Eaton R9L3200FJ Molded Case Circuit Breaker (MCCB)

The Eaton R9L3200FJ is a high-performance molded case circuit breaker designed for demanding industrial and commercial power distribution systems. With a robust frame rated at 3200 A, it ensures reliable overcurrent protection and complies with international standards such as IEC 60947‑2. This breaker combines advanced thermal‑magnetic technology with adjustable trip settings, allowing precise coordination and selectivity in complex networks.

Key Features

• High Breaking Capacity: Suitable for installations with high prospective short‑circuit currents.

• Adjustable Thermal‑Magnetic Trip: Independently adjustable overload (thermal) and short‑circuit (magnetic) protections.

• Robust Construction: Reinforced frame and arc‑chambers for extended electrical life.

• Compact Design: Optimized dimensions for space‑saving panel integration.

• Accessory Compatibility: Accepts auxiliary contacts, shunt trips, undervoltage releases, and motor operators.

Technical Specifications

Operational Benefits

The thermal‑magnetic trip unit of the R9L3200FJ provides time‑delayed overload protection (thermal) and instantaneous magnetic protection against short circuits. The thermal element is ambient temperature compensating, ensuring consistent performance across varying conditions. The magnetic trip threshold can be adjusted to match specific load characteristics, reducing nuisance tripping while maintaining safety.

Typical Applications

• Main switchboards in industrial plants

• Power distribution in commercial buildings

• Protection of large motors, transformers, and capacitors

• Generator and UPS output protection

• Retrofit and upgrade of existing distribution panels

Accessories and Customization

The R9L3200FJ supports a wide range of internal and external accessories, including auxiliary switches, alarm contacts, shunt trip releases, undervoltage releases, and rotary handle operators. These accessories enable remote monitoring, automatic shutdown, and enhanced operator safety. The breaker can also be integrated into energy management systems via communication modules (Modbus, Profibus).

With its proven design and Eaton’s commitment to quality, the R9L3200FJ ensures continuity of service and protection of valuable assets in critical power applications.
