Selective overcurrent circuit breaker ETIMAT SM 1p E50 002129205

Overcurrent Circuit Breakers – Reliable Installation Protection

This selective, single-pole ETIMAT SM overcurrent circuit breaker with a rated current of 50A is a key element of every safe and efficient electrical installation. Designed for both professional installers and end-users, it provides effective protection against overloads and short circuits. Mounting on a DIN rail (TH35) guarantees easy and quick installation, and the compact dimensions allow for optimal use of space in the distribution board.

Functionality and Possibilities

The ETIMAT SM circuit breaker is characterized by high selectivity, which means that in the event of a short circuit, only the circuit breaker closest to the fault location will trip, minimizing the scope of outages and facilitating problem location. The tripping characteristic of type E provides a delayed response to short-term current surges – an ideal solution for circuits with devices with high inrush current (e.g., motors). The rated switching capacity of 25kA guarantees safety even in the event of serious disturbances in the network.

• Versatility: The ability to install additional auxiliary contacts, overcurrent and undervoltage releases expands the functionality of the circuit breaker and allows it to be adapted to the specific needs of the installation.
• Readability: The ON/OFF marking on the operating lever and the contact position indicator make it easy to quickly identify the status of the circuit breaker.
• Safety: The ability to seal the lever in the "ON" and "OFF" positions prevents accidental change of the circuit breaker status by unauthorized persons.
• Installation Comfort: Modern mounting method on TH35 rail and the possibility of power supply from below or from above facilitate and speed up installation work.
• Durability and Reliability: Made of high-quality materials, resistant to external factors (IP20 protection degree), ensures long-lasting and trouble-free operation.

Technical Parameters in Practice

The ETIMAT SM circuit breaker is designed in accordance with applicable standards (overvoltage category 4, pollution degree 3) and has a rated insulation voltage Ui 690V and a rated voltage of 400V. The operating frequency is 50Hz. These parameters guarantee its reliable operation in various working conditions and ensure compliance with the requirements of modern electrical installations. Additionally, each circuit breaker is marked with a unique EAN code, which facilitates product identification and traceability.
