Overcurrent circuit breaker, 2P, C characteristic, 16A, 10kA, AC | SU202M-C16 2CDS272337R0164

Overcurrent circuit breaker is a key element of every electrical installation, ensuring safety and protection against the effects of overloads and short circuits. This model, with a rated current of 16A and C characteristic, is perfect for securing electrical circuits in residential and commercial buildings.

Protection and reliability in practice

This two-pole (2P) circuit breaker is designed to operate in AC installations, offering effective protection against damage caused by excessive load or short circuit. The C characteristic means that the breaker reacts more slowly to short-term current surges, which is particularly important when connecting devices with electric motors or other loads with high inrush current – it will not trip unnecessarily when a refrigerator or washing machine is turned on. The rated short-circuit breaking capacity of 10kA guarantees safe disconnection of the circuit in the event of a serious failure.

Installation and compatibility

The circuit breaker is mounted on a standard TH35 rail, which facilitates its installation and replacement. Its compact size – 2 modules wide – allows for efficient use of space in the distribution board. The cross-section of the cables that can be connected to the circuit breaker is from 0.75 mm² to 25 mm² for multi-wire cables and from 0.75 mm² to 35 mm² for single-wire cables, which ensures wide compatibility with various types of installations. The IP20 degree of protection protects against accidental contact.

Additional information for professionals

The circuit breaker meets the requirements of IEC/EN 60898-1 and IEC/EN 60947-2 standards, which confirms its compliance with European safety standards. Surge category III and rated impulse withstand voltage Uimp at 4 kV provide resistance to disturbances in the electrical network. Power losses are 5W. Rated insulation voltage Ui is 440V and rated voltage is 440V. The possibility of using additional equipment increases the functionality of the circuit breaker and allows it to be adapted to the specific needs of the installation.
