The Siemens 3RH1911-1FA11 is an auxiliary switch block from the SIRIUS product line, suitable for integration with contactor relays and power contactors. This unit provides one normally open (NO) and one normally closed (NC) contact configuration.
Key electrical specifications include a rated insulation voltage of 690V with a pollution degree of 3 and an impulse voltage resistance of 6kV. The operating current capabilities vary by load type, with AC-12 at 24V rated for a maximum of 10A, and AC-15 at 230V rated for 6A. DC operating currents are also detailed for various voltage levels and series configurations.
Mechanically, the switch block is designed for snap-on mounting and has dimensions of 36.5mm width, 37.5mm height, and 41.5mm depth. It utilizes screw-type terminals for auxiliary and control current circuits, supporting finely stranded conductors with conductor end processing from 0.5 to 2.5 mm² and AWG conductors from 14 to 20.
Environmental considerations include an operating temperature range of -25°C to +60°C and a storage temperature range of -55°C to +80°C. The front protection class is rated at IP20. The component boasts a typical mechanical operating life of 10,000,000 cycles and an electrical operating life of 200,000 cycles at AC-15, 230V.
