3RV2031-4PA10 SIEMENS PLC Programmable Logic Controller 24 V DC 60V 2A
3RV2031-4PA10 Description:The 3RV2031-4PA10 is a high-performance Motor Protection Circuit Breaker (MPCB) from Siemens' SIRIUS 3RV series. Designed for reliable protection of motors, cables, and equipment in industrial power distribution systems, this device combines the functions of a circuit breaker, overload relay, and short-circuit protector in a single, compact unit. It features adjustable overload and short-circuit trip settings, ensuring precise coordination with motor characteristics and providing comprehensive protection against overloads, phase loss, and short circuits. With its easy installation, clear status indication, and compatibility with Siemens control gear, it is a robust solution for motor feeder protection in harsh industrial environments.
3RV2031-4PA10 Features:
3-in-1 Protection: Integrates motor overload protection, short-circuit protection (magnetic trip), and isolating function in one device, simplifying panel design and reducing component count.
Adjustable Trip Settings: Fine-tunable overload current setting (Ir) and selectable magnetic short-circuit trip class (Class 10) allow precise matching to motor specifications and starting characteristics.
Clear Visual Indication: Integrated status indicators (green/red) and a trip flag provide immediate visual feedback on operational state and fault conditions (overload or short-circuit trip).
High Breaking Capacity: Offers a high fault current breaking capacity, ensuring safe interruption of short-circuit currents and protecting downstream equipment.
Space-Saving Design: Compact width allows for high-density mounting in control panels and enclosures, saving valuable installation space.
Excellent Connectivity: Equipped with screw-type terminals (front accessible) and is fully compatible with Siemens SIRIUS contactors for building coordinated motor starters (e.g., with 3RT contactors).
3RV2031-4PA10 Materials & Applications:
Housing: Self-extinguishing, high-strength thermoplastic material (UL 94 V0 rated) with high dielectric strength and temperature resistance.
Current Paths & Contacts: Silver-plated copper alloy for low contact resistance, high conductivity, and durability.
Trip Unit: Bimetallic strip for thermal overload protection; solenoid for magnetic short-circuit protection.
Terminals: Robust screw-type terminals with captive screws, designed for reliable cable connections.
Applications: Primarily used for the protection and control of three-phase AC motors in industrial machinery, conveyor systems, pumps, fans, compressors, HVAC systems, and manufacturing automation panels.
