Reversing systems enable for using of electrical motors in two rotary directions and also they are suitable for Automatic Transfer switch Systems (network-network).
Reversing systems consist of the following elements:
- two 3-poles contactors with the similar dimensions from series CRNI09...CRNI38 (4...18,5 kW), where two phases are changed,
- additional auxiliary contacts CRI20-10 (1N/O),
- mechanical latches CRI-410,- set of connection wires designed for reversing systems - bottom and top connection 3RA 1923-2A or 3RA 1933,
Reversing systems enable easy, fast and dependable wire connection.
Starting characteristics are suitable to characteristics of directly starters.
Applications with the adequate safety devices reversing systems are very advantageous to save compact space of branching with fuses or without fuses.
