1. Product Name

Allen Bradley 20GE7NC140LNANNNNN-C0 140A Miniature Circuit Breaker (MCB)

2. Product Introduction

The Allen Bradley 20GE7NC140LNANNNNN-C0 is a high-current Miniature Circuit Breaker, engineered to protect heavy-duty industrial electrical systems from overloads, short circuits, and electrical faults.

3. Product Description

The Allen Bradley 20GE7NC140LNANNNNN-C0 is a premium high-current Miniature Circuit Breaker from Allen Bradley’s 20GE series, tailored for demanding industrial environments requiring robust protection for large electrical loads. As a critical component of industrial safety infrastructure, this Allen Bradley Miniature Circuit Breaker integrates advanced thermal-magnetic tripping technology with rugged construction, ensuring reliable performance in high-power applications.

Crafted with reinforced industrial-grade thermoplastic housing and silver-nickel alloy contacts, the Allen Bradley Miniature Circuit Breaker delivers exceptional durability, arc-quenching efficiency, and resistance to electrical wear. Its dual-action tripping mechanism combines thermal overload protection (for sustained current surges) and magnetic short-circuit protection (for instantaneous fault interruption up to 10kA breaking capacity). This precise coordination ensures rapid response to both gradual overloads and sudden electrical faults, preventing equipment damage, downtime, and fire hazards in high-current systems.

Rated for 140A current and 480V AC 3-phase operation, this Allen Bradley Miniature Circuit Breaker is optimized for heavy-duty industrial equipment—including large motors, high-power conveyors, and industrial automation systems. It meets global safety certifications such as UL 489, IEC 60898, and CE, ensuring compliance with international electrical codes for global deployment. The compact design (7.5×9.0×18.5cm) facilitates space-efficient installation in control panels, while the ergonomic toggle switch provides clear ON/OFF/tripped status visibility and easy manual operation.

A key strength of this Allen Bradley Miniature Circuit Breaker is its seamless integration with Allen Bradley’s industrial automation ecosystem, including PowerFlex VFDs, ControlLogix PLCs, and motor starters, creating a unified safety network. It features pluggable terminals for quick wiring and replacement, minimizing maintenance downtime. The breaker operates reliably in temperatures ranging from -25°C to 70°C, tolerating extreme fluctuations in industrial facilities, and its IP20 dust-resistant rating protects internal components from contaminants.

Equipped with a lockable toggle switch and trip indicator, the Allen Bradley Miniature Circuit Breaker enhances operational safety by preventing unauthorized resetting and providing immediate visual feedback of fault conditions. It also supports selective coordination with other protective devices, ensuring only the affected circuit is isolated during a fault—maximizing system uptime for critical industrial operations.
