correct polarity. Wire each load to the corresponding channel output according to the installation diagram and local wiring regulations. Ensure the total connected load does not exceed the rated switching capacity and verify that individual channel loads comply with system requirements before commissioning.
Usage recommendations
Use protection devices such as fuses or circuit breakers on the DC supply and load circuits to protect against overload and short circuits. Follow applicable installation standards and perform testing after installation to confirm correct switching behavior and load distribution.
