2CDS213001R0505 ABB SH203-B50 Miniaturní jistič 3P B50 6kA

The ABB SH203-B50 (article 2CDS213001R0505) is a 3-pole miniature circuit breaker from the SH200 series, rated at 50 A with a B tripping characteristic. It protects three-phase AC circuits against overcurrent and short-circuit faults, with an AC breaking capacity of 6 kA.

Technical specifications:

• Series: SH200 / SH203-B50
• ABB article number: 2CDS213001R0505
• EAN: 4016779701280
• Poles: 3P
• Rated current: 50 A
• Tripping characteristic: B
• Breaking capacity (AC): 6 kA

Features and benefits:

• Three-pole design switches and protects all three phases simultaneously within a single device.
• B tripping characteristic is suited to resistive loads and circuits where inrush currents remain low.
• 50 A rated current accommodates high-demand three-phase branch circuits in distribution panels.
• 6 kA AC breaking capacity safely interrupts fault currents, limiting damage during a short-circuit event.

Applications:

• Three-phase sub-distribution boards in commercial and light industrial buildings.
• Protection of three-phase resistive heating and lighting circuits.
• Cable circuit protection inside industrial switchgear enclosures.
• Final circuit protection in office and retail distribution boards.
