MCCB 1250A, YCM7RT (Adjustable) 50/50kA refers to a heavy-duty molded case circuit breaker in the CNC Electric YCM7RT series.

Specifications:

• Type: Molded Case Circuit Breaker (MCCB)
• Series: YCM7RT (Thermal-Magnetic Adjustable)
• Rated Current (In): 1250 A
• Trip Unit: Adjustable overload and short-circuit settings
• Breaking Capacity:
  • Icu (Ultimate Breaking Capacity): 50 kA
  • Ics (Service Breaking Capacity): 50 kA
• Poles: Available in 3P and 4P versions
• Applications: Main incomer, feeder protection, generator and transformer protection, and industrial distribution panels.

Meaning of 50/50kA:
The breaker can interrupt fault currents up to 50,000 A, and its service breaking capacity is also 50,000 A, meaning it can continue operating at its full rated fault level after interruption.
