SAFETY RELAY 3RV2011-1AA10

Description

The 3RV2011-1AA10 is a Siemens SIRIUS motor protection circuit breaker (MPCB) designed for protecting small motors and electrical loads against overload, short-circuit, and phase failure conditions. It is part of the 3RV2 series (Size S00) and is widely used in industrial control panels, motor starter circuits, and automation systems.

Although often searched as a “safety relay,” this device is not a safety relay in the functional safety (E-Stop/safety controller) sense. Instead, it is a motor protection breaker with integrated thermal and magnetic trip functions.

Key Features

• Motor protection circuit breaker (MPCB), not a safety relay
• Protects against overload, short circuit, and phase loss
• Adjustable thermal overload range: 1.1 – 1.6 A

• Compact Size S00 design for control panels
• Rotary knob for easy current setting
• High breaking capacity for industrial protection
• Screw-type terminal connections
• Suitable for motor starter combinations (with contactors)
• IEC / UL approved for industrial applications
