Длинное описание: UA16..RA 3-pole contactors for capacitor switching, can be used in installations in which the peak current far exceeds 100 times nominal rms current. The contactors are delivered complete with their damping resistors and must be used without additional inductances (see table below). The capacitors must be discharged (maximum residual voltage at terminals ≤ 50 V) before being re-energized when the contactors are making. Their electrical durability is 250 000 operating cycles for Ue < 500 V and 100 000 operating cycles for 500 V ≤ Ue ≤ 690 V. The UA..RA contactors are fitted with a special front mounted block, which ensures the serial insertion of 3 damping resistors into the circuit to limit the current peak on energization of the capacitor bank. Their connection also ensures capacitor precharging in order to limit the second current peak occurring upon making of the main poles. The insertion of resistors allows to damp the highest current peak of the capacitor when switching on, whatever its level. The UA..RA series 3-pole contactors are of the block type design. - Main poles and auxiliary contacts: 3 main poles, 1 built-in auxiliary contact - Control circuit: AC operated with laminated magnet circuit - Accessories: a wide range of accessories is available.

Описание в каталоге: UA16-30-10RA 500V 50Hz / 600V 60Hz Contactor
Длинное описание: UA16..RA 3-pole contactors for capacitor switching, can be used in installations in which the peak current far exceeds 100 times nominal rms current. The contactors are delivered complete with their damping resistors and must be used without additional inductances (see table below). The capacitors must be discharged (maximum residual voltage at terminals ≤ 50 V) before being re-energized when the contactors are making. Their electrical durability is 250 000 operating cycles for Ue < 500 V and 100 000 operating cycles for 500 V ≤ Ue ≤ 690 V. The UA..RA contactors are fitted with a special front mounted block, which ensures the serial insertion of 3 damping resistors into the circuit to limit the current peak on energization of the capacitor bank. Their connection also ensures capacitor precharging in order to limit the second current peak occurring upon making of the main poles. The insertion of resistors allows to damp the highest current peak of the capacitor when switching on, whatever its level. The UA..RA series 3-pole contactors are of the block type design. - Main poles and auxiliary contacts: 3 main poles, 1 built-in auxiliary contact - Control circuit: AC operated with laminated magnet circuit - Accessories: a wide range of accessories is available.

Выдерживают неограниченный пиковый ток
Коммутация конденсаторов отличается очень высокими пиковыми значениями тока при включении питания конденсаторов. Контакторы UA..RA имеют встроенный гасящий резистором, позволяющий справляться с любыми пиковыми значениями тока.
Преимущества
- Самый широкий на рынке ассортимент контакторов
- Надежность в областях применения, где требуется коммутация конденсаторов
- Простой выбор благодаря программному обеспечению CAPCAL
Возможности
- Контакторы UA..RA с гасящими резисторами используются, когда пиковое значение тока намного превышает 100-кратное среднеквадратичное значение номинального тока
- Контакторы UA используются, когда пиковое значение тока меньше или равно 100-кратному увеличению номинального среднеквадратичного значения тока
- Благодаря технологии AF и электронной катушке доступны контакторы UAF..RA с широким диапазоном управляющего напряжения.
