What is d5 11 50g in abb circuit breaker wiring circuit

A very specific question!

In an ABB circuit breaker wiring circuit, D5 11 50G is a designation that refers to a specific configuration or setting for the circuit breaker.

Here's a breakdown of what each part of the designation likely means:

• D5: This is the type of circuit breaker. In ABB's terminology, D stands for "drawout" (i.e., the breaker can be withdrawn from the panel for maintenance or replacement), and 5 is the specific type of breaker (e.g., a 5-pole breaker).
• 11: This is the number of poles (or phases) of the circuit breaker. In this case, it's a 3-phase breaker with 11 poles (i.e., 3 phases and a neutral).
• 50G: This is the rating of the circuit breaker in amperes (A) and gigawatts (G). In this case, the breaker is rated for 50 amperes and 0.05 gigawatts (50,000 amps).

So, in summary, D5 11 50G is a 3-phase, 11-pole, 50A, 0.05G circuit breaker that can be withdrawn from the panel for maintenance or replacement.
