ETI ETIMAT 10 1-pole 100A C 20kA circuit breaker (2131732)

The ETIMAT 10 circuit breaker by ETI is intended for protecting electrical circuits against overload and short circuit in distribution boards used in residential, commercial, and industrial electrical systems. It provides both switching and protective disconnection of the line under fault conditions, making it suitable for circuits where safe interruption of the supply is required. With one pole, the device is used in single-phase circuits or in individual lines that need dedicated protection. The rated current is 100 A, so the breaker is designed for circuits with elevated load levels. The C tripping characteristic makes it suitable for circuits with moderate inrush currents, for example where connected equipment may draw a short-term current higher than the normal operating value during start-up. This characteristic helps maintain stable operation while still providing protection against overload and short circuit. The breaking capacity of 20 kA indicates the ability to disconnect high short-circuit currents, which is important in networks with significant prospective fault current. The device is intended for AC networks and operates at a rated voltage of 240/415 V AC with a rated frequency of 50/60 Hz, which matches common power supply parameters. The rated impulse withstand voltage Uimp of 4 kV reflects resistance to short-term overvoltages. For conductor connection, the nominal cross-section range is 25–50 mm², allowing use with appropriately sized cables or wires in power circuits. This automatic circuit breaker complies with IEC/EN 60898-1 and IEC 60947-2 standards, which define the requirements for performance and application of protective switching devices. As part of the ETIMAT 10 series, it is a practical solution for protecting feeder and power lines where a 100 A rating, high breaking capacity, and compatibility with standard AC network parameters are required.
