Siemens 3RV2011-4AA10 Molded Case Circuit Breaker

Siemens 3RV2011-4AA10 Molded Case Circuit Breaker is a Sirius 3RV2 motor-protection switch in the compact S00 size, designed for panel-mounted motor circuits up to 400 V AC. It provides thermal-magnetic protection with Class 10 trip characteristics and offers an A-release setting of 11–16 A and an N-release rated at 208 A for short-circuit protection, enabling coordinated tripping with nearby devices in motor starter assemblies. The device uses screw terminals for secure wiring and delivers standard switching capacity within the 3RV2 family, making it suitable for protecting small to mid-size motors in industrial control panels and machine systems. This model's label, 3RV2011-4AA10, corresponds to a size S00 frame and a motor-protection designation, ensuring reliable protection against overloads and short circuits while preserving supply continuity for running equipment. Its compact form factor, combined with Siemens' Sirius protection technology, supports convenient integration into existing Sirius 3RV2 protection schemes and DIN-rail mounted panels where space is at a premium.
