WARNING

Do not install this equipment in areas where unusual service conditions exist. Using this equipment in other than usual service conditions can result in equipment failure.

at the installation location, a space heater should be installed inside the circuit breaker enclosure.

NOTE: Temperature, altitude or other conditions outside of the usual limits may require derating or other special equipment. Contact your nearest Toshiba representative for additional

Toshiba HV6AS circuit breakers are intended for use in usual service conditions as defined in IEEE C37.20.2. The temperature of the cooling air (ambient air temperature) surrounding the breaker should be between the limits of -5°C (23°F) and +40°C (104°F). The altitude of the equipment installation should not exceed 3300 ft (1000 m).

In particular, avoid the following installation conditions:

information.

RATING VERIFICATION

Prior to Installation, the maximum fault current capacity of the power system at the point of installation should be verified. This value must not exceed the symmetrical interrupting capability of the circuit breaker. Fig. 8 illustrates a typical circuit breaker nameplate.

-Excessive dust

-Corrosive gases

-Extreme variations in temperature

-Very high or low humidity

-Vibrations

-Inclined locations

If there is a chance that condensation can occur

HV6AS specifications

The Toshiba HV6AS is a sophisticated high-voltage IGBT (Insulated Gate Bipolar Transistor) module, primarily designed for demanding applications in industrial and energy sectors. This module stands out due to its superior performance characteristics, which allow it to handle high voltages while delivering optimal efficiency and reliability.

One of the key features of the HV6AS is its high voltage rating, typically around 650V, making it suitable for various applications including motor drives, renewable energy systems, and UPS (Uninterruptible Power Supply) systems. This voltage capacity enables the module to effectively control large power loads, ensuring excellent performance in high-demand environments.

The HV6AS adopts cutting-edge technologies that improve its operational efficiency. The design incorporates advanced thermal management features, which help in enhancing its reliability and lifespan. Integrated with a robust heat sink, the module efficiently dissipates heat generated during operation. This is crucial as increased temperatures can lead to reduced performance and potential failure.

Additionally, the HV6AS utilizes a double-sided cooling structure, which allows for superior thermal conductivity and enables the module to perform optimally in high-temperature conditions. This aspect is particularly important for applications in renewable energy, such as solar inverters, where efficiency and durability are key.

Another notable characteristic of the HV6AS is its fast switching capability. The IGBT technology allows for rapid switching between on/off states. This feature is essential in applications such as pulse-width modulation (PWM), contributing to improved power conversion efficiency. The high switching frequency capability means that systems can operate more efficiently, resulting in lower energy losses.

Toshiba’s HV6AS also focuses on enhancing productivity through simplified circuit design. Its compact form factor means that it can be easily integrated into existing systems, saving space and simplifying installation processes. The module’s compatibility with existing drive technologies allows for seamless upgrades to newer systems without significant changes to the overall architecture.

In summary, the Toshiba HV6AS is a highly versatile IGBT module characterized by its high voltage capability, advanced thermal management, fast switching speed, and compact design. These factors make it an excellent choice for a wide array of high-performance applications in various industries, driving innovation towards more efficient and sustainable power solutions. Whether in industrial automation or renewable energy, the HV6AS sets a benchmark for reliability and effectiveness in power electronics.
