Relè di sovraccarico Siemens, 1NC + 1NO, carico FLC 0.32 → 1.25 A, 1.25 A

The Siemens SIRIUS 3RB series is a solid-state overload relay for inverse-time delayed protection of loads with normal and heavy starting against excessive temperature rises due to overload, phase unbalance or phase failure which has a current rating up to 1.2 A. It has manual or automatic reset switch functionality. It has a size S0. It can be mounted with contactor mounting. The type of electrical connection for main circuit and for auxiliary circuit is through screw-type terminal. Due to the wide current setting ranges and various tripping characteristics, complete series of motors are covered with just a few types. It has low heat loss which makes it energy-efficient and help to reduce the temperature rise in the control cabinet.

Ambient operating temperature is -25 to +60 °C
Operating frequency is 50 to 60 Hz
Trip class is CLASS 10E
