• Test socket on both sides of the disconnect point enables safe, clear testing in current transformer secondary circuits
• Test sockets can bridge across to neighboring terminal blocks for expanded circuit verification
• Wide conductor acceptance - rigid 0.5 mm² to 16 mm² (AWG 20-6) and flexible 0.5 mm² to 10 mm² - supports diverse wiring configurations
• Fire protection per DIN EN 45545-2 (R22, R23, R24, R26 HL 1-HL 3) qualifies the block for rail vehicle installations

Applications:

• Current transformer secondary circuit testing in protection relay panels
• Metering and measurement switchboards requiring accessible, isolated test points
• Railway and transportation electrical enclosures (DIN EN 45545-2 compliant)
• Industrial control cabinets with high-density DIN rail terminal layouts

Compliant with IEC 60947-7-1. Part of the Phoenix Contact URTK/S test disconnect terminal block series.
