Residual Current Monitor device Type B. Associated to external core balance transformer the CTB-1/xxx family. It has 2 programmables outputs relays. Main trip and prealarm signal. It has one free voltage input for external TRIP/RESET. Mounting in DIN rail 466277 or PANEL 72x72 by means of accesories (3EDA03). Displays setting values and instantaneus earth leakage current value.

Field of Application

Type B relays are widely used where they can generate, in case of failure, continuous discharge currents; Common application fields are:

• Frequency converters
• Medical devices such as radiography and / or TAC equipment
• Inverters for photovoltaic systems (side c.a.)
• Power supply lifts
• Test facilities in laboratories
• Means of production in the yards
• Loading stations and forklift trucks
• Cranes for industry, crafts and trade
• Mechanical workshops, for example for arc welding machines
• Metalworking machines for numerical control
