3BSM000249-1 ABB Thyristor

The 3BSM000249-1 ABB Thyristor is an ABB semiconductor spare part used in industrial electrical machine applications. ABB identifies the product by Product ID 3BSM000249-1, with the ABB Type Designation and catalog description both listed as Thyristor.

 

This component is associated with ABB motor and excitation equipment and is particularly relevant to maintenance and replacement of legacy electrical machines. Available parts information places the 3BSM000249-1 alongside ABB diode and control pulse components used within the same machine-related spare-parts group.

 

 

 

The 3BSM000249-1 is not presented as a general-purpose automation control module. It is a discrete semiconductor component used as a replacement part in ABB electrical-machine equipment.

 

This distinction is useful when purchasing the component. Searching only for "ABB thyristor" can return a large number of ABB semiconductor products with different electrical characteristics and mechanical formats. The complete identifier 3BSM000249-1 is therefore the key reference for matching the required part.

 

Public ABB parts listings place 3BSM000249-1 among motor and generator service spare parts, alongside components such as 3BSM000248-1 Diode and 3BSM000313-A Control Pulse Unit.

 

 

Available technical information describes the 3BSM000249-1 as a puck-type thyristor. This is an important physical identification characteristic because industrial power semiconductors are available in several different package and mounting forms.

 

For maintenance procurement, the physical form should therefore be considered together with the ABB article number. A similarly rated semiconductor in another package should not automatically be treated as a direct replacement.

 

The associated ABB component 3BSM000248-1 is identified separately as a diode, while 3BSM000249-2 is listed as a matched pair of 1 + 1 thyristor pieces. These distinctions are useful when checking an existing machine's spare-parts list.

 

 

The 3BSM000249-1 appears in ABB motor and generator spare-parts information and is also described by independent industrial parts sources as a spare component for a synchronous motor.

 

A procurement record from an industrial end user likewise identifies 3BSM000249-1 as an ABB thyristor for an industrial electrical-machine replacement application.

 

For your website, it is therefore more accurate to describe this product around ABB electrical-machine maintenance and excitation-related replacement rather than presenting it as a generic PLC or drive component.

 

 

The following ABB part numbers are particularly relevant when checking a machine's original spare-parts list:

 

ABB Part	Description
3BSM000249-1	Thyristor
3BSM000248-1	Diode
3BSM000249-2	Thyristor, matched pair 1 + 1 pcs
3BSM000249-3	Thyristor
3BSM000313-A	Control pulse unit

 

These components appear together in available ABB motor/generator spare-parts listings. The relationship does not mean that they are interchangeable; each has its own part number and function.

 

This group could also become a useful internal-link cluster on your website if you later publish the associated ABB electrical-machine spare parts.

 

 

 

When replacing an installed thyristor, the original ABB article number should be treated as the primary identification reference:

 

ABB Product ID: 3BSM000249-1

 

The ABB Type Designation is simply:

 

Thyristor

 

Because ABB has other thyristor products under different article numbers, the generic product name alone is not sufficient for procurement.

 

Before ordering a replacement, it is useful to verify:

 

• ABB article number on the existing component
• Component type and package style
• Existing machine or excitation equipment
• Associated diode and control-pulse components
• Existing machine spare-parts documentation
• Physical arrangement of the installed semiconductor

 

For an exact replacement request, 3BSM000249-1 should be supplied rather than only "ABB thyristor."

 

 

 

Because ABB's currently accessible product record provides limited detailed electrical specifications for this individual spare part, the following table intentionally contains only information that can be supported without relying on unverified third-party ratings.

 

Parameter	Confirmed Information
ABB Product ID	3BSM000249-1
Type Designation	Thyristor
Catalog Description	Thyristor
Semiconductor Type	Thyristor
Package / Form	Puck type
Product Group	ABB Motor & Generator Service Spares
Associated Application	Electrical machine / synchronous motor spare part

 

ABB confirms the product identity, while the puck-type construction and motor-related application are supported by available industrial parts documentation.

 

Note: Some third-party listings state electrical ratings such as 910 A maximum current and 355 A average on-time current. Because I could not verify those figures in an ABB primary-source document for this exact article number, I recommend not publishing them as official specifications on your product page.

 

 

The 3BSM000249-1 is the type of component where the part number is more useful than a generic component description.

 

A search for "thyristor" can produce many unrelated ABB semiconductor products, while a search for:

 

3BSM000249-1 ABB

or

ABB 3BSM000249-1 Thyristor

 

directly identifies the required spare.

 

This is especially relevant when maintaining older synchronous motors or other ABB electrical machines where the original semiconductor components may no longer be commonly available through general electrical-component channels.

 

For spare-parts procurement, retaining the original ABB article number also helps distinguish this component from 3BSM000249-2, 3BSM000249-3, and the related 3BSM000248-1 diode.

 

 

What is ABB 3BSM000249-1?

3BSM000249-1 is an ABB Thyristor identified by ABB Product ID 3BSM000249-1.

 

What type of component is 3BSM000249-1?

It is a semiconductor thyristor, with available parts information identifying the component as a puck-type device.

 

Where is 3BSM000249-1 used?

Available ABB spare-parts information associates the component with ABB motor and generator equipment, while industrial parts documentation identifies it as a spare part for synchronous motor applications.

 

Is 3BSM000249-1 a diode?

No. 3BSM000249-1 is the thyristor. ABB spare-parts listings separately identify 3BSM000248-1 as the diode.

 

What is the difference between 3BSM000249-1 and 3BSM000249-2?

Available ABB parts listings identify 3BSM000249-2 as a matched pair of 1 + 1 thyristor pieces, while 3BSM000249-1 is listed simply as the thyristor.

 

Is 3BSM000249-1 the same as 3BSM000249-3?

They are listed as separate ABB article numbers, even though both are described as thyristors. They should therefore not be treated as interchangeable without checking the applicable machine and spare-parts documentation.

 

How should I identify the correct replacement?

Use the complete ABB article number 3BSM000249-1 together with the existing machine or excitation-system information. The generic term "ABB thyristor" is not sufficient to distinguish among ABB's different semiconductor spare parts.
