The solution for Load break switches sdmat_066_a cat > Main switchboard > Distribution panel > Motor load break unction SIDERMT 4 x 630 External front operation SIDERMT are manually operated 3 or 4 pole load break switches with visible breaking and a remote tripping function. They make and break under load conditions and provide safety isolation for any low voltage circuit. The tripping function assures the following: - protection of persons against insulation faults through combination with toroids and differential relays - protection against overloads through combination with CTs and thermal relays - protection against short circuits with fuses (see "SIDERMT fuse-combination switches" page 36). Strong points > Remote tripping > Safety with visible double breaking > Robustness in harsh conditions Something to think about > SIDERMT combination: Manually operated fuse switches which can be tripped remotely. dvantages Remote tripping Disconnection by a shunt trip device enables the power to the installation to be switched off with a remote pushbutton. unctional diagram or more details, please see the installation instructions supplied with the product. 5 Safety with visible double breaking SIDERMTs are visible double breaking devices (quadruple up to 800 ) providing real and secure display. Robustness in harsh conditions By lowering the current via a limiting resistor, a SIDERMT fitted with an undervoltage coil may be used in continuous processes or exposed to high ambient temperatures. 4 3 sdmat_063_b_2_x_cat 2.
