Supplementary isolating device for remote operation of a circuit breaker for electrical equipment

An electrical system for a motor, comprising:

• an electrical drive system configured to drive the motor,
• a circuit breaker with interlocking functionality,
• wherein the circuit breaker is configured to disconnect the electrical drive system from a power source configured to power the electrical drive system, and
• a supplementary isolating device configured to operate the circuit breaker from a remote location relative to the circuit breaker and the electrical drive system including:
• an electrical disconnection switch manoeuvrable between a mechanically lockable first position and a mechanically lockable second position, which electrical disconnection switch is configured to be connected in the control circuit of a circuit breaker for an electrical drive system,
• wherein the supplementary isolating device is configured to send a first control voltage to the circuit breaker to provide an electrical disconnect and interlocking the operation of the circuit breaker, when the electrical disconnection switch is in the first position,
• an electric terminal configured to be connected to an auxiliary contact of the circuit breaker to obtain an operational status of the circuit breaker, and
• an indicator configured to indicate the operational status of the circuit breaker.
