When you need to manually switch between power sources in high-current applications, the YCHGLZ1-400 manual transfer switch from CNC Electric provides the robust performance and safety you can trust. Designed for commercial, industrial, and utility use, this 400-amp switch ensures seamless transition between primary and backup power sources with exceptional durability and ease of operation.
Built to meet rigorous international standards, including IEC 60947-3, this manual transfer switch is engineered for infrequent but reliable switching and safe electrical isolation. Its modular design allows flexible configurations to match your specific electrical layout, whether you're managing dual power supplies, backup generators, or critical load transfers.
The switch housing is manufactured from high-grade DMC (Dough Molding Compound) material, offering excellent dielectric strength, impact resistance, and flame-retardant properties. This ensures reliable operation and enhanced safety in diverse environmental conditions.
Unlike conventional switches that depend on operator speed, our transfer switch utilizes a spring-stored energy mechanism with instant release acceleration. This design delivers consistent, quick switching action regardless of how fast or slow the handle is turned, significantly improving both electrical and mechanical longevity.
The instant connection/disconnection dual-breakpoint contact design minimizes arcing, reduces contact wear, and enhances overall switching performance. This results in a longer operational life and reduced maintenance needs.
Choose between front-operated or side-operated configurations based on your panel layout and accessibility requirements. The side-operated version is particularly useful when side access is preferred or space constraints exist.
The switch includes a clear position indicator, allowing operators to instantly verify whether the switch is connected to the normal power source, alternative source, or is in the off position—reducing the risk of human error.

What is the main advantage of a manual transfer switch over an automatic one?
Manual transfer switches are typically more cost-effective, simpler in design, and ideal for applications where an operator is present to initiate power source switching. They provide direct control and eliminate the complexity of automatic controllers.
Can this switch be used with generator systems?
Yes, the YCHGLZ1-400 is commonly used as a manual generator transfer switch to safely transition between utility power and backup generator power. Its robust design handles the high inrush currents associated with generator startup.
Is this switch suitable for three-phase systems?
Absolutely. The switch is available in 3-pole and 4-pole configurations, making it perfectly suited for three-phase power systems commonly found in industrial and commercial settings.
What safety features are included?
The switch incorporates a double-break contact design for reliable circuit interruption, an insulated housing for operator protection, and a clear position indicator to prevent accidental connection to the wrong power source.
