Key Features Circuit Breaker Type: 3‑pole fixed molded case circuit breaker (MCCB). Trip Unit: Thermomagnetic (TMF) release — offers overload and short‑circuit protection in one unit. Terminal Type: Front terminals for easy connection in panel or distribution board installations. Compact Design: Space‑efficient profile suitable for modular panel layouts. Durability: Engineered for frequent switching and fault interruption cycles. Electrical Ratings Rated Current (In): 125 A — continuous load capacity. Rated Operational Voltage: Suitable for AC systems up to ~550 V AC and DC up to ~250 V DC. Rated Insulation Voltage (Ui): ~690 V. Impulse Withstand Voltage (Uimp): ~6 kV. Rated Ultimate Short‑Circuit Breaking Capacity (Icu): High breaking capacity appropriate for industrial power distribution levels. Service Short‑Circuit Breaking Capacity (Ics): Substantial portion of Icu to provide dependable service interruption performance. Operating Frequency: Designed for standard industrial power frequencies (50/60 Hz). Tripping Mechanism: Thermal element: Protects against sustained overloads. Magnetic element: Instantaneous protection against high short‑circuit currents. Mechanical & Environmental Number of Poles: 3 poles — simultaneous protection of all three phases in three‑phase systems. Electrical Durability: Rated for multiple make/break cycles throughout service life. Mechanical Durability: Built for a high number of mechanical operations. Operating Temperature Range: Suitable for typical industrial ambient conditions. Enclosure Protection: Intended for installation inside electrical panels or enclosed distribution boards with appropriate protection ratings. Physical & Installation Mounting: Panel or enclosure installation, front‑accessible connections. Terminals: Front‑tie connections for convenient wiring. Dimensions: Compact footprint that fits standard industrial panel layouts. Weight: Designed to balance robustness with manageable physical size. Typical Applications Branch‑circuit protection in industrial and commercial power distribution. Protection of motor feeders, transformers, and distribution circuits in machinery and plant installations. Main or sub‑panel protection where a reliable breaker with thermomagnetic trip characteristics is required. Load isolation and system safety in electrical switchboards and control cabinets.
