Overcurrent circuit breaker, 4P, C characteristic, 16A, 10kA, AC | S204M-C16 2CDS274001R0164

Electrical installation protection with S204M-C16 circuit breaker

This four-pole overcurrent circuit breaker from the S204M series by ABB is a reliable protection for your electrical installation. Designed to protect circuits against overload and short circuit, it ensures safe use and minimizes the risk of failure. Characteristic C makes it ideal for circuits with devices generating surge currents, such as motors or transformers – it allows it to react more slowly to short current spikes, while effectively protecting against prolonged overload. The rated current of 16A makes it a popular choice for securing standard lighting and socket circuits.

This circuit breaker is characterized by a high short-circuit breaking capacity, reaching 10kA at 230V and 15kA at 400V, which guarantees effective intervention in the event of serious disturbances. Mounting on a TH35 DIN rail simplifies and speeds up installation, and the compact dimensions (4 modules wide) allow for efficient use of space in the switchgear cabinet. Energy limitation class 3 provides additional safety in the event of an electric arc.

Application and structural features

The S204M-C16 circuit breaker is used in a wide range of electrical installations – both in residential and commercial buildings. Its solid construction and compliance with IEC EN 60898 and IEC EN 60947-2 standards guarantee reliable operation for a long time. The cross-section of the connected conductors from 0.75 mm² to 25 mm² (multi-strand) and from 0.75 mm² to 35 mm² (single-strand) provides flexibility in connecting different types of conductors. Protection degree IP20 protects against accidental contact, but does not provide protection against water or dust – therefore, the circuit breaker should be mounted in dry and closed rooms. The ambient temperature in the range of -25°C to +55°C allows it to be used in various climatic conditions. Additionally, the possibility of mounting additional equipment increases the functionality of the circuit breaker and allows it to be adapted to the specific needs of the installation.
