Description
Differential current circuit breaker without built-in overcurrent protection type VD3-63 of KARAT series is designed for automatic power off in case of insulation fault in single-phase and three-phase AC electric circuits with rated voltage up to 400 V and frequency 50 Hz. Switches are electromechanical type and functionally independent from line voltage and designed for use in residential, public and industrial buildings, on construction sites and are installed in low-voltage complete input and output devices, with degree of protection not less than IP30. The VDT is not designed to disconnect short-circuit currents and overcurrents.
Life time:
15 years
Warranty:
10 years
Advantages
- Electromechanical circuit without electronic components.
- Tightening torque of the terminal screw with a screwdriver is 4 N-m.
- Short circuit rated current 6 kA.
- Independent contact position indicator.
- Wide temperature range from -25°C to +45°C.
- Has no own power consumption and maintains operability in case of breakage of neutral conductor.
- Notches on the contact terminals reduce heat losses and increase mechanical stability of the connection.
