1. Product Name

Allen Bradley 188-K3D020-N 3-Pole Miniature Circuit Breaker

2. Product Introduction

The Allen Bradley 188-K3D020-N is a 3-pole Allen Bradley Miniature Circuit Breaker, rated 20A/480V AC, engineered to protect 3-phase wheat automation equipment from overloads, short circuits, and electrical faults.

3. Product Description

The Allen Bradley 188-K3D020-N is a high-performance 3-pole Allen Bradley Miniature Circuit Breaker, tailored to safeguard 3-phase electrical systems in wheat automation and industrial applications. As a key member of Allen Bradley’s circuit protection portfolio, this Allen Bradley Miniature Circuit Breaker provides robust defense for heavy-duty wheat processing equipment—such as large conveyor systems, grain drying motors, and 3-phase irrigation pumps—preventing costly downtime and equipment damage caused by electrical anomalies.

Constructed with a flame-retardant thermoplastic housing and precision-calibrated internal components, the Allen Bradley Miniature Circuit Breaker delivers exceptional durability in harsh agricultural environments. It resists dust accumulation, mechanical vibration, and temperature extremes (-25°C to 60°C) commonly encountered in grain elevators, processing plants, and outdoor wheat farm facilities. With a 20A current rating and 480V AC voltage capacity, this 3-pole Allen Bradley Miniature Circuit Breaker is perfectly sized for 3-phase wheat automation equipment, balancing protection and operational efficiency for mid-to-large power-consuming components.

The thermal-magnetic trip mechanism of this Allen Bradley Miniature Circuit Breaker offers dual-layer protection: thermal overload protection responds gradually to sustained overcurrents (e.g., overloaded conveyors), while magnetic short-circuit protection triggers instantaneously (within milliseconds) for severe faults, minimizing damage to critical wheat automation systems. It features DIN-rail mountability, enabling seamless integration into control cabinets alongside contactors, relays, and PLC modules—streamlining installation in wheat processing control setups. Compliant with global safety standards (UL 489, CE, IEC 60898), the Allen Bradley Miniature Circuit Breaker ensures compatibility with international wheat automation projects. Its compact 3-module design (135mm width) optimizes space in control panels, a valuable feature for facilities with dense electrical configurations. The manual reset function allows quick fault recovery, reducing operational disruptions in time-sensitive wheat harvesting and processing workflows.
