SIDERMAT 4 x 630 A External Front OperationFunction
SIDERMAT are manually operated 3 or 4 pole load break switches with visible breaking and a remote tripping function. It’s make and break under load conditions and provide safety isolation for any low voltage circuit.

The tripping function is used to provide the following functions:

• personal protection against insulation faults when utilised in combination with toroids and differential relays.
• protection against overloads when utilised in combination with CTs and thermal relays.

AdvantagesRemote trippingSafety thanks to visible double breaking

• Disconnection by a shunt trip device enables the power to the installation to be switched off with a remote pushbutton.

• SIDERMATs are double breaking devices with visible contacts which provide a clear and secure display of the contact positions.

Utilisation in harsh operating conditions

• By lowering the current via a limiting resistor, a SIDERMAT fitted with an undervoltage coil may be used in continuous processes or exposed to high ambient temperatures.
