JUTRION Motorized Operating Mechanism is designed to enable remote and automated ON/OFF control of molded case circuit breakers (MCCBs). With a highly compatible and modular design, it can be applied to most mainstream MCCBs on the market, helping users upgrade conventional power distribution systems to automated and intelligent operation.The mechanism provides stable and reliable motor-driven ON/OFF operation and supports multiple control interfaces, including RS485 communication, PLC digital control, and mobile-based remote control systems. It can be easily integrated into existing automation systems, energy management platforms, and smart power distribution networks.Through RS485 or PLC interfaces, the motorized operating mechanism can be connected to supervisory systems for centralized monitoring and control. With optional gateway or cloud-based solutions, users can also realize remote operation and status monitoring via mobile devices, improving system responsiveness and operational efficiency.For MCCB brands or models outside the standard compatibility range, JUTRION offers free customization services. By evaluating the mechanical structure and operating interface of the circuit breaker, customized solutions can be developed to ensure proper fitting, smooth operation, and long-term reliability. This flexible approach helps customers reduce retrofit costs and shorten project lead times.With high compatibility, flexible control options, and reliable mechanical performance, the JUTRION motorized operating mechanism is an ideal solution for upgrading MCCBs in power distribution automation, industrial control systems, smart buildings, and renewable energy applications.

Overview：

The CD2 series motorized operating mechanism (hereinafter referred to as the motor operator) is driven by a small permanent-magnet DC motor. It is a dedicated actuator used for remote closing, opening, and reclosing operations of molded case circuit breakers (MCCB) rated from 63A to 1250A.

It enables remote control or centralized control of various electrical equipment.

Features：

1. Compact structure, small size, convenient installation, and reliable operation. The breaker can also be operated manually using the operating handle.
2. The product adopts internationally advanced “switch power supply” technology, and its mechanical life, electrical life, and reliability are comparable to similar international products.
3. The CD2 series motor operator supports both AC and DC power supply, with a wide control circuit voltage range and low operating current.
4. Colored indicators (red, green, and white) are provided to indicate the closing, opening, and tripping status of the circuit breaker.
