for power distribution from 125 to 3150 A with visible breaking

SIDER units are manually operated 3 or 4-pole load break switches. They make and break under load conditions and provide safe isolation for any low voltage circuit.


In public distribution, SIDER load break switches are frequently used at the level of section incomers in LV substations (reduced size urban switchboards, etc).


Safety thanks to visible breaking

Visible breaking and positive break indication ensure safe switching. The user can assess the condition of the device either during a preventive check or before an operation.
SIDER load break switches are most suitable for use in safety enclosures in explosive atmospheres (zones 21 and 22). The addition of a mechanical flag indicator, directly connected to the device's breaking system, provides reliable position information on the front of the enclosure.
