Residual current circuit breaker with overcurrent protection KZS-2M AC B16/0.3 002173304

Residual Current Device with Overcurrent Protection KZS-2M is a reliable device that combines protection against electric shock and overcurrent protection. It is a key element of any electrical installation, ensuring the safety of people and equipment. The device is designed for use in circuits with a voltage of 230V, and its rated current is 16A.

The construction of the circuit breaker is based on AC technology, which means it reacts to alternating differential currents. Characteristic B provides fast tripping in the event of short circuits and overloads, protecting the installation from damage. The rated differential current set at 0.3A guarantees effective protection against electric shock.

Mounting is done on a DIN rail, which simplifies and speeds up installation. Compact dimensions – only 2 modules wide – allow for efficient use of space in the switchgear cabinet. The circuit breaker has a protection degree of IP20, which means it is protected against touching with a finger and the ingress of solid objects.

Application and functionality

The KZS-2M circuit breaker finds application in a wide range of electrical installations – both in residential and commercial buildings. It can be used in lighting circuits, socket circuits, and in protecting electrical devices of various powers. Thanks to the simultaneous disconnection of the N pole, it provides complete protection against electric shock.

Constructional features and parameters

The device is characterized by high quality of workmanship and durability. The rated short-circuit breaking capacity is 10kA, which guarantees effective protection in the event of a short circuit. The cross-section of the connectable single-wire and multi-wire conductors is from 1 to 25 mm², which allows connecting conductors of different thicknesses. The test button allows regular checking of the correct operation of the residual current device, ensuring continuous protection of the installation. Additionally, energy limitation class 3 indicates high resistance to short-circuit energy.

The KZS-2M circuit breaker complies with IEC/EN 61009 standards, which confirms its safety and reliability. Operation in an ambient temperature from -25°C to +40°C means that the device can be used in various climatic conditions.
