Product catalog summary

Ratings and Specifications
Molded Case Circuit Breakers (MCCBs) are available in fixed and adjustable thermal and magnetic types. Key specifications include rated current, insulation voltage, impulse withstand voltage, and breaking capacity. Detailed ratings are provided for models like S160-SF and E250-SF, covering rated current, breaking capacity, and dimensions.

Mounting and Connection
The document describes connection types and mounting options for MCCBs, such as front-connected, rear-connected, and plug-in types. It includes details on compression terminals, extension bars, and cable clamps, with specific configurations for different breaker models.

Accessories
Internally mounted accessories include auxiliary switches, alarm switches, shunt trip devices, and undervoltage trip devices. Externally mounted accessories include motor operators, toggle holders, and external operating handles. Compatibility and installation options for each accessory type are specified.

Characteristics and Outline Dimensions
Dimensions and characteristics for various MCCB models are detailed, highlighting compact size and high breaking capacity. Features include IP20 and IP30 protection levels, unique accessory covers, and adjustable overload protection.

Features
Key features include varied terminations, compact size, high breaking capacity, and suitability for operation in pollution degree 3 environments. The document emphasizes ease of installation for internal accessories and secure design of accessory covers.

Specifications for Motor Operators
The document outlines specifications for motor operators used in circuit breakers, with rated operational voltages ranging from AC100-110V to DC200-220V. Peak steady-state and starting currents are specified, and motor operators are designed for short-time duty with a maximum of 10 continuous ON-OFF operations before a 15-minute cooling period. Operating time at rated voltage is 0.1 seconds for both ON and OFF/RESET operations.

Procedures
Motorized operation involves an input-signal self-hold circuit, while manual operation requires pulling and rotating the handle. An auto-reset feature automatically resets the breaker approximately 1.5 seconds after tripping.

Standards and Recommendations
The document recommends maintaining operation voltage between 85% and 110% of the rated voltage and using noise filters if the control power supply is shared with peripheral devices. Electrical interlock cables are advised when using motors with mechanical interlocks.

Features of Motor Operators
Motor operators offer high-speed, stable actuation with silent operation due to the direct drive system. They also have a "lock-in off" capability, allowing the breaker to be padlocked in the OFF state with up to three padlocks.

Accessories for Motor Operators
Accessories include interlock cables and external operating handles, which allow operation from outside a switchboard and include a panel lock mechanism.

Overview
The document provides detailed technical specifications and accessory options for various MCCB models, including dimensions, mounting options, and additional accessories to enhance functionality and safety.

Specifications
Dimensions and configurations for different breaker models are outlined, specifying component lengths and distances from the panel surface to the breaker mounting surface.

Accessories
Accessories such as external operating handles, interpole barriers, terminal covers, terminal blocks, and mechanical interlocks are detailed with their purpose, dimensions, and compatibility.

Interpole Barriers
Used to enhance electrical insulation between poles and prevent short circuits, interpole barriers cannot be used with terminal covers.

Terminal Covers
Available for front-connected, rear-connected, and plug-in breakers, terminal covers prevent exposure of live parts and come in various sizes and colors.

Mechanical Interlock
The slide interlock mechanism prevents two breakers from being closed simultaneously, with dimensions and order codes provided.

Door Flanges
Recommended for covering switchboard panel cutouts, door flanges are detailed with dimensions and installation instructions.

Ratings and Specifications
Includes ratings for current, voltage, and breaking capacity, along with time/current characteristic curves and ambient compensating curves for different breaker models.

Installation and Mounting
Instructions for mounting and connecting breakers are provided, including details on terminal screws, bolt studs, and plug-in options, along with drilling plans and panel cutout dimensions.

Conclusion
This technical document serves as a comprehensive guide for selecting and installing molded case circuit breakers and their accessories, ensuring proper configuration and safety in electrical systems.
