Key Features Type: 3‑pole molded case circuit breaker (fixed, non‑adjustable). Release Mechanism: Thermal‑magnetic (TMF) trip unit, combining thermal overload protection with instantaneous magnetic short‑circuit tripping. Front Terminals: Designed for easy connection and installation from the front of the breaker. Compact Design: Space‑saving dimensions suitable for control panels, distribution boards, or equipment protection. Electrical Ratings Rated Current (In): 250 A — nominal continuous current capacity of the main circuit. Control/Operational Voltages: Rated to interrupt under AC low‑voltage network conditions (AC) and DC loads as part of comprehensive protection. Insulation & Withstand: Designed for 690 V rated insulation and high impulse withstand voltage levels. Short‑Circuit Performance: Ultimate breaking capacity (Icu): High rated short‑circuit breaking performance suitable for industrial systems. Service short‑circuit breaking capacity (Ics): Substantial fraction of Icu, allowing effective protection and service continuity. Mechanical & Environmental Poles: 3 (three‑phase) — simultaneous protection of all three lines in a 3‑phase system. Mechanical Durability: Constructed to endure repeated manual switching and fault events. Operating Environment: Suitable for typical electrical cabinet environments in industrial and commercial installations. Physical & Installation Mounting: Panel or equipment mounting using fast clip/DIN rail or panel interface as designed for MCCBs. Terminals: Front access screw/clamp terminals provide secure connection for incoming and outgoing conductors. Compact Footprint: Reduced width profile compared to larger breaker frames, conserving panel space. Typical Applications Main and branch‑circuit protection in industrial and commercial power distribution. Motor feeder and equipment protection where short‑circuit and overload interruption are required. Control panels and switchgear needing compact, reliable circuit protection. Protection of generators, transformers, and distribution circuits in low‑voltage systems.
