Phoenix CSS Series Components Product Selection Guide

In industrial circuit signal filtering, electromagnetic compatibility (EMC) optimization and low-voltage circuit protection scenarios, Phoenix CSS series components are highly recognized for their excellent anti-interference performance, precise parameter matching and compact structural design. This guide collates the product codes, models and detailed descriptions of CSS series models, helping electrical design, procurement and maintenance personnel quickly select suitable products for different industrial EMC optimization and circuit signal processing requirements.

1. CSS Series Core Model List (With Product Descriptions)

2. Quick Interpretation of CSS Series Model Naming Rules

Mastering the naming logic of CSS series models can help you quickly identify the core parameters and applicable scenarios of the product:

1. Series Prefix: CSS is the core series identifier, representing Phoenix's dedicated EMC optimization and signal filtering components for industrial circuits.
2. Rated Current Parameter: The number before the first hyphen (e.g., 1.5, 0.75) refers to the rated current of the component, determining the maximum current that the product can stably bear in the circuit.
3. Core Matching Parameter: The number group between the two hyphens (e.g., 1/3, 3/3) is the core matching parameter of the component, which is closely related to the impedance matching, filtering frequency band and interference suppression effect of the circuit.
4. Function Suffix: The suffix EMC indicates that the component has professional electromagnetic compatibility optimization function, which can effectively suppress electromagnetic interference in industrial environments and improve the stability of signal transmission.

3. Core Advantages of Phoenix CSS Series Components

1. Targeted EMC Optimization: The dedicated EMC function design can effectively suppress electromagnetic interference generated by industrial equipment such as motors and frequency converters, improving the anti-interference ability of signal circuits.
2. Precise Parameter Matching: Provides multiple core matching parameters (1/3, 3/3) and rated current options (0.75A, 1.5A), which can be accurately matched with different types of low-voltage industrial circuits.
3. Compact Structure Design: Miniaturized product size, occupying a small installation space in the control cabinet, suitable for dense wiring scenarios of industrial automation systems.
4. Strong Compatibility: Standard interface design, compatible with most of Phoenix's terminal blocks and mounting rails, realizing seamless integration with existing industrial circuit systems.
5. Stable Performance: Passes strict industrial environment reliability tests, with stable operation under high temperature, high humidity and strong electromagnetic interference scenarios, ensuring long-term EMC optimization effect of the circuit.

4. Product Selection Suggestions

1. Rated Current Matching: First determine the working current range of the target circuit, select the 1.5A model for medium-current signal circuits, and the 0.75A model for small-current control circuits and low-power signal transmission circuits.
2. Core Parameter Selection: According to the impedance characteristics and filtering frequency band requirements of the circuit, select the corresponding core matching parameter model (1/3 or 3/3). It is recommended to refer to the product technical manual or consult professional engineers for precise matching.
3. Scenario Orientation Confirmation: Prioritize CSS series models for industrial circuits with high requirements for electromagnetic compatibility (such as precision instrument signal circuits, communication bus circuits); for general circuits without EMC requirements, you can choose conventional components to reduce costs.
4. Installation Compatibility Check: Confirm that the selected model is compatible with the existing terminal blocks and mounting rails of the equipment to ensure smooth installation and commissioning.
