Why Choose the ABB 1SDA100262R1 XT4V 250 Breaking Part?
The ABB 1SDA100262R1 is a Tmax XT4V 250 breaking part designed for use within ABB's XT4 moulded case circuit breaker platform. It features a 250 A rated uninterrupted current, 3-pole fixed construction and front terminals, providing the high-performance interruption section required when assembling a compatible XT4V circuit breaker.
The V short-circuit performance level is engineered for electrical distribution systems with high prospective fault currents. The XT4V 250 provides a rated ultimate short-circuit breaking capacity of 150 kA at 415 V AC, making it suitable for demanding industrial, commercial and infrastructure installations where robust fault interruption is essential.
The 1SDA100262R1 is supplied as the breaking part rather than a complete protective circuit breaker. A compatible ABB XT4 trip unit must be selected separately to create the required complete breaker configuration, allowing the protection characteristics to be matched to the electrical installation while retaining the XT4V platform's high breaking capacity.
Key Advantages
- High-performance ABB Tmax XT4V breaking part for moulded case circuit breaker assemblies.
- 250 A rated uninterrupted current for substantial low-voltage distribution loads.
- 150 kA ultimate short-circuit breaking capacity at 415 V AC.
- V short-circuit performance level for installations with high prospective fault currents.
- Suitable for both AC and DC electrical systems within its specified ratings.
- 3-pole fixed construction with front terminals for straightforward switchboard integration.
- Allows a compatible ABB XT4 trip unit to be selected separately according to the required protection characteristics.
Key Features
- ABB Tmax XT4V 250 breaking-part platform.
- 250 A rated uninterrupted current (Iu).
- V high-breaking-capacity performance level.
- 150 kA rated ultimate short-circuit breaking capacity (Icu) at 415 V AC.
- 690 V AC rated operational voltage.
- 750 V DC rated operational voltage.
- 1,000 V rated insulation voltage (Ui).
- 8 kV rated impulse withstand voltage (Uimp).
- 3-pole configuration for three-phase electrical systems.
- Fixed installation with front terminal connections.
- Designed to accept a separately ordered compatible ABB XT4 trip unit.
- Compliant with IEC circuit-breaker requirements.
High Fault-Level Protection with the XT4V Platform
The breaking part forms the interruption section of a modular ABB Tmax XT4V circuit breaker assembly. Its function is to safely interrupt fault current when operated by the associated protection trip unit, while the separately selected trip unit determines the overload and short-circuit protection characteristics required for the installation.
With rated service and ultimate short-circuit breaking capacities of 150 kA at 415 V AC, the XT4V 250 platform is designed for electrical systems where prospective fault currents can be substantially higher than those encountered in conventional distribution applications. Combining the 1SDA100262R1 with a compatible ABB XT4 trip unit creates a complete protective circuit breaker tailored to the required application.
Typical Applications
- Industrial low-voltage distribution systems.
- High-fault-level electrical switchboards.
- Main and sub-distribution panels.
- Commercial and infrastructure power distribution.
- Transformer and generator distribution systems.
- OEM switchgear and electrical distribution assemblies.
