1. Product Name

Allen Bradley 2100R-HOA400 400A Molded Case Circuit Breaker (MCCB)

2. Product Introduction

The Allen Bradley 2100R-HOA400 is a 400A molded case circuit breaker (MCCB) engineered for heavy-duty industrial power protection, delivering reliable overcurrent and short-circuit safeguarding for high-current distribution systems and critical equipment.

3. Product Description

The Allen Bradley 2100R-HOA400 stands as a high-performance Molded Case Circuit Breaker, designed to meet the rigorous demands of industrial power distribution and equipment protection. As a flagship offering in Allen Bradley’s 2100R series, this MCCB builds on the brand’s legacy of reliability, complementing the precision of Allen Bradley Miniature Circuit Breakers with robust protection for high-current applications. It serves as a critical defensive layer for industrial main distribution panels, motor control centers, and heavy machinery, shielding against overloads, short circuits, and ground faults that could lead to costly downtime or equipment damage.

Crafted with a rugged metallic housing and high-grade conductive components, the 2100R-HOA400 excels in harsh industrial environments. It operates reliably within a temperature range of -20°C to 70°C, resists mechanical impact and chemical corrosion, and maintains performance in dusty, humid, or vibration-prone settings—ideal for manufacturing plants, oil & gas facilities, and large-scale industrial complexes. At its core, the thermal-magnetic tripping mechanism offers adjustable overload protection (long-time delay) and instantaneous short-circuit tripping, with a breaking capacity of up to 65kA at 480V AC—ensuring rapid fault clearance even in high-fault-current scenarios.

With a 400A rated current and 3-pole configuration, the 2100R-HOA400 is optimized for three-phase industrial power systems, including main power distribution lines, large motor circuits, and heavy-duty equipment feeds. It supports a maximum voltage rating of 600V AC (three-phase) and 250V DC, compatible with standard industrial power grids, and features a compact footprint that balances robust construction with space efficiency—facilitating integration into existing distribution boards and control rooms.

This Allen Bradley MCCB adheres to global safety standards such as UL 489, IEC 60947-2, and CE, ensuring compliance across international markets. It integrates advanced arc-quenching technology to suppress electrical arcing during tripping, minimizing fire risks and extending the breaker’s service life. The unit includes a manual operating handle with clear on/off indicators, enabling quick status identification, and supports optional accessories such as shunt trips, undervoltage releases, and auxiliary contacts for enhanced control and monitoring capabilities.

Designed to seamlessly integrate with Allen Bradley’s automation ecosystem, the 2100R-HOA400 works in harmony with ControlLogix PLCs, FactoryTalk software, and PowerFlex VFDs—creating a unified power protection and control system. It supports selective coordination with other protective devices, ensuring only the faulty circuit is isolated to maintain operational continuity. The breaker’s high mechanical endurance (5,000 on/off cycles) and low power dissipation enhance long-term reliability, while its easy-to-install design (bolt-on mounting) simplifies maintenance and replacement. Whether safeguarding critical production lines or large-scale power distribution networks, the 2100R-HOA400 delivers the rugged performance and precision expected from Allen Bradley’s circuit protection lineup.
