At a glance This product overview shows the essential technical data for our products. The complete and detailed technical data sheets can be found on our website under www.e-t-a.de/en. Side-by-side mounting When several devices are mounted together, there may be a mutual thermal influence when they carry rated load. This influence is similar to an increased ambient temperature, depending on the current rating, the number of breakers, the distance between them and the ventilation. When mounted side-by-side, the breakers can only carry up to 80 % of their rated current or a higher rating...

Protecting – Switching – Monitoring current Typical time/current characteristic curves magnetic (MO) (no delay) (delayed magnetic curves available) Magnetic circuit breakers (MO) Circuit breakers with a magnetic trip characteristic trip extremely fast. In the event of a short circuit the faulty circuit will be interrupted nearly without delay. The magnetic system of the breaker is the sole tripping element. As tripping depends on the time curve of the magnetic force and thus also on the magnetic field, the trip limit is influenced by the shape of the current characteristic (AC/DC). Magnetic...

Electronic overcurrent protection With electronic overcurrent protection the load current is measured with an integral current sensor. In the event of an overload the circuit will be interrupted after approx. 5 sec even with cable attenuation. In the event of a short circuit in the load circuit, the overcurrent will be limited electrically and then disconnected. This will prevent a voltage dip in the power supply. An electronic circuit breaker will also physically isolate the load circuit in the event of an overcurrent. Electronic protection is suitable for DC 24 V circuits in automation...

Circuit breakers for equipment protection Thermal circuit breakers Magnetic and hydraulic-magnetic circuit breakers Applications: Circuit breakers with thermal trip ensure the best possible overload protection for electric motors, transformers, magnetic valves, on-board electrical systems and low voltage lines. Applications: Magnetic and hydraulic-magnetic circuit breakers are ideally suited to the protection of printed circuit boards and semi- conductors against overcurrent and short circuit and to the use in the telecommunications industry. Engineering: The trip time of thermal circuit...

A modern classic for a wealth of applications The trip time of thermal circuit breakers depends on the height and duration of the overload current. With higher current ratings, the bimetal or hot wire is heated up until the defined trip time is reached. Circuit breakers with thermal trip characteristics are suitable for protection of loads such as motors, transformers, magnetic valves, low voltage lines and on-board electrical systems. Characteristic features • A powerful snap action mechanism ensures that closing speed of the contacts is independent from the actuating speed. This increases...
