ETI ETIMAT 10 Circuit Breaker 1P 125A B 15kA (2121733)

The ETIMAT 10 series circuit breaker from ETI is designed for protection of electrical circuits against overload and short circuit. It is intended for installation in distribution boards of residential, commercial, and industrial facilities where automatic disconnection of a line is required in the event of an аварійний режим and where continuity of the electrical network must be maintained as far as possible. The single-pole design makes this device suitable for circuits that require interruption of one conductor. This model is rated for 125 A and operates in AC networks with a nominal voltage of 240/415 V. It is compatible with mains frequency of 50 Hz or 60 Hz, which allows use in different electrical systems. The B tripping characteristic means the breaker responds to overloads and short circuits in circuits with low inrush currents, so it is appropriate for lines with primarily resistive or moderately inductive loads. The breaking capacity of 15 kA indicates the ability to safely interrupt high short-circuit currents, which is an important parameter for protective devices used in networks with elevated fault current levels. The rated impulse withstand voltage Uimp is 4 kV, confirming resistance to short-duration overvoltage. For conductor connection, a rated cross-section of 25–50 mm² is specified, so the device is suitable for power lines within this conductor range. The breaker complies with IEC/EN 60947-2, the standard governing low-voltage switchgear and controlgear. This confirms that the device meets the requirements for protective and switching equipment used in electrical installations. With its rated current, tripping curve, breaking capacity, voltage range, and conductor cross-section compatibility, the ETIMAT 10 is intended for use in power circuits where overload and short-circuit protection must be provided under AC 240/415 V conditions.
