2. Product Introduction

The Allen Bradley 20GEG4C1K2MNANNNNN-C0 is a 600V-rated C-curve Miniature Circuit Breaker equipped with a C0 accessory, delivering precise overload/short-circuit protection for industrial electrical systems.

3. Product Description

The Allen Bradley 20GEG4C1K2MNANNNNN-C0 is a high-performance Miniature Circuit Breaker from Allen Bradley’s 20GE series, engineered for 600V AC industrial applications requiring reliable C-curve protection and integrated accessory functionality. As a critical component of industrial electrical infrastructure, this Allen Bradley Miniature Circuit Breaker combines thermal-magnetic tripping technology with rugged construction, safeguarding equipment and personnel from electrical hazards in demanding operational environments.

Crafted with flame-retardant glass-fiber-reinforced polyester housing and silver-alloy contacts, the Allen Bradley Miniature Circuit Breaker exhibits exceptional voltage resistance and arc quenching capabilities. Its C-curve tripping characteristic is optimized for protecting circuits with moderate inrush currents—ideal for motor-driven equipment, lighting systems, and power distribution lines. The thermal element provides delayed tripping for sustained overloads (e.g., extended motor operation), while the magnetic element delivers instantaneous tripping for short circuits with a breaking capacity of up to 15kA, minimizing equipment damage and downtime. The integrated C0 accessory (a standard auxiliary contact module) enables real-time circuit status monitoring (ON/OFF/tripped), enhancing operational visibility and control.

Rated for 600V AC 3-phase operation, this Allen Bradley Miniature Circuit Breaker complies with global safety standards including UL 489, IEC 60898, and CE, ensuring compatibility with international electrical systems. The compact design (9.0×11.3×22.0cm) facilitates space-efficient installation in distribution boards and control cabinets, while the ergonomic toggle switch features clear visual indicators for intuitive operation and quick fault identification. It supports tool-less DIN-rail mounting and heavy-duty clamping terminals, simplifying installation and maintenance.

The “G4C” configuration denotes enhanced 600V performance and C-curve tripping optimization, while the 1K2 rating indicates a 1.2A current capacity—tailored for low-to-medium load circuits. This Allen Bradley Miniature Circuit Breaker operates reliably in temperatures ranging from -25°C to 70°C and holds an IP20 rating, shielding internal components from dust and debris in industrial settings. It features a lockable toggle switch to prevent unauthorized resets, reinforcing operational safety. Seamlessly compatible with Allen Bradley’s automation ecosystem (including ControlLogix PLCs and PowerFlex VFDs), it integrates into unified protection networks for centralized control.

Designed for selective coordination, the breaker ensures only faulty circuits are isolated, minimizing operational disruption. The C0 accessory’s status monitoring capability supports predictive maintenance strategies, enabling early detection of electrical anomalies. This Allen Bradley Miniature Circuit Breaker is ideal for 600V industrial networks, including manufacturing plants, agricultural processing facilities, and logistics hubs, where precise C-curve protection and status visibility are critical.
