GE IS210JPDDG1A - POWER DISTRIBUTION BOARD

OVERVIEW

DEFINITION AND FUNCTION: The GE IS210JPDDG1A - POWER DISTRIBUTION BOARD is a key device for power distribution manufactured by General Electric (GE). Its primary function is to efficiently distribute incoming power to multiple output branches, ensuring that each connected electrical device receives the appropriate power supply. In complex industrial electrical systems or other situations where centralised power distribution is required, the distribution board plays a vital role, acting as a hub for power distribution, managing and controlling the flow of power.

Principle of operation

Power input: The switchboard receives power from the mains (e.g. utility or industrial generator output). This input power is usually higher voltage and higher current alternating current (AC), for example, a common three-phase four-wire AC power supply, the line voltage may be 380V - 400V, the phase voltage is 220V or so. The incoming AC power passes through protective devices such as fuses or circuit breakers and enters the main busbar of the distribution board.

Distribution mechanism: The main bus distributes the power to several branches, each with its own protective device (e.g. small circuit breaker, fuse, etc.) and output connections. When power is required for an electrical device, the device is connected to the output connector of the distribution board via a suitable cable. The distribution board distributes the power from the mains supply to each branch circuit in a reasonable manner according to the power demand and electrical characteristics of the equipment connected to each branch circuit. For example, if a branch circuit is connected to a device with a power of 1kW, the distribution board will distribute the corresponding power to this branch circuit according to the rated voltage and current of the device through suitable wiring and protection devices.

Protection Principle: Protective devices play a key role in the power distribution process. Fuses cut off the circuit when the current exceeds the rated value by melting the fuse inside, preventing damage to equipment and wiring caused by overload currents. Circuit breakers, on the other hand, quickly cut off circuits in the event of short circuits or overloads through mechanisms such as electromagnetic disconnection and thermal disconnection. For example, when a short-circuit fault occurs in a branch circuit and the current increases instantaneously, the circuit breaker will trip in a very short time (usually between a few milliseconds and tens of milliseconds) to protect the downstream equipment and the entire power distribution system.

Performance Features

High load capacity: This distribution panel has a high load capacity and can withstand large total power. It may have a total power capacity of several kilowatts (kW) to tens of kW, depending on its design and specifications. This allows it to power multiple high power devices simultaneously, such as multiple motors, processing equipment, etc. in a small factory.

Multi-branch design: has multiple output branches, which may range from a few to dozens. This multi-branch design increases the flexibility and scalability of power distribution and can meet the needs of power distribution of different sizes and complexity. For example, in the power distribution system of an office building, separate branch circuits can be provided for lighting, sockets and office equipment on different floors and in different rooms.

Reliable protection: Equipped with a variety of reliable protection devices, such as fuses and circuit breakers, which have different current ratings and action characteristics, they can effectively protect the equipment from damage caused by electrical faults such as overloads and short circuits. At the same time, the fast action speed of the protective devices can cut off the circuit in time at the moment of the fault, reducing the impact of the fault on the equipment and system.

Safety and Compliance: Strict electrical safety standards and codes are followed during the design and manufacturing process. It has good insulating properties and can prevent electric shock accidents. Meanwhile, the distribution board is clearly labelled with information such as branch number, rated voltage, rated current, etc., which facilitates installation, maintenance and operation and ensures compliance with relevant electrical safety regulations and standards.

Technical Parameters

Input parameters

Input Voltage Range: Usually can accept a wide range of input voltages to adapt to different grid voltage fluctuations. For example, for a three-phase AC input, the line voltage range may be 340V - 440V and the phase voltage range 190V - 240V, ensuring that the unit can still function properly when the grid voltage varies.

Input Frequency Range: Suitable for standard grid frequencies, typically 50Hz - 60Hz, to enable stable reception and distribution of power within this frequency range.

Maximum input current: the maximum input current depends on the power capacity of the switchboard, for example, for a switchboard with a total power of 30kW, with a three-phase four-wire input (line voltage of 380V), the maximum input current is about 45.6A according to the formula (where is the power, is the line voltage and is the current).

Output parameters

Branch output voltage range: the output voltage of each branch is basically the same as the input voltage, but there will be a certain voltage drop, usually the branch output voltage fluctuation range is within ±5% - ±10% of the rated voltage, for example, the rated voltage is 220V branch, the output voltage range may be between 198V - 242V.

Tributary Output Current Range: Each tributary has its own current rating, which may range from a few amperes (A) to several tens of amperes, depending on the purpose for which the tributary is designed and the power requirements of the connected equipment. For example, a branch circuit used for lighting may have a current rating of about 10A, while a branch circuit used to power a motor may have a current rating of 30A.

Number of branches and power distribution: The number of branches may range from 4 - 30, depending on the model. The power distribution is based on the load capacity of the branch circuits and the user's demand, allowing flexibility in distributing power to devices with different power levels. For example, for a distribution board with a total power of 20kW, 10kW may be allocated to 4 higher power branches, with 2.5kW equally allocated to each branch and the remaining 10kW to a number of other lower power branches.

Physical Parameters

Dimensions: External dimensions generally vary depending on the installation environment and power capacity. The length may be between 30cm - 80cm, the width between 20cm - 60cm and the thickness between 10cm - 30cm, which makes it easy to install in a distribution box or electrical control cabinet.

Weight: The weight is usually between 5kg - 30kg, the heavier weight is mainly due to the heavier electrical components such as copper busbars, circuit breakers, etc. The weight is also related to the power capacity and size of the switchboard.

Environmental parameters

Operating temperature range: able to work in a wide range of temperatures, generally - 10 ℃ - + 50 ℃, in this temperature range can be stable power distribution, to adapt to different indoor and industrial environment temperature.

Humidity range: Relative humidity range is typically 10% - 90% (non-condensing), ensuring normal operation in different humidity conditions and avoiding electrical failures due to humidity problems.
