WAGO 855-951/250-000 Current and Voltage Tap up to 95 mm²

The WAGO 855-951/250-000 is a high-quality current and voltage tap designed for energy measurement and power monitoring applications. It accommodates main conductors from 10 mm² to 95 mm² (AWG 8 to 3/0) and features CAGE CLAMP® connection technology for secure and maintenance-free wiring. The measurement circuit uses Push-in CAGE CLAMP® for conductors from 0.2 mm² to 2.5 mm² (AWG 24 to 14). Rated for 1000 V and 250 A, this tap is suitable for industrial environments with pollution degree 3 and overvoltage category III. The housing is made of polyamide 66 with UL 94 V-0 flammability rating, and the operating temperature range is -35 °C to +85 °C. It can be mounted on a DIN rail using adapter 209-188 or via screw mounting.

Advantages

Reliable CAGE CLAMP® connection ensures vibration-proof and corrosion-resistant contacts. Compact design saves space in control cabinets. High current and voltage ratings allow use in demanding power distribution systems. Easy installation with push-in technology for measurement wires.
