Terasaki 400A 3P MCCB

The Terasaki 400A 3P MCCB is a high-current moulded case circuit breaker designed for electrical distribution and protection applications where a higher current rating is required. With a 400A rating and three-pole configuration, it is intended for compatible three-phase AC systems used in commercial, industrial and larger electrical installations.

A 400A MCCB is typically selected for applications where the current requirements are beyond the range of smaller miniature circuit breakers. The three-pole arrangement allows the breaker to be used in suitable three-phase distribution systems, providing controlled circuit protection and isolation when correctly specified for the installation.

Terasaki is an established manufacturer of low-voltage circuit protection and switchgear equipment, and its MCCB range is used in electrical distribution applications. However, the exact performance of a Terasaki breaker depends on the specific series and model. Before purchasing, customers should confirm the model number, rated operational voltage, breaking capacity, trip-unit configuration and other technical specifications shown on the actual product or manufacturer documentation.

The Terasaki 400A 3P MCCB can be considered for applications such as commercial electrical panels, industrial distribution boards, power-distribution systems and suitable solar or inverter AC output installations. A Pakistani public-sector solar procurement document, for example, specifies 400A MCCBs for combining AC inverter outputs, demonstrating the type of high-current application in which this rating can be used.

When selecting a 400A breaker, the current rating should not be considered in isolation. Cable size, prospective fault current, system voltage, load characteristics, coordination with upstream and downstream protection, and the required breaking capacity should all be considered by a qualified electrical professional.

If you are looking for a Terasaki 400A 3P MCCB in Pakistan, HN Electric can provide availability and pricing according to the exact model in stock. Customers in Lahore and other cities can contact HN Electric to confirm the model and technical specifications before placing an order.

For project requirements, also confirm whether you require a fixed or adjustable trip configuration and whether any accessories such as auxiliary contacts, shunt trip or undervoltage release are required. These details can vary between Terasaki MCCB series and should be matched to the electrical panel design.

FAQ

Q1. What is a Terasaki 400A 3P MCCB used for?
It is designed for high-current circuit protection and isolation in compatible three-phase AC distribution systems, including commercial and industrial electrical installations.

Q2. What does 3P mean on a 400A MCCB?
3P means the breaker has three poles and is intended for appropriate three-phase electrical systems.

Q3. Is every Terasaki 400A MCCB the same?
No. Terasaki has multiple MCCB series and models. Breaking capacity, voltage, trip characteristics and accessories can differ, so the exact model should be confirmed before purchase.
