Description

This Acti9 NG125NA is a low voltage switch disconnector with free tripping for making and breaking under load. It has 4P with 4 protected poles. Its rated current is 1250A at 500VAC. It can be mounted on DIN rail for modular installation. Its width is 12 modules of 9mm. The degree of protection is IK05 and IP20 becoming IP40 once in modular enclosure. It is especially suitable for the modular enclosure incoming feeder with remote breaking (e.g. emergency cutoff). its service life is improved due to a good overvoltage withstand capacity, high limitation performances and a fast closure independent of the speed of actuation of the toggle. A test button allows to check the satisfactory operation of the tripping mechanism. It has a circuit breaker tripped indicator and the central manual control has 3 positions (ON, tripped on fault, open). The presence of the green strip guarantees physical opening of the contacts and allows operations to be performed on the downstream circuit in complete safety.
