The Small Circuit Breaker 4P is a miniature 4-pole circuit breaker, specifically designed for three-phase four-wire (380V/220V) branch circuits. It adopts a standard modular structure, which can synchronously cut off the three-phase and neutral lines, providing overload and short-circuit protection. The product is easy to install and suitable for small commercial, workshop power boxes and residential scenarios, etc. It can achieve complete isolation of three-phase systems and basic protection of circuits with an economical choice.Small Circuit Breaker 4P: Economical three-phase four-wire miniature circuit breaker In scenarios such as small commercial premises, workshop power cabinets or three-phase residential incoming lines, branch circuits require reliable, economical and space-saving protection solutions. The Small Circuit Breaker 4P is precisely the product designed for this purpose. It adopts a modular structure, which can synchronously control and protect three-phase lines and neutral lines, provide overload and short-circuit protection, and ensure operational safety with complete electrical isolation. It is a fundamental electrical component for building a safe three-phase power distribution system.

The Molded case leakage circuit breaker 125A 4P is a core device specifically designed to provide ground fault protection for three-phase four-wire systems. It integrates the high breaking capacity of a plastic-enclosed circuit breaker with sensitive leakage protection functionality. It can reliably break overload and short-circuit currents at a 125A current rating and simultaneously detect and cut off leakage faults that may cause electric shock or electrical fires. Its four-pole synchronous breaking design ensures complete isolation of the three phases and neutral line, making it suitable for main or branch circuits in industrial workshops, commercial buildings, and new energy charging stations where strict safety protection requirements are in place.

The Universal Circuit Breaker Fixed Type 2000A 3P is suitable for use in distribution networks to distribute electrical energy, protect lines, and prevent faults such as overvoltage, undervoltage, short circuit, and single-phase grounding of power equipment. This product features an intelligent protection function for electrical appliances, preventing unnecessary power outages.

The iron indoor base boxes manufactured by China Ouyue Electrical Factory can help people solve the problem of indoor electrical installation. They are specially designed for indoor electrical installation in residential areas, commercial areas or industrial areas. The box body is made of high-quality iron and its surface has undergone anti-rust treatment, making the product structure sturdy. The factory offers standard specifications in stock and supports customized sizes for different requirements.

The Universal Circuit Breaker Drawer Type 6300A 3P adopts a drawer-type plug-in structure. When the fixed circuit breaker body is installed into the dedicated drawer seat, it becomes the Universal Circuit Breaker Drawer Type 6300A 3P. It enables the circuit breaker to be installed, tested and replaced quickly. We can offer both in-stock and customized services.

The Universal Circuit Breaker Fixed Type 3200A 3P product is a device used for core protection in power distribution systems. It adopts an integrated fixed installation structure, with the circuit breaker body directly assembled within the frame of the distribution cabinet. This product is suitable for long-term operation power distribution scenarios, such as critical circuit loop protection in fixed power distribution and main power distribution cabinets of infrastructure.
