BREMAS Line disconnect switches The DS disconnect switches series are characterized by high performance and are suitable for installation in distribution circuits and power engines, in distribution boards or directly on the machine, with alternate current rating from 20 up to 100A. Dimensions The DS series has the most compact dimensions on the market that provide installation in reduced spaces also thanks to the many handles with IP66 protection degree.

Fixing types It is possible to choose between different fixing types according to the needs: Rear mounting 2 holes with vertical interaxis 28mm (1.10”) 4 holes with interaxis 36mm / 48mm (1.42”/1.89”) Single hole ø 22 mm (0.87”) holes with fixing nut Base mounting with control shaft Snap mount on DIN rail 2 screws Plate fixed on panel with 2 or 4 screws or with single hole Ø 22mm (0.87”) with fixing nut Base mounting direct operation (with handle) Base mounting for panel board - DDN Base mounting version DDN version

BREMAS Line disconnect switches Adjustable depth for the control shaft The base mounting version of the DS includes an ergonomic handle for direct command of the switch; the handle also incorporates a housing for the shaft with a fixing screw. The height of the shaft can be adjusted within an excursion of 20mm, therefore the need of cutting the shaft can be reduced. Base mounting switches are provided with 175mm. shaft. In the 20-32-40A base mounting version, the shaft insertion dimension in the housing has a tolerance of about 20mm; this makes it possible to reduce the need to cut the...

The terminals access depending on the fixing option: Rear mounting: rear access to terminals. Base mounting: front access to terminals. Rear mounting version Base mounting version And also: The clamps are provided in open position and equipped with captive plus-minus screws. Protection against direct contacts assured even when the panel is opened. The DS disconnect switches series can be equipped with 2 additional poles and/or 2 auxiliary contact (max 1 per side).

BREMAS Line disconnect switches Plates and knobs for every application A complete IP66 range All the most common plates and knobs are available, for base and rear mounting, with or without padlocking. For all these plates and knobs the IP66 degree of protection is guaranteed, allowing the installation even in difficult environments. The base mounting plates and knobs are provided with door interlock mechanism in “I/ON” position to avoid door opening when the board is connected to the supply.
