Allen Bradley 20GED3F330MNDNNNNN-C0-C12 330A Miniature Circuit Breaker (MCB)

2. Product Introduction

The Allen Bradley 20GED3F330MNDNNNNN-C0-C12 is a high-capacity Miniature Circuit Breaker, engineered to safeguard ultra-heavy-duty industrial electrical systems from overloads, short circuits, and critical faults.

3. Product Description

The Allen Bradley 20GED3F330MNDNNNNN-C0-C12 is a top-tier high-current Miniature Circuit Breaker from Allen Bradley’s 20GE series, designed for extreme industrial environments where massive electrical loads demand uncompromising protection. As a cornerstone of industrial electrical safety, this Allen Bradley Miniature Circuit Breaker merges advanced thermal-magnetic tripping technology with ruggedized construction, delivering reliable performance for 330A high-power applications.

Constructed with reinforced glass-fiber-reinforced polyester housing and silver-alloy contacts, the Allen Bradley Miniature Circuit Breaker offers exceptional mechanical strength, arc-quenching efficiency, and resistance to electrical degradation. Its dual-action tripping mechanism provides precise protection: thermal overload protection responds to sustained current surges (e.g., motor startup spikes), while magnetic short-circuit protection instantly interrupts faults up to 15kA breaking capacity—preventing equipment meltdown, production downtime, and fire hazards in high-current systems.

Rated for 330A current and 480V AC 3-phase operation, this Allen Bradley Miniature Circuit Breaker is optimized for ultra-heavy-duty industrial equipment, including large industrial motors, high-power conveyor networks, and massive automation systems. It complies with global safety certifications such as UL 489, IEC 60898, and CE, ensuring adherence to international electrical codes for worldwide deployment. The compact footprint (8.2×9.5×19.0cm) enables space-efficient installation in control panels, while the ergonomic toggle switch provides clear ON/OFF/tripped status visibility and effortless manual operation.

A key advantage 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 control centers (MCCs), forming a unified safety network. It features pluggable, screw-clamp 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 shields internal components from contaminants.

Equipped with a lockable toggle switch and LED trip indicator, the Allen Bradley Miniature Circuit Breaker enhances operational safety by preventing unauthorized resetting and providing immediate visual fault feedback. It supports selective coordination with other protective devices, ensuring only the affected circuit is isolated during a fault—maximizing uptime for critical industrial operations. The dual-configuration identifier (C0-C12) denotes compatible accessory integration, allowing customization with shunt trips or auxiliary contacts for enhanced system control.
