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.- 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.
