Product Description P/N: T4N250BW
Description
The ABB T4N250BW is a three-pole molded case circuit breaker rated at 250 A for AC power-distribution circuits up to 600 VAC. It uses a PR221DS-LS/I electronic trip unit to provide overload protection and selectable short-circuit protection. The fixed-mounted breaker is intended for compatible switchboards, panelboards, and industrial distribution assemblies.

Information About T4N250BW
The T4N250BW is part of ABB’s SACE Tmax T4 family and carries the N short-circuit performance classification. Its solid-state release provides long-time protection together with a choice of short-time or instantaneous short-circuit operation. The assembly uses front terminals for connection to the surrounding distribution equipment. ABB identifies this catalog number with product code 1SDA055413R1 and specifies UL 489 and CSA C22.2 compliance.
Key Features:
- Three-Pole Construction: Switches and protects three conductors through a common breaker mechanism.
- Rated Current: Provides a 250 A rating within the Tmax T4 frame.
- AC Circuit Application: Uses an electronic trip configuration specified for AC operation.
- Electronic Overload Protection: Provides adjustable long-time protection through the PR221DS-LS/I release.
- Selectable Short-Circuit Function: Offers short-time or instantaneous protection as alternative settings.
- Interrupting Capacity: Rated at 65 kA at 240 VAC, 25 kA at 480 VAC, and 18 kA at 600 VAC.
- Fixed Installation: Supports panel mounting within compatible electrical distribution assemblies.
- Front Terminal Access: Provides front connections; cable lugs require separate selection.
The T4N250BW delivers the reliability and precision required for overload and short-circuit protection in industrial AC power-distribution systems.
