Single-pole disconnect switch ITr 1,5-1250 series

DCfor railway applicationsindoor

The single-pole indoor disconnectors mentioned in this list are suitable for railway supply systems. These are switches of category I according to EN 50123-3, operating class VII according to EN 50329, determined for the installation in indoor switchgears. The disconnectors are equipped with an aperture for manual operation by means of an actuating rod. The disconnectors 2000 A can be equipped with a motor actuator. The disconnectors are determined for vertical mounting with a rotary contact downwards. All live parts are made of E-Cu and are hot-galvanised. The cross sections of all live parts are sufficiently sized. Sufficient contact pressure is ensured through stainless pressure springs which also allow a proper operation all over the whole operating life. A higher corrosion capability is reached through hotgalvanization. Each disconnector is fitted with a earthing clamp. The disconnectors 1250 A can be delivered in the following designs: • I - with a flat, straight terminal pad • T - with a flat, T-shaped terminal pad Optionally, it is also possible to equip the disconnectors with position switches for the indication of the switch position (… IS or …TS). The disconnectors 2000 A can be delivered in the following designs: • R - for manual operation • M - for switches with motor actuator The motor actuators can be delivered for rated voltages 24 V, 60 V, 110 V and 220 V DC and also for 230 V AC. This design is equipped with a position switch.
