Siemens 3RK1400 Series — siemens Industrial Component
Siemens 3RK1400 Series by siemens encompasses 2 configuration variants for industrial automation, panel building, and machine control applications. This product line is specified by engineers for installations requiring standardized form factors, predictable electrical characteristics, and long-term product availability.
Industrial Applications
- Motor Control Centers (MCC): Motor starting, protection, reversing, and soft starting in automated production lines, conveyor systems, and material handling equipment.
- Power Distribution: Main and feeder circuit protection in low-voltage switchgear and distribution boards for factories, process plants, and commercial buildings.
- Machine Building: Individual machine disconnect, motor overload protection, and auxiliary control circuits in CNC machine tools, packaging machinery, and robotic work cells.
- Building Infrastructure: HVAC fan and pump control, lighting contactors, backup generator changeover, and fire protection system control circuits.
Selection Guidance
When selecting a variant within this series, compare: rated operational current and voltage (matching the load and supply), breaking or switching capacity (adequate for the prospective fault current at the installation point), number of poles or channels, control voltage for coils or actuators, mounting type (DIN rail, panel mount, plug-in or withdrawable), and degree of protection (IP rating for environmental conditions). The manufacturer part number encodes these parameters — providing the complete order code ensures accurate pricing and availability confirmation.
Sourcing and Lead Times
Standard catalog configurations are typically carried in distributor inventory. Special configurations (non-standard coil voltages, custom trip settings, extended temperature ratings) may require 2-8 week manufacturing lead times. For project quantities, contact authorized distributors with the target annual volume and required delivery schedule for volume pricing.
