American branch box

Compliant with NEC standards, it highlights high current-carrying capacity and modular design. The cabinet is mostly made of cold-rolled steel plate with spraying process. The internal drawer-type switch modules facilitate quick maintenance and expansion. It has a high short-time withstand current rating, integrates lightning and surge protection functions, and is mainly installed in floor-mounted ways, suitable for North American high-current distribution needs and American cable interfaces.

European branch box

Compliant with BS standards, it focuses on compact structure and outdoor weather resistance. Mostly made of stainless steel or glass fiber, its protection class is ≥IP65, suitable for humid and foggy environments. The electrical design emphasizes circuit isolation and overload protection, equipped with standard fuses and grounding terminals. Mainly installed in wall-mounted and pole-mounted ways, it conforms to the low-voltage distribution specifications of Commonwealth countries.

Cable Branch Box Overview

• With a rated current of up to 1250A and a short-time withstand current of 31.5kA/3s, it can stably bear the instantaneous load impact of high-power electrical scenarios such as factory production lines and heavy-duty equipment, meeting the power distribution needs of multiple circuits operating simultaneously and avoiding power outages caused by overload.
• Designed with IP66 protection class, the cabinet is made of 304 stainless steel treated by pickling phosphating + electrostatic spraying process, with anti-rust and anti-corrosion grade up to C5-M standard. It can withstand extreme ambient temperatures of -40℃~+70℃, and has excellent dustproof, waterproof and anti-mechanical impact performance, suitable for the complex working conditions of dusty, humid and large temperature difference in factory workshops.

Flexible Customization & Modular Design

• It supports flexible customization of 1-4 incoming circuits and 8-24 outgoing circuits. Each outgoing circuit can be independently equipped with overload protection and short-circuit protection modules, with a circuit switching response time of ≤0.1s. It can accurately match the power distribution needs of different areas and equipment in the factory, and the number of circuits can be increased at any time according to the expansion of the production line.
• Adopting a drawer-type modular design, the core electrical components can be quickly plugged and replaced. No overall power outage is required during maintenance, and the maintenance time of a single module is ≤15 minutes, which greatly reduces the factory downtime loss. The internal wiring is organized in separate trunking areas with clear wire harness identification, reducing the failure rate by more than 30%.

Real-Time Monitoring & Heat Dissipation

• Integrated with real-time monitoring modules for voltage, current and temperature, the data collection accuracy is ≤±0.5%. It can be linked with the factory's intelligent power distribution system through the RS485 communication interface to realize real-time alarm (response time ≤3s) for abnormalities such as overload, over-temperature and leakage, early warning of potential faults, and the power supply reliability is improved to 99.9%.
• The cabinet adopts a composite heat dissipation structure with upper and lower double vents + built-in cooling fans, which improves the heat dissipation efficiency by 40% and can control the working temperature of internal components within +15℃ of the ambient temperature. The fan start-up temperature can be intelligently set (default 45℃), reducing energy consumption by 25% and extending the service life of core components to more than 10 years.
