WAGO 855-501/150-000 Current and Voltage Measurement Tap, 0.5-50 mm², 150 A, Gray

The WAGO 855-501/150-000 is a compact current and voltage measurement tap designed for DIN-rail mounting. It enables non-invasive current measurement via an integrated current transformer and direct voltage tapping, making it ideal for energy monitoring and control applications. With a maximum conductor cross-section of 50 mm² and rated current of 150 A, it is suitable for industrial and building automation systems.

Advantages

Non-invasive current measurement eliminates the need to break the main conductor. CAGE CLAMP® connection technology ensures fast, reliable, and maintenance-free wiring. Compact design saves space on the DIN-rail. Wide operating temperature range from -35 to +85 °C ensures reliable performance in harsh environments.

Suitable for

• Energy monitoring and sub-metering in industrial plants
• Building automation and smart grid applications
• Integration into power distribution panels and switchgear
