2CDS253001R0505 ABB SH203-B50 MCB 3P 50A B Curve 6kA DIN Rail

ABB S203-B50 (article 2CDS253001R0505) is a 3-pole, 50 A miniature circuit breaker from the S200 System pro M compact range, providing protection against both overload and short-circuit faults on AC systems. With a 6 kA breaking capacity and B tripping characteristic, it is a current limiting device suitable for residential, commercial, and industrial circuits.

Technical specifications:

• Series: S203-B50 (S200 System pro M compact)
• ABB article number: 2CDS253001R0505
• EAN: 4016779550963
• Rated current: 50 A
• Number of poles: 3P
• Tripping characteristic: B
• Breaking capacity: 6 kA (AC)
• System voltage: 230/400 V AC

Features and benefits:

• Current limiting design reduces the energy let through during a fault, helping to protect downstream equipment
• Two independent tripping mechanisms - a delayed thermal element for sustained overload conditions and an electromechanical element for fast short-circuit response
• B tripping characteristic suited to resistive and lightly inductive loads
• Complies with IEC/EN 60898-1, IEC/EN 60947-2, and UL1077, covering residential, commercial, and industrial application requirements
• Accepts a bottom-fitting auxiliary contact that saves 50% of the space needed by conventional side-mounted accessories

Applications:

• Protection of 3-phase circuits in residential consumer units and distribution boards
• Cable and equipment protection in commercial electrical installations
• Sub-distribution and circuit protection in industrial control panels
• 3-phase overcurrent protection in mixed residential and light commercial buildings
