Overcurrent circuit breaker, 4P, C characteristic, 25A, 10kA, AC | S204M-C25 2CDS274001R0254

Overcurrent switch – reliable protection of electrical installations

This four-pole overcurrent switch with C characteristic is a key element of every safe and efficient electrical installation. It provides effective protection against overloads and short circuits, protecting both devices and people. It is an ideal solution for both installers and end-users looking for reliable protection.

Characteristics and application

The S204M-C25 switch is designed to protect electrical circuits with a rated current of 25A. The C characteristic means that the switch reacts more slowly to short-term current surges, which is particularly important when starting devices with motors or other loads with high inrush current. This minimizes the risk of unnecessary tripping of the circuit during normal operation. The rated short-circuit breaking capacity of 10kA (at 400V) guarantees safety in the event of serious disturbances in the network.

Advantages and benefits

• Versatility: The possibility of mounting on a DIN rail makes the switch compatible with most electrical distribution boards.
• Safety: Compliance with EN 60898 and IEC 60947-2 standards ensures a high level of safety.
• Durability: Made of high-quality materials guarantees long life and reliable operation.
• Flexibility: The possibility of connecting wires with a cross-section from 0.75 mm² to 25 mm² (multi-strand) and from 0.75 mm² to 35 mm² (solid) gives great freedom in choosing wires.
• Wide temperature range: Operation in the temperature range from -25°C to 55°C allows the switch to be used in various environmental conditions.
• Compact dimensions: A width of 4 modules makes it easy to install even in tight distribution boards.
• Overvoltage protection: Rated impulse withstand voltage Uimp at 4kV increases resistance to sudden voltage surges.

Additionally, limitation class 3 indicates the switch's ability to limit short-circuit energy, which translates into less damage to the installation and equipment in the event of a failure. Power losses of 12.8 W are relatively low, which affects the energy efficiency of the system. Protection degree IP20 provides protection against accidental contact and against the ingress of solid objects larger than 12.5 mm.
