Manual Motor Starter 6.3 A 690 V AC
The SIEMENS 3RV20111GA10 is a three-pole manual motor starter rated for 6.3 A and 690 V AC. It provides overload and short-circuit protection for single motors in industrial machinery and automation panels. The selector-switch operator allows direct local control without a separate contactor. It suits maintenance engineers and panel builders who need compact, DIN-rail mountable motor protection.
Three-phase ratings and voltage limits
The starter covers three-phase motors up to 1 hp at 208 V AC, 1 1/2 hp at 240 V AC, 3 hp at 480 V AC and 5 hp at 600 V AC. Single-phase ratings are 1/4 hp at 120 V AC and 1/2 hp at 240 V AC. The maximum operational voltage is 690 V AC, so it cannot be applied on higher-voltage networks. The fixed overload relay setting of 6.3 A limits the maximum full-load current it can protect.
Capacity headroom and where it stops
The 6.3 A setting comfortably handles small pumps, fans and conveyors within the listed horsepower bands. It runs out when motor full-load current exceeds 6.3 A or when the application demands a higher horsepower rating than those specified for each voltage. Buyers needing to protect larger motors or adjustable overload settings must select a different starter.

Questions about this item
Which horsepower rating should I use for a 240 V three-phase motor?
The starter is rated for 1 1/2 hp at 240 V AC three-phase and 1/2 hp at 240 V AC single-phase; match the rating to your motor wiring.
What does the 6.3 A current rating mean for daily operation?
It sets the maximum overload relay trip point at 6.3 A, so the motor full-load current must not exceed this value.
What does the 690 V AC maximum voltage cap in practice?
It limits the starter to supply systems up to 690 V AC; do not apply higher line voltages.
