Siemens 3RH Series Auxiliary Contact, 6A Contact Current, 250V Contact Voltage - 3RH1921-1EA20
This auxiliary contact provides lateral Snap-on switching for integration with contactors in automation and electrical installations. Designed for use alongside compatible contactor families, it offers two normally open switching elements and screw-type terminations to facilitate straightforward control and signalling within industrial control panels.
Features & Benefits
• 2NO instantaneous contacts deliver clear on‑state signalling
• Screw terminals accept 0.5 to 2.5 mm² conductors for secure wiring
• Operational current up to 10A supports varied control circuits
• Rated insulation voltage Ui 500V enables higher‑voltage isolation
• Mechanical endurance 10 million cycles reduces maintenance intervals
• Operates between -25°C to 60°C for broad environmental use
• Screw terminals accept 0.5 to 2.5 mm² conductors for secure wiring
• Operational current up to 10A supports varied control circuits
• Rated insulation voltage Ui 500V enables higher‑voltage isolation
• Mechanical endurance 10 million cycles reduces maintenance intervals
• Operates between -25°C to 60°C for broad environmental use
**Applications**
• Suitable for lateral mounting on industrial contactors
• Used with 3RT1‑type contactors in motor control systems
• Can be used for auxiliary signalling in control panels
• Ideal for replacing or extending contactor auxiliary functions
• Used with 3RT1‑type contactors in motor control systems
• Can be used for auxiliary signalling in control panels
• Ideal for replacing or extending contactor auxiliary functions
What Terminal types are provided for electrical connection?
Connections are via screw‑type terminals capable of solid, stranded or finely stranded conductors with ferrule/crimp end processing within the specified cross‑section range.
How does the product behave under AC control‑duty conditions?
Under AC‑15 and AC‑12 utilisation categories it carries defined currents such as 6A at 125V/250V and 10A at 24V/230V depending on the category and voltage.
Can multiple current paths be used in series and what are the limits?
Yes
ratings are specified for two or three current paths in series with decreasing allowable currents as voltage increases, for example 10A at 24V and lower currents at higher voltages.
