Description

Product Overview

The EATON XV-303-15-C00-A00-1B​ is a highly specific and configurable Component Module​ from Eaton’s motor control and power distribution portfolio, most likely a contactor​ or relay base unit. The extended alphanumeric code indicates a precise configuration within a modular system. The breakdown suggests: XV​ likely denotes the product family; 303​ specifies the series or frame size; 15​ indicates the current rating​ (likely 15 Amperes); C00, A00, and 1B​ are detailed configuration codes defining aspects such as coil voltage, number/type of auxiliary contacts, mounting style, and terminal types. This module is not a complete starter, but rather a core switching component​ designed to be part of a larger, modular assembly. Its primary function is to provide the electromagnetic switching mechanism for controlling electrical loads (such as motors, heaters, or lighting) when combined with other modules like overload relays and enclosures.
The value of the EATON XV-303-15-C00-A00-1B​ lies in its modularity, flexibility, and precision. In Eaton’s modular contactor systems (such as the DIL​ or PKZ​ series families), users can build a custom motor starter or load controller by selecting a base contactor module with the exact specifications needed. This particular module, with its 15A rating and specific configuration codes, represents a tailored building block. It allows engineers to precisely match the electrical characteristics (coil voltage, contact arrangement) and mechanical features (mounting, terminals) to the exact application requirements, optimizing cost and performance. For panel builders and system integrators, this modular approach simplifies inventory management (stocking standard components), reduces lead times for custom configurations, and enables easy field modifications or upgrades by swapping or adding modules.

Key Features and Advantages

EATON XV-303-15-C00-A00-1B​ excels as a precision-engineered, modular building block. Its primary advantage is configuration flexibility. By selecting this specific combination of codes, a user obtains a contactor perfectly matched to their control voltage (C00), required signaling contacts (A00), and installation method (1B). This eliminates over-specification and waste. The modular design allows the base contactor to be easily combined with a matching thermal or electronic overload relay, man-machine interface modules, and enclosures​ to form a complete motor starter or load switching center.
Robust construction and reliable performance​ are inherent. Designed to IEC standards, it offers high electrical and mechanical endurance, ensuring long service life even in demanding switching applications. The clear marking of terminals and the snap-together or screw-together design​ of the modular system makes assembly quick and error-free. For maintenance, individual components (like the coil or auxiliary contact block) can often be replaced without replacing the entire unit, reducing downtime and spare parts cost.
Simplified logistics and inventory control​ are significant system-level benefits. Panel builders can stock a range of standard base modules, coils, and accessories, assembling custom configurations on demand rather than stocking countless pre-assembled, fixed-configuration units. This modularity also future-proofs installations; if a control voltage changes, only the coil module might need replacement. In summary, the XV-303-15-C00-A00-1B​ represents the core of a flexible, reliable, and economical motor control strategy, empowering users to build exactly what they need from a set of high-quality, interoperable components.

Application Areas

The EATON XV-303-15-C00-A00-1B​ is a versatile switching component used as the core of control assemblies for various electrical loads.
Its applications are broad, typically forming part of:
  • Motor Starters:​ When combined with an overload relay, it forms a direct-on-line (DOL) starter for three-phase motors up to its rated HP (approx. 5-7.5 HP at 400V).
  • Load Switching:​ Controlling heaters, transformers, capacitor banks, or lighting panels.
  • Industrial Control Panels:​ As a general-purpose contactor within machine control cabinets for automating processes.
  • HVAC & Building Automation:​ In control systems for fans, pumps, and compressors.
Essentially, it is used wherever reliable, remote-controlled switching of a moderate-power three-phase or single-phase AC load is required, and where a modular design philosophy is adopted for flexibility and serviceability.

Related Products

  • Overload Relay (Thermal or Electronic):​ Must be selected to match the contactor’s frame size and current rating (e.g., an Eaton PKZ overload relay). This adds motor protection.
  • Mounting Base or DIN Rail Adapter:​ If not integral, for physical installation.
  • Auxiliary Contact Blocks:​ Additional contact blocks can often be added to the sides of the contactor to increase the number of signaling contacts.
  • Mechanical or Electrical Interlock:​ For reversing starter applications.
  • Control Coil:​ The coil itself might be a separate, plug-in module defined by the C00code.
  • Enclosure:​ A suitable NEMA or IP-rated enclosure to house the assembled starter.
  • Control Devices:​ Pushbuttons, selector switches, or PLC outputs to operate the coil.
