1. Product Name

Allen Bradley 20GE6NC037LNANNNNN-C0 Miniature Circuit Breaker (MCB)

2. Product Introduction

The Allen Bradley 20GE6NC037LNANNNNN-C0 is a high-performance Miniature Circuit Breaker, engineered for industrial electrical systems to provide reliable overload, short-circuit, and fault protection.

3. Product Description

The Allen Bradley 20GE6NC037LNANNNNN-C0 is a premium Miniature Circuit Breaker from Allen Bradley’s 20GE series, designed to safeguard industrial electrical circuits, equipment, and personnel from electrical hazards. As a core component of industrial safety infrastructure, this Allen Bradley Miniature Circuit Breaker integrates advanced protection mechanisms with rugged construction, making it ideal for demanding automation environments.

Crafted with industrial-grade thermoplastic housing and silver-alloy contacts, the Allen Bradley Miniature Circuit Breaker delivers exceptional durability and arc-quenching performance. It features a thermal-magnetic tripping mechanism: the thermal component responds to sustained overloads (adjustable via current rating) by opening the circuit gradually, while the magnetic component provides instantaneous tripping (up to 10kA breaking capacity) to interrupt short circuits within milliseconds. This dual-action design ensures precise, reliable protection against both gradual overloads and sudden electrical faults, preventing equipment damage and fire risks.

Rated for 37A current, 480V AC 3-phase applications, this Allen Bradley Miniature Circuit Breaker is compatible with a wide range of industrial systems—from motor control panels to automation cabinets. It meets global safety standards including UL 489, IEC 60898, and CE, ensuring compliance with international electrical codes. The compact design (6.5×9.0×18.5cm) allows for 密集 installation in control panels, optimizing space utilization, while the ergonomic toggle switch enables easy manual operation and status visibility (ON/OFF/tripped).

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

Equipped with a trip indicator and lockable toggle switch, the Allen Bradley Miniature Circuit Breaker enhances operational safety by preventing unauthorized resetting and providing clear visual status. It also supports selective coordination with other protective devices, ensuring that only the affected circuit is isolated during a fault, minimizing system-wide downtime.
