Product Description

Product Description

Load break switches are devices used to open an electrical circuit by isolating the source from the consumer. Whether they are manual, motorised or with a trip function, these devices ensure the on-load making, breaking and safety disconnection of low-voltage electrical circuits. Easy to assemble and easy to use, they are suitable for structures evolving in the industrial sector, public distribution, as well as emergency switching, distribution panels and motor feeders.

Modular device

• EHD DC load break switches  are devices which are DIN rail or backplate mountable and can be integrated into a modular panel with a 45 mm front cut-out.
• Patented switching technology
• EHD DC load break switches with benefit from proven breaking technology based on a system of double break contacts with arc extinguishing chambers.

Product Benefits

Easy to install

• Wiring: Switch is non-polarized, all types of wiring and connections are possible.
• Auxiliary contacts easily mounted.
• The operating mechanism can be placed to meet the installation requirements.

Safe reliable operation

• Reliable position indicator through visible windows.
• The opening and closing of the switch is fully independent from the speed of operation, ensuring safe operation under all conditions.
• High temperature withstand: no derating up to 70°C.
• Ambient Temperature: -40°C to +70°C.

Designed for harsh environments

• Vibration testing (from 13.2 to 100 Hz at 0.7 g).
• Shock testing (15 g during three cycles).
• Humid temperature testing (2 cycles, 55°C/131F with 95% humidity level).
• Salt mist testing(3 cycles with humidity storage, 40°C/104F, 93% humidity after each cycle).
