nstallation Contactors HS 230 V~/50 Hz and 24 V~/50 Hz Function: Installation contactors are electromagnetic actuated switches. When a control current is applied across the trip coil, the resulting magnetic attraction closes a main circuit. The energized status is maintained for as long as the control current is flowing. Characteristics: Installation contactors are especially suitable for very frequent switching of high currents. The suitability of contactors for disconnecting is subject to qualification; they must be safeguarded against overloads and short-circuits by series-connected protective devices. The HS model range meets the requirements of utilization categories AC1, AC3 and, conditionally, AC7b. The utilization category indicates the frequency of switching and the current load capacity of the contact material (see DIN VDE 0660 Part 102 and EN 60947-4-1). The trip coil of the HS model range is extremely low-noise and suitable for continuous operation (100% duty cycle). Mounting method: Snap-on fastening on DIN-rail to EN 50022 Applications: Installation contactors can be used for various applications in domestic and utility buildings as well as industrial plants. They take over the task of switching · incandescent lamps · fluorescent lamps · transformers for halogen low-voltage lamps · high-pressure mercury vapour lamps (HQL, HPL) · metal halide lamps (HQI, HPI) · low- and high-pressure sodium vapour lamps · storage heaters · drives (motors) Accessories: · HSH 11 auxiliary switch for HS 20 (4-pole)/ HS 25 / HS 40 / HS 63 · HSP 25 sealing cover for HS 20 (4-pole) / HS 25 · HSP 40/63 sealing cover for HS 40 / HS 63
