855-305/150-501 WAGO Signal Conditioners

Wago 855-305/150-501 is a plug-in measurement current transformer (CT) designed for precision in current measurement and monitoring tasks. It features CAGE-CLAMP spring connections for secure and maintenance-free wiring. The design specification of 150/5A indicates its capability to transform primary currents of up to 150 A into 5 A secondary currents. It has a rated power of 5 VA and operates without a specified supply voltage. The current transformer can function within an ambient air temperature range for operation from -5°C to +50°C and has a storage temperature range from -25°C to +70°C. It is designed for a rated insulation voltage (Ui) of 60 mm, ensuring compatibility with various installation environments. The degree of protection provided suits DIN-rail mounting (with an adapter), surface mounting, or cable mounting options. Its dimensions are H80.9mm x W60mm x D52mm, fitting into compact spaces. The type of network it is designed for is 150 A, with a measurement accuracy for 5 A currents and a maximum current classification of Class 1 (Cl.1), indicating its precision level in current measurement tasks.
