Strong Points


COMBINED SIDERMAT DIN are manually operated 3 or 4-pole load break switches with a remote tripping function.
They provide load operation, safety disconnection and protection against overloads and short-circuits in any low voltage electrical circuit. They can ensure the automatic opening of the circuit together with:
- fuse blown detection system (see DDMM or FMD),
- thermal relay,
- differential relay (see RESYS),
- other safety devices.

Conformity to standards

- IEC 60947-3
- IEC 60269-1
- IEC 60269-2


Automatic tripping

COMBINED SIDERMAT DIN is the only fuse combination switch that allows automatic remote opening by means of a coil associated with an external device.

Optimum safety

Visible double breaking indication by phase (up and downstream from the fuse) to show the actual position of contacts and keep personnel and equipment protected from overcurrent.

High breaking capacity

High breaking capacity fuses (100  kA rms) provide protection from overloads and short circuits.
