INSTALLATION

MOUNTING THE CIRCUIT BREAKER TO A PANEL

The circuit breakers are designed to mount to a panel made from 11 ga. (.12 in.) thick steel. If the breaker must be mounted to a panel of different thickness, contact Toshiba.

Panel cutout dimensions for the circuit breakers are given in Fig. 12. One cutout size is used for all breaker types.

To mount the circuit breaker, follow the steps below:

1.Loosen the small screw (M5) on the closing handle and remove the handle.

2.Remove the four front plate mounting bolts (M8) from the circuit breaker (Fig. 9). Remove the spacer washers between the front plate and breaker and discard them (make sure none are left inside the breaker),

3.Align the breaker with the cutout and mounting holes on the panel to which it is to be mounted (Fig. 10). Some breakers are furnished with two hooks which may be used to temporarily attach the breaker to the panel.

4.Using the four M8 bolts removed in step 2, fasten the breaker and its front plate to the mounting panel (Fig. 11). The tightening torque should be 120-150 kgf-cm (9-11 ft-lb).

5.Replace the closing handle removed in step 1 and the M5 screw. The screw should be tightened to a torque of 40-50 kgf-cm (35-43 in-lb).

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.
