Features and benefits:

• Knife-disconnect function separates circuits without removing conductors, simplifying maintenance
• Maintenance-free and vibration-resistant construction using the patented Reakdyn principle
• Accepts two identical conductors per terminal for space-efficient and flexible wiring
• Integrated level bridging connects circuits across terminal levels in minimal footprint
• Low self-heating due to high contact forces and high-quality insulating materials

Applications:

• Circuit isolation and in-service test-plug access in industrial switchgear and control panels
• Railway rolling stock wiring requiring DIN EN 45545-2 fire protection compliance
• Machine building and plant engineering signal and power distribution
• Commissioning and fault-finding tasks requiring live measurement without disconnection

Compliant with IEC 60947-7-1, UL 94 V0 flammability, DIN EN 45545-2 (R22/R23/R24/R26, HL 1 - HL 3), and NFPA 130. Part of the Phoenix Contact UT terminal block family.
