Overcurrent circuit breaker ETIMAT 10 1p B40 002121720

Overcurrent circuit breaker – reliable protection for installations

The ETIMAT 10 overcurrent circuit breaker is a key element of every electrical installation, providing effective protection against the effects of overloads and short circuits. Designed for use in residential, public and industrial facilities, it guarantees safety and long-term reliability. The design and parameters of this circuit breaker make it a suitable solution for both professional installers and end users.

Functionality and technical parameters

The ETIMAT 10 circuit breaker is characterized by a rated current of 40A and a B characteristic, which means it reacts quickly to current increases but tolerates short-term load surges – an ideal solution for circuits with receivers with high starting current, e.g. motors. The rated short-circuit breaking capacity (Icu) is 15kA at 230V and 400V, and the Icn capacity according to EN 60898 is 10kA at both voltages. This ensures effective disconnection of the circuit in the event of a failure.

The circuit breaker design is designed for easy mounting on a TH35 rail. Compact dimensions (1 module width) allow for optimal use of space in the distribution board. In addition, the possibility of power supply from the top and bottom and double connection (busbar and cable) increase installation flexibility. The cross-section of the connected multi-wire and solid-core cable is from 1 to 25 mm², which allows adaptation to different types of cables.

User comfort and additional functions

The ETIMAT 10 circuit breaker offers a range of features that increase user comfort and safety:

• Possibility of sealing: The lever can be secured against accidental setting to the "On" or "Off" position.
• Additional equipment: The possibility of mounting auxiliary contacts, overcurrent and undervoltage releases expands the functionality of the circuit breaker.
• Contact position indicator: Allows for quick visual control of the circuit breaker status.
• ON/OFF marking: Clear marking on the lever makes operation easier.
• Possibility of circuit labeling: Allows easy identification of the protected circuit.
• Effective touch protection: Ensures user safety.
• EAN codes: Each circuit breaker has an individual EAN code to facilitate identification and inventory management.
• Wide operating temperature range: The circuit breaker retains its properties in the temperature range from -25°C to +55°C.

Thanks to these features, the ETIMAT 10 circuit breaker is a comprehensive solution for demanding electrical installations, combining reliability, safety and ease of use. It meets the requirements of IEC/EN 60898-1 and IEC 60947-2, which confirms its high quality and compliance with applicable standards.
