400 Amp Power Distro

Design and Structural Highlights

Protective Enclosure: High-strength, rotationally molded engineering plastic housing; drop-resistant, shock-resistant, waterproof, and dustproof-suitable for demanding outdoor environments.

Mobile Design: Equipped with silent swivel casters at the base for easy on-site transport and setup.

Tiered Socket Layout: Sockets are arranged in rows by current rating (top to bottom), distinguishing between single-phase/three-phase and low-power/high-power circuits to simplify wiring and maintenance:

Upper-tier small blue sockets: Primarily 16A single-phase industrial sockets for powering small equipment.
Red flip-cover sockets: Medium-power three-phase circuits.

Large-format red-and-silver industrial sockets: High-power three-phase output (32A/63A ratings).

Bottom-tier multi-specification colored sockets: Compatible with diverse loads, including Chinese standard, European standard, and specialized lighting interfaces.

Usage Recommendations

When distributing loads on-site, balance the three-phase loads as much as possible to avoid single-phase overloading.
Prioritize assigning 63A high-power circuits to large display screens and high-power lighting arrays.
Reserve 16A circuits exclusively for low-power, precision equipment such as control consoles and laptops.
When using the unit outdoors in rainy conditions, ensure the cabinet door is securely closed and the dustproof/waterproof socket covers are shut.

Product Advantages

✅ Integrated design replaces scattered terminal blocks, resulting in neater on-site wiring and enhanced safety redundancy;

 

✅ Independent circuit protection ensures that a fault in one channel does not disrupt the power supply to other circuits in the unit;

 

✅ The rotationally molded (rotomolded) housing is impact-resistant, making it ideal for the frequent handling and touring demands of the live performance industry.

1: Does the 400A rating refer to a single-phase 400A or a total three-phase 400A capacity? What is the maximum load (in kilowatts) it can handle?

It refers to a total three-phase input of 400A (3-phase, 5-wire: 3P+N+PE). Under standard industrial 400V operating conditions, the unit's rated power capacity is approximately 277 kW. However, in actual operation, not all sockets should be fully loaded simultaneously; since stage equipment usage involves staggered power demands, it is recommended to keep the total actual load within 220 kW to maintain a safety margin.

2: Are the blue 16A sockets inside the cabinet three-phase or single-phase, and what is the voltage?

They are all 230V single-phase industrial sockets (2-pin + ground), suitable for low-power equipment such as control consoles, computers, routers, and small fill lights; each circuit is rated at 3.68 kW.

3: How many pins do the red-capped 32A and 63A sockets have, and what equipment do they suit?

They are all 5-pin three-phase industrial sockets (3 phases + neutral + ground; IEC 60309 standard). The 32A circuit (22 kW) is suitable for small-to-medium moving-head lights and line-array speaker amplifiers. The 63A circuit (43.6 kW) is suitable for complete LED video wall systems, high-power beam light arrays, and main sound reinforcement systems.
