855-301/100-201 WAGO Signal Conditioners

Wago 855-301/100-201 is a plug-in measurement current transformer (CT) designed for precision in current measurement within electrical systems. It features CAGE-CLAMP spring connections for secure and maintenance-free wiring. The design specification is 100/1A, indicating its capability to transform 100 A of primary current down to 1 A of secondary current. It has a rated power of 2.5 VA and operates without a specified supply voltage. The transformer can function within an ambient air temperature range for operation from -5°C to +50°C and for storage from -25°C to +70°C. It is designed for use in environments requiring a degree of protection classified as Class 1 (Cl.1) for measurement accuracy. The rated insulation voltage (Ui) stands at 60 mm. This current transformer supports a variety of installation methods including DIN-rail (with adapter), surface, and cable, making it versatile for different setups. The dimensions are H80.9mm x W60mm x D52mm, suitable for compact spaces. It is designed for networks with a type of 100 A and ensures a measurement accuracy within 1 A maximum current.
