AC-15 is the switching category for solenoid loads — think valve coils, contactor coils, electromagnetic brakes — where the inrush can hit several times the holding current. The 48-460 VAC load voltage range covers common European and North American control voltages, and the 4-30 VDC control input lets a PLC or safety relay fire it directly without an interposing relay. This is a DIN-rail mount part, sized for a standard enclosure. The packaging dimensions of 105 x 27 x 122 mm give you the physical envelope — 27 mm wide, so it takes one standard modular device slot. When you're laying out a panel with a mix of SIRIUS contactors and overloads, the 3RF33 shares the same footprint as the 3RT2 electromechanical contactors, which simplifies the gland plate layout and wireway planning. Screw terminals accept the wire sizes typical for a 15 A control circuit — no special crimping or ferrule tool required beyond what the panel shop already carries. The control supply is 4-30 VDC, which is wide enough to tolerate a sagging 24 V bus in a cabinet with several loads switching simultaneously. The lifecycle status is current and active — this is not a phase-out or NRND line. RoHS compliance is confirmed effective 15 January 2024, and the REACH Article 33 disclosure notes lead (CAS 7439-92-1) above 0.1% w/w, which is a standard declaration for certain lead-bearing alloys in the terminal or internal construction. No UL or CSA listing is stated in the available documentation, so verify with the factory if your site requires a specific agency mark.","metaTitle":"Siemens 3RF3330-1BA44 SIRIUS Solid-State Contactor, 15 A, 48","metaDescription":"Siemens 3RF3330-1BA44 SIRIUS 3RF33 solid-state contactor, 1-pole, 15 A AC-15 at 40 °C, 48-460 VAC load, 4-30 VDC control.
