Product Definition
The SUT-6S test disconnect terminal block enables live-circuit testing and maintenance in 1000V industrial control systems. Supporting 0.2–10 mm² conductors at 41A continuous current, it allows operators to safely isolate circuits without power interruption. Compatible with FBS jumpers and ZB8 marking systems, it streamlines diagnostics in automation, power distribution, and instrumentation applications.

Core Innovations
1. Safe Live-Circuit Testing
- Isolated test sockets: Ø4mm probe ports with finger-safe shutters (IP20 protection)
- Visual disconnect status: Red/green indicator shows circuit isolation state
2. Top-Access Bridging
- FBS jumper compatibility: Vertical top-down insertion for space-efficient wiring
- Multi-directional contacts: Supports 90° angled jumper configurations
3. Rotary Disconnect Mechanism
- Tool-free operation: 90° rotary switch isolates circuits in <1 second
- Maintained connection: Input/output terminals remain bridged during testing
4. Maintenance Optimization
- Integrated test points: Measure voltage/current without disconnecting wires
- ZB8 marking strip ready: 8.0mm laser-engravable labels for circuit identification
