Installation Materials

SIGMA Moulded Case Circuit Breakers are produced as 1, 3 and 4 poles from 25A up to 1600A according to IEC /EN 60947-2 and CE standards and used for protecting the circuits which have different characteristics like cable, motors, lighting, and generators.

Sigma thermal O/L relays are designed to meet the special protective needs of motor control circuits. Overload relays allow harmless temporary overloads (such as motor starting) Without disrupting the circuit and they will trip and open a circuit if current is high enough to cause motor damage over a period of time. They can be reset once the overload is removed. The thermal overload relays are used With the Sigma AC power contactors to prevent short circuits and current-overload.
