Overcurrent circuit breaker, 3P, B characteristic, 16A, 10kA, AC | S203M-B16 2CDS273001R0165

Reliable protection of electrical installations with S200 series circuit breaker

This three-pole circuit breaker with B characteristic is a key element of every safe electrical installation. It provides effective protection against overloads and short circuits, guaranteeing continuous operation and minimizing the risk of failure. Suitable for use in AC networks with a voltage of 400V, as well as 230V, it will work both in home and commercial installations.

The S203M-B16 circuit breaker is characterized by a high short-circuit breaking capacity – up to 10kA at 400V and 230V and 15kA/25kA (depending on the standard) – which translates into a quick response in emergency situations and limitation of potential damage. The design based on the proven B characteristic means that the circuit breaker reacts quickly to short-term current surges, but is resistant to temporary overloads associated with starting devices with high power consumption, such as motors.

Solid construction and wide application

The circuit breaker occupies 3 modules on a DIN rail, which facilitates installation and integration with existing electrical infrastructure. The cross-section of conductors from 0.75 mm² to 35 mm² (solid) and 25 mm² (stranded) provides great flexibility in selecting the appropriate cables. A wide range of operating temperatures (-25°C to +55°C) allows it to be used in various environmental conditions.

• High reliability: Energy limitation class 3 and surge category III ensure stable operation even in difficult network conditions.
• Versatility: Suitable for protecting circuits with a rated current of 16A in AC installations with a voltage of up to 400V.
• Safety: Rated impulse withstand voltage Uimp is as high as 4kV, which increases resistance to sudden voltage surges.
• Easy installation: Compact dimensions (installation depth 69 mm) and DIN rail mounting facilitate installation and servicing.
• Expandability: Compatibility with additional equipment allows the circuit breaker to be adapted to specific installation needs.

The S203M-B16 circuit breaker is a solid and effective solution for every installer and end-user looking for reliable protection of their electrical installation. Its design meets the requirements of EN 60898 and IEC 60947-2 standards, which guarantees safety and compliance with applicable regulations.
