Product Overview
The CDM6I-160M/4300A 140A molded case circuit breaker is designed for power distribution networks, featuring thermomagnetic trip technology. With a frame current of 160A and rated current of 140A (4 poles), it offers 50kA breaking capacity to safeguard circuits against overloads and short circuits. Its fixed-mount design and front-terminal wiring simplify installation, while the robust mechanism ensures reliable performance across 220V-690V voltage ranges. Suitable for industrial automation, motor protection, and residential electrical systems. 27
Key Features
Equipped with multi-level protection functions, this breaker responds rapidly to fault currents via its thermomagnetic trip unit. The accessory-free design reduces complexity, and the manual operation handle allows direct switching control. Compatible with AC 50-60Hz systems, it supports three-phase configurations and maintains stable performance under varying loads. The compact housing saves panel space, and the isolation capability ensures safe maintenance operations. 38
Technical Specifications
Rated operational short-circuit breaking capacity (Ics) reaches 100% at 380V, with a maximum short-time withstand current (Icm) of 330kA. The modular construction withstands 25,000 mechanical operations and permits 120 operations per hour. The product’s optimized trip curve ensures precise coordination with downstream devices, while high-temperature-resistant materials extend service life in demanding environments like marine or rail transit applications. 14
Applications & Benefits
Ideal for commercial buildings, factories, and renewable energy systems, this breaker balances cost and performance. Its front-access terminals accelerate installation, and the rigid structure resists deformation under continuous use. The design accommodates fluctuating loads in solar/wind power integration, providing reliable protection against electrical faults without unnecessary interruptions. 710
