Connection Type N/A S Interrupting - Bus Bar Connection
Features N/A The traditional system used for this purpose is based on three different devices: a circuit breaker for protection against short-circuit, a thermal relay for protection against overload and phase loss or unbalance of phase, and a contactor for motor switching.
In particular, when selecting these devices, different factors must be taken into consideration, such as:
  • The motor power
  • The diagram and type of starting
  • The type of motor: with cage rotor or with wound rotor
  • The fault current at the point of the network where the motor is installed
Certifications N/A
  • UL 489 Recognized, File Number E355392 (Standard for connection terminals which allows the user to apply field wiring directly to the breaker)
  • Certified for Canada According to CSA Standards 22.2 No.5
  • IEC/EN 60947-2
  • CE Compliant
  • RoHS Compliant
