Product catalog summary

Overview: The document provides comprehensive technical specifications and features of IDEC's NC1V series circuit breakers, focusing on their application, design, and operational characteristics. It covers various models, configurations, and performance under different conditions.

Specifications: NC1V circuit breakers are designed for superior protection of sensitive electronic equipment and electrical control circuits. They feature a hydraulic magnetic tripping system and are available in 1, 2, and 3-pole configurations. The rated voltage is 250V AC (50/60Hz) and 65V DC, with a tripping current range from 0.1A to 30A.

Key Features: The series offers excellent tripping time curve performance, a flat retractable lever for safety, a slim housing design, and spring-up terminals for ring terminal use. Additional features include a color-coded contact position indicator and options for DIN rail or direct panel mounting, with optional built-in auxiliary and alarm contacts.

Protection and Performance: Protection is provided through hydraulic magnetic and electromagnetic trip methods, with optional inertial delay to resist high inrush currents. Time delay curves are categorized as slow (M), medium (A), and instantaneous (S). The breakers are UL, CSA, CE, TUV, and CCC certified.

Operational Characteristics: Details include rated short-circuit capacity, operation characteristics, and auxiliary/alarm contact ratings. Information on insulation resistance, dielectric strength, vibration and shock resistance, and electrical life expectancy is also provided.

Environmental Considerations: Designed to operate within a temperature range of -10 to +60°C and a humidity range of 45-85% RH. The rated current is based on an ambient temperature of 40°C, with derating factors for higher temperatures.

Models and Configurations: Various models are specified by rated current, time delay curve, and voltage trip coil voltage. Detailed part number structures and internal circuit diagrams for different configurations, including series trip and relay trip types, are included.

Time Delay and Temperature Effects: Ambient temperature affects time delay, with correction curves provided for different temperatures. Impedance and coil resistance for series and relay trip configurations are discussed.

Conclusion: IDEC's NC1V series circuit breakers offer robust protection and flexibility for a wide range of applications, with detailed specifications ensuring they meet diverse operational requirements.

Additional Specifications: Includes dimensions for 1-pole, 2-pole, and 3-pole models, terminal screw types and sizes, and applicable wire sizes and crimp terminals for different current ratings.

Voltage Drop Considerations: Highlights the importance of considering voltage drop due to coil resistance or impedance, especially in breakers with smaller rated currents. Internal resistance varies with time delay curves.

Installation Instructions: Outlines the installation process on DIN rails, including secure fastening and using a flat screwdriver for removal. Guidance on panel mounting screws and installation angle is provided.

Product Markings and Certifications: Details on product markings, including PSE certification, reference operating temperature, auxiliary/alarm contact rating, time delay curve, number of poles, certification marks, rated current, and voltage. Instructions for installing auxiliary/alarm terminal covers are included.

Accessories: Lists available accessories such as panel cut-out mounting brackets, marking plate holders, padlock attachments, and replacement auxiliary/alarm terminal covers.
