Overcurrent circuit breaker 10 kA, In=32 A, characteristic C, 3+N pole PLSM PLSM-C32/3N-MW 242546

Overcurrent circuit breakers – reliable protection for electrical installations

This three-pole overcurrent circuit breaker with an additional neutral pole (3+N) is a key element of every safe and efficient electrical installation. Designed to protect circuits against overload and short circuit, it provides reliable operation in homes, commercial and industrial buildings. Characteristic C makes it ideal for circuits with high inrush current, such as motors or transformers – it allows it to react more slowly to short current surges, therefore it tolerates starting devices with a motor well. The rated short-circuit breaking capacity of 10 kA guarantees effective protection even in the event of serious failures.

This circuit breaker is characterized by a wide range of applications, from protecting lighting and sockets in residential buildings to protecting more demanding circuits in industrial facilities. The possibility of connecting wires with a cross-section from 1 to 25 mm² provides flexibility during installation and adaptation to various needs. The compact width of 4 modules makes it easy to install in switchboards with limited space.

Construction features and operating parameters

The circuit breaker is designed for durability and reliability. The degree of protection IP20 means that it is protected against finger contact, which increases safety. Made of high-quality materials, resistant to environmental conditions, it ensures long-term operation at temperatures from -25°C to 75°C. The rated insulation voltage Ui at 440 V and the rated impulse withstand voltage Uimp 4 kV guarantee safety even in difficult operating conditions. Additionally, the possibility of mounting additional equipment allows for expanding the functionality of the circuit breaker and adapting it to specific installation requirements.

The use of a circuit breaker with characteristic C is particularly important where there are devices generating surge currents during start-up – this prevents unnecessary tripping of the circuit breaker and ensures continuity of power supply. At the same time, its high short-circuit breaking capacity (10 kA at 230 V and 400 V) minimizes the risk of damage to the installation in the event of a short circuit. Power losses of 11.8 W indicate the energy efficiency of the device.
