2 Pole AC Circuit Breaker For Low Voltage Distribution

Pugao supplies 2 Pole AC Circuit Breaker For Low Voltage Distribution for low-voltage AC power systems requiring reliable dual-pole isolation and circuit protection. Manufactured by Zhejiang Pugao Electric Power Co., Ltd. (Plannter Electric), the breaker features flame-retardant housing materials, high-temperature resistant copper components, and a standard 35mm DIN rail mounting design.

Applications

PUGAO’s 2 Pole AC Circuit Breaker For Low Voltage Distribution is designed for single-phase electrical distribution systems where both live and neutral conductors require simultaneous disconnection.

Unlike a single-pole breaker that disconnects only the live conductor, the 2-pole structure disconnects both live and neutral lines during circuit interruption, providing complete electrical isolation for maintenance and system protection.

Typical applications include:

• Residential distribution boxes where complete power isolation is required for household electrical circuits.
• Commercial electrical panels used for lighting, power distribution, and equipment protection.
• Small industrial distribution systems requiring bipolar disconnection for single-phase loads.
• Main incoming switches where both live and neutral conductors need to be isolated.
• Single-phase high-power equipment such as water heaters, air conditioners, ovens, and EV charging equipment.
• Outdoor electrical cabinets and humid environments requiring additional electrical protection.

For main incoming applications, Pugao recommends using the circuit breaker together with an RCD. Additional RCD protection is recommended for circuits installed in bathrooms, outdoor areas, or water-related environments.

Flame-Retardant Materials and Internal Structure

Pugao applies flame-retardant insulating materials and high-temperature resistant copper components in the manufacturing of low-voltage circuit breakers.

Each pole integrates independent thermal and electromagnetic protection components to detect abnormal current conditions and disconnect the circuit when required.

Key Features

The main features of the breaker include:

• The two-pole design disconnects both live and neutral conductors at the same time for complete circuit isolation.
• The 6kA breaking capacity provides protection against short-circuit current conditions in low-voltage systems.
• The AC400V rated insulation voltage supports common low-voltage AC distribution applications.
• Multiple current ratings from 6A to 63A allow selection according to different load requirements.
• The 35mm DIN rail mounting structure enables installation in standard electrical distribution cabinets.
• Flame-retardant housing materials improve insulation performance during electrical operation.
• OEM customization is available for current specifications, appearance, and logo requirements.

Technical Specifications

2 Pole vs 1 Pole Circuit Breaker

A single-pole circuit breaker normally protects one live conductor, while a 2-pole circuit breaker disconnects both live and neutral conductors.

The 2-pole structure is commonly selected for distribution systems where both conductors must be isolated during maintenance or protection operation.
