Electronic time-delayed auxiliary switch, off-delayed with control signal relay 1 NC + 1 NO AC/DC 24...240 V Time range 0.05...100 s, can be snapped on at the front for 3RT2 S00-S3 contactors and 3RH2 S00 contactor relays, spring-loaded connection, varistor for damping the contactor coils integrated Electronically delayed auxiliary switch SIRIUS 3RA28 for the time-delayed switching of subsequent circuits for mounting on 3RT2 contactors and 3RH2 contactor relays. The electronically delayed auxiliary switches offer a high level of setting accuracy thanks to switchable time ranges and have an integrated electrical interlock and a factory-integrated varistor (protective circuit). The simple and tool-free plugging enables the implementation of control-independent time functions without additional wiring. This avoids wiring errors and reduces testing costs. By attaching the devices to the front, you save space on the top hat rail. The devices can be used worldwide thanks to international approvals (e.g. IEC, CCC, UL/CSA).The electronically delayed auxiliary switches are available for 3RT2 contactors and 3RH2 auxiliary switches in sizes S00 to S3. Available with a flexible wide voltage range AC/DC 24-240 V, selectable outputs 1 NO + 1 NC or 1 W and with screw or spring-loaded connection technology.Wiring kits and a sealable cover are available for the electronically delayed auxiliary switches.SIRIUS relays - a program for all cases.
