In modern electrical vocational education and university electrical engineering courses, practical training is the core link to bridge theoretical knowledge and industrial application. For the teaching of magnetic starter control, motor circuit installation, electrical debugging and fault maintenance, a set of industrial-standard, highly operable and safe teaching experimental equipment is essential. Today, we will introduce the MR596E Educational and Laboratory Stand , a professional training equipment tailored for college electrical courses, focusing on electrical installation and adjustment of magnetic starters and hardware component operation training.

1. Product Overview: Professional Customization for Electrical Teaching Scenarios
1.1 Product Description
The MR596E educational and laboratory stand is independently developed and manufactured targeting the practical teaching needs of college electrical engineering, automation, mechatronics and other majors. It abandons the simplified and non-industrial design of traditional teaching experimental equipment, and fully adopts industrial-grade core configuration , integrating industrial circuit breakers, contactors, precision measuring instruments and dual asynchronous motor systems.
The equipment adopts a mature open modular design, which breaks the closed experimental mode of traditional teaching equipment. All circuit construction, component wiring and equipment debugging links need to be completed independently by students. It covers core practical training projects such as main circuit wiring, star-delta step-down starting control, motor start-stop adjustment and circuit fault troubleshooting. Through hands-on operation, it systematically cultivates students' comprehensive abilities of electrical system design, on-site installation, parameter debugging and fault diagnosis.
In terms of safety and compatibility, the equipment supports AC380V/220V dual power input, and strictly complies with the national GB/T 5226.1 electrical safety standard . It has complete electrical protection mechanisms, effectively avoiding electric leakage, short circuit and overload risks in the experimental process, and ensuring safe and standardized teaching and training.
1.2 Core Product Features
Different from ordinary teaching experimental platforms, MR596E has obvious advantages in industrial simulation, practicality and teaching comprehensiveness, with four core highlights:
1. Real restoration of industrial application scenarios
The equipment fully copies the actual electrical control circuit and magnetic starter working scenario in industrial production. The component layout, circuit logic and operation mode are consistent with industrial field standards, enabling students to get familiar with industrial electrical operation specifications in advance and realize zero-distance docking with post-industrial work scenarios.
 
 
2. Full industrial brand core components
All key electrical components such as circuit breakers, AC contactors and thermal relays are selected from formal industrial brands, with stable performance and long service life. Compared with teaching-specific simplified components, industrial components have more accurate parameter response and more real working state, which ensures the authenticity and accuracy of experimental training results.
3. Fully exposed terminal design, focusing on hands-on training
All component wiring terminals of the equipment are open and exposed, with no pre-embedded hidden circuits. Students need to match supporting wires according to experimental principles, independently complete circuit layout, wiring, connection and calibration. This design effectively exercises students' circuit analysis ability and hands-on wiring skills, avoiding the mechanical operation of plug-and-play of traditional experimental equipment.
4. Rich and expandable experimental projects
The platform supports a variety of core electrical control experiments, including motor inching control, forward and reverse rotation control, star-delta step-down starting, relay overload protection, circuit fault detection and other practical training projects. It covers the key knowledge points of magnetic starter installation, debugging and hardware component operation, meeting the teaching needs of basic experiments, skill training and comprehensive practical training.
