IR3000F line The IR3000F is a range of DC High Speed Circuit Breakers conceived for instalation within DC cubicles for railway infrastructure or in industrial applications. It is specifically designed to protect the downstream power circuits against fault conditions that lead to overcurrents and short circuits. It includes single pole breakers for DC applications with breaking in air, available in two voltage ratings of 900 VDC and 1800 VDC and with thermal current up to 3 kA. The main contacts of IR3000F are held closed by a holding coil or by permanent magnets. The Circuit Breaker is equipped...

IR4000F line The IR4000F is a new range of DC High Speed Circuit Breakers for industrial and DC railway infrastructure applications. Their extremely high breaking performances obtained with a compact design makes them a unique solution in the railway scenario. The IR4000F line is a range of single pole, high speed circuit breakers for DC applications with breaking in air, available in three voltage ratings of 900, 1800 and 3600 VDC and two thermal currents of 3 and 4.5 kA. The main contacts of IR4000F are held closed by a holding coil or permanent magnets. The Circuit Breaker is equipped with...

systems & components for infrastructure SWITCHES DC HIGH SPEED CIRCUIT BREAKERS Its modular design allows to configure the IR4000F in different version by changing only the arc chute: ■ 900 Vdc version (09M) ■ 1800 Vdc version (18M) ■ 3600 Vdc version (36M) This allows to minimize the space occupied within the switchgear in relation to the requested breaking capacity. The breaker is compliant to all the relevant standard for railway infrastructure and industrial solutions (IEC61992; IEEE C37-14; IEEE C37-16 and IEC60947) as well as the newest fire and smoke EN45545. STANDARD CHARACTERISTICS ■...

IR6000F line The IR6000 Series are single pole, magnetic blow out, trip free, air circuit breakers. The closing mechanism is an independent motor operated type. The IR6000 Circuit Breaker is held closed by holding coil or by permanent magnet device and is equipped with a direct acting over-current trip device which may be either unidirectional and bidirectional. The arc chute is made in ceramic material for a longer life and reduced maintenance. The use of arching contacts ensure a long duration in electrical life. The breakers can be used in single voltage or dual voltage applications, where...

LTX line LTX contactors combine the typical robustness of Microelettrica Scientifica products with new and advanced concepts in electric arc breaking. They represent the right solution where high voltage rating, high thermal current and high breaking capacity are required. Specifically, they incorporate the traditional arc-chute design based on ceramic fins with an innovative blow-out system that enhances the contactor’s breaking capacity and guarantees the maximum breaking reliability over the entire range of currents. The opening mechanism enhances the LTX’s breaking and insulating perfomances,...
