AC Circuit Breaker MCCB Type AC-MCCB-630 (Order Basis)

👉 AC (Alternating Current): Operates on AC systems, typically up to 415V or 690V.

👉 MCCB (Molded Case Circuit Breaker): A robust breaker for high currents, with a molded plastic case.

👉 630: Indicates the rated current (In) or frame size, meaning it's designed for circuits carrying up to 630 Amps.

Common Features & Variations:

👉 Poles: Available in 3-pole (3P) or 4-pole (4P) configurations for three-phase systems.

👉 Mounting: Often fixed-mounted for permanent installation.

👉 Breaking Capacity (Icu/Ics): Varies by model (e.g., 36kA, 50kA, 70kA), indicating the maximum fault current it can interrupt safely.

👉 Trip Unit: Can be thermal-magnetic (adjustable settings) or electronic (offering more precise settings like L, S, I – Long Time, Short Time, Instantaneous).

👉 Standards: Conforms to international standards like IEC 60947-2.

Typical Applications:

👉 Protection for transformers, generators, and main distribution panels.

👉  Circuit protection in low voltage distribution systems.
