1. Product Name

Allen Bradley 20JEF3F3K6LNDNNNNN-C1-P16 3-Pole C-Curve Miniature Circuit Breaker (MCB)

2. Product Introduction

The Allen Bradley 20JEF3F3K6LNDNNNNN-C1-P16 is a 3-pole (3P) C-curve Miniature Circuit Breaker rated at 6A, offering thermal-magnetic protection for three-phase industrial circuits against overloads and short circuits.

3. Product Description

The Allen Bradley 20JEF3F3K6LNDNNNNN-C1-P16 is a high-performance Miniature Circuit Breaker, part of Allen Bradley’s trusted 20JEF series engineered for precise three-phase circuit protection in industrial automation. As a premium Allen Bradley Miniature Circuit Breaker, it serves as a critical safety component, shielding three-phase equipment, wiring, and personnel from electrical faults that could cause downtime, equipment damage, or safety hazards.

Constructed with flame-retardant UL94 V0 thermoplastic housing and precision-engineered internal components, this Allen Bradley Miniature Circuit Breaker delivers exceptional durability in harsh industrial environments—resisting vibration, extreme temperatures (-25°C to 70°C), and chemical exposure common in manufacturing, agricultural processing, and logistics. Its core thermal-magnetic tripping mechanism, optimized with a C-curve (5–10x rated current) response, provides tailored protection: the thermal element offers inverse-time overload protection to handle sustained excess current, while the magnetic element delivers instantaneous tripping for rapid short-circuit mitigation—ideal for general industrial loads like motors and pumps.

With a 3-pole (3P) configuration and 6A rated current, the 20JEF3F3K6LNDNNNNN-C1-P16 is optimized for low-to-medium current three-phase circuits, such as those powering small three-phase motors, grain conveyor drives, irrigation pump systems, and three-phase control panels. It supports a maximum voltage rating of 480V AC, compatible with standard industrial three-phase power systems, and features a compact design (180×90×75mm) that fits standard 35mm DIN rail mounting—enabling seamless integration into control cabinets alongside other Allen Bradley automation components.

This Allen Bradley Miniature Circuit Breaker complies with global safety standards including UL 489, IEC 60898-1, and CE, ensuring compliance in international markets. It boasts a 10kA breaking capacity at 480V AC, providing reliable protection even in high-fault-current scenarios. The breaker includes a manual reset lever with clear on/off visual indicators, allowing operators to quickly identify circuit status and restore power post-tripping. It also integrates advanced arc-quenching technology to suppress electrical arcing during tripping, reducing fire risks and extending component lifespan.

Designed to integrate seamlessly with Allen Bradley’s automation ecosystem, the 20JEF3F3K6LNDNNNNN-C1-P16 works in harmony with ControlLogix PLCs, PowerFlex VFDs, and PanelView HMIs—forming a comprehensive three-phase control and protection system. It supports selective coordination with other protective devices, ensuring only the faulty circuit is isolated to minimize operational downtime. The breaker’s low power dissipation and high mechanical endurance (10,000 on/off cycles) enhance long-term reliability and cost-effectiveness, making it a preferred choice for critical three-phase industrial applications.
