Product Introduction

The Pole Mounted Circuit Breaker D265T (Middle Pole) with Digital Trip Unit is a specialized low-voltage (LV) protection component designed for pole-mounted electrical configurations. As a "middle pole" variant, it fits into multi-pole power distribution systems (e.g., 3-pole setups) to manage and protect the middle phase circuit, while the integrated digital trip unit elevates its fault-sensing precision. It is widely used in industrial power distribution networks, commercial building electrical systems, and infrastructure power grids, where it safeguards circuits, transformers, and connected equipment from overloads, short circuits, and other electrical faults.

Features

• Targeted Middle Pole Protection：Tailored as a middle pole unit for multi-pole (e.g., 3-pole) systems, it ensures balanced current management and fault isolation for the middle phase—critical for maintaining stable 3-phase power supply and preventing phase imbalance-related damage.

• Digital Trip Unit for Precision：Equipped with a digital trip unit that enables accurate fault detection (overload, short circuit) and adjustable trip settings. Unlike analog units, it reduces false trips, supports real-time current monitoring, and allows customization to match specific load requirements.

• Pole-Mounted Design for Space Efficiency：Optimized for pole-mounted installation, it saves space in switchgear cabinets or outdoor power enclosures. The design simplifies integration into existing pole-based distribution setups, reducing installation complexity and saving layout space.

• Rapid Fault Response：The digital trip unit enables fast trip action (typically milliseconds) when faults occur, minimizing the duration of abnormal current flow. This protects sensitive equipment (e.g., motors, controllers) from thermal or electrical damage caused by prolonged faults.

• Durable & Reliable Operation：Built with robust materials resistant to electrical arcing and environmental factors (e.g., dust, mild moisture), it maintains stable performance in industrial/commercial environments. The pole-mounted structure also enhances mechanical stability during long-term use.
