2CDS253001R0165 ABB SH203-B16 MCB 3P 16A B Curve 6kA DIN Rail

The ABB S203-B16 (article 2CDS253001R0165) is a 3-pole miniature circuit breaker from the System pro M compact S200 series. Rated at 16 A with a B tripping characteristic and a breaking capacity of 6 kA AC, it delivers both overload and short-circuit protection in one compact device suitable for a wide range of installation types.

Technical specifications:

• Series: S203-B16 (S200)
• ABB article number: 2CDS253001R0165
• EAN: 4016779469005
• Poles: 3P
• Rated current: 16 A
• Tripping characteristic: B
• Breaking capacity (AC): 6 kA
• Rated voltage: 230/400 V AC

Features and benefits:

• Current-limiting construction restricts let-through energy during fault events, reducing thermal and mechanical stress on downstream wiring and equipment
• Two separate tripping mechanisms operate independently - a delayed thermal element handles sustained overloads while an electromechanical element responds to short circuits
• B tripping characteristic is well matched to resistive and lightly inductive loads where inrush currents are low
• Meets IEC/EN 60898-1, IEC/EN 60947-2, and UL1077, covering residential, commercial, and industrial application requirements
• Accepts a bottom-fitting auxiliary contact without requiring extra width, saving up to 50% of the space a side-mounted accessory would occupy

Applications:

• Overcurrent protection in residential distribution boards and consumer units
• Branch circuit protection in commercial buildings and office fit-outs
• 3-pole circuit protection in light industrial control and distribution panels
• Protection of 3-phase loads and final circuits in mixed-use installations
