KS series control boxes – reliability and functionality in every circuit

KS type control boxes, manufactured by Promet, are versatile solutions designed to control various devices – from cranes and hoists, to machine tools and remote control machines. A wide range of applications and a solid construction make them ideal for both professional installers and end users. These boxes allow for safe and efficient management of electrical circuits with a voltage of up to 400V AC and 220V DC.

Construction and user features

The housing of the boxes is made of high-impact plastic, which ensures mechanical and dielectric strength. This makes the boxes resistant to damage and provides long-term reliability. The IP65 protection rating guarantees protection against dust and water jets, allowing installation in harsh industrial conditions. The segmented design allows for flexible adjustment of the number of control elements to individual application needs.

Promet control boxes are characterized by high quality workmanship and compliance with PN-EN 60957-5-1 standard. This ensures safe use and reliable operation in demanding industrial environments. Additionally, the possibility of choosing different climatic versions (standard or special) allows adaptation of the boxes to specific working conditions.

Technical specifications and application

KS series control boxes offer a range of technical parameters, tailored to various applications. The rated insulation voltage is 400V (50-60Hz), the rated switching voltage is 400V (50-60Hz) / 220V DC, and the rated impulse withstand voltage is 2.5 kV. The thermal current is 10A, and the switching current (AC4) is 2.5A at Ue = 400V, (AC15) is 1A at Ue = 400V and (DC13) is 0.16A at Ue = 220V. The cross-section of connection wires can accommodate a cable/wire with a diameter of 0.5 – 1 mm², and the diameter of the connection cable should be from 10 to 30 mm.

Various types of boxes are available – from one-, two-, three-, to six-element – allowing for precise adaptation to a specific application. A wide selection of control elements (e.g. start/stop buttons, emergency stop buttons, indicator lights) allows you to create a complete control system tailored to individual needs. The KS 3 box, with catalog number W0-KS3-1-2-058S.35.45, has 4 control positions. It is made of yellow plastic and has a protection rating of IP65.
