Overcurrent circuit breaker ETIMAT 10 1p B20 002121717

Overcurrent circuit breaker ETIMAT 10 – reliable installation protection

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 buildings, public facilities and industrial plants, it guarantees safety and continuity of power supply. This model, with a rated current of 20A and characteristic B, is perfect for circuits exposed to short-term current surges, e.g. when starting motors.

Construction and functionality

The ETIMAT 10 circuit breaker is characterized by a compact design – it occupies only one module on a TH35 rail, which facilitates installation and saves space in the switchgear cabinet. Its solid construction and high-quality materials ensure long-lasting and trouble-free operation. The rated short-circuit breaking capacity (Icn) is 10kA at 230V and 400V, and Icu reaches 15kA at 400V and 230V, which confirms its effectiveness in emergency situations. IP20 protection degree protects against accidental contact.

• Versatility: Possibility of power supply from the top and bottom as well as double connection (busbar and wire) facilitate installation in various configurations.
• Additional functions: The circuit breaker can be extended with an auxiliary contact and an overcurrent or undervoltage release, adapting it to specific application needs.
• Contact position indicator: Allows for quick visual control of the circuit breaker status.
• Possibility of sealing: Protects against unauthorized change of the circuit breaker status.
• ON/OFF marking: Clear marking on the actuating lever facilitates operation.
• Product identification: Each circuit breaker has a unique EAN code for easy identification and inventory management.

Technical parameters and compliance with standards

The ETIMAT 10 circuit breaker meets the requirements of IEC/EN 60898-1 and IEC 60947-2 standards, which guarantees its safety and reliability. Adapted to work at ambient temperature from -25°C to +55°C and at frequency 50/60 Hz, it ensures stable operation in various environmental conditions. It accepts solid and stranded wire cross-sections from 1 mm² to 25 mm². The energy limitation class is 3 and the surge category is also 3. The rated voltage is 400V and the insulation voltage Ui is 500V.
