FJG/UKK Series DIN Rail Power Distribution Terminal Block
Product Features
- DIN rail-mounted power distribution terminal block.
- One-input, multiple-output configuration for efficient power distribution.
- Screw clamping connection ensures stable mechanical strength and low contact resistance.
- Compact structure suitable for high-density wiring arrangements.
- Supports phase, neutral, protective earth, and equipotential conductor distribution.
- Suitable for modular system design and circuit expansion.
Detailed introduction
Application
The FJG/UKK series DIN rail power distribution terminal blocks are designed for centralized power distribution and circuit branching in low-voltage electrical systems.
They are widely used in control cabinets, switchgear assemblies, power distribution panels, and multi-circuit enclosures for distributing power from one incoming conductor to multiple outgoing circuits.
This series provides a compact and reliable alternative to small busbars for phase, neutral, protective earth, and equipotential conductor distribution.
