Auxiliary switch, electronically delayed, ON-delay relay 1 NO contact – 3RA28131AW10

Electrically time-delayed auxiliary switch, on-delay, relay: 1 C.O., time range 0.05-100 s, AC/DC 24-240 V, 50/60 Hz, varistor integrated for damping contactor coils, screw terminal, snap-on front mounting to contactors 3RT20 and auxiliary contactors 3RH2 Electrically delayed auxiliary switch SIRIUS 3RA28 for time-delayed switching of subsequent circuits for mounting on contactors 3RT2 and auxiliary contactors 3RH2. The electrically delayed auxiliary switches offer high setting accuracy through switchable time ranges and feature integrated electrical interlock and a factory-integrated varistor (protective circuit). Simple and tool-free snap-on mounting enables control-independent time functions to be implemented without additional wiring. This avoids wiring errors and reduces testing costs. Front mounting to the devices saves space on the DIN rail. Thanks to international approvals (e.g. IEC, CCC, UL/CSA), the devices can be used worldwide. The electrically delayed auxiliary switches are available for contactors 3RT2 and auxiliary contactors 3RH2 in sizes S00 to S3. Available with flexible wide voltage range AC/DC 24-240 V, selectable outputs 1 NO + 1 NC or 1 C.O. and with screw or spring-type terminal technology. Wiring kits and a sealable cover are available for the electrically delayed auxiliary switches. SIRIUS relays - a program for all applications.
