Q1: What is concealed slot design and what are its advantages?

A: The concealed slot design hides the connection slots at the edge of the base, creating a seamless appearance with no exposed parts. This design improves fitting accuracy, enhances dust protection, and gives distribution panels a cleaner, more professional look — ideal for high-end commercial and industrial projects where cabinet appearance matters.

Q2: How many color options are available for ZY2-L series?

A: The ZY2-L series offers 5 standard colors: white, orange-white, red, green, and full orange. Custom colors are available for large orders, allowing you to match your brand identity or project requirements.

Q3: Is the module replaceable without rewiring?

A: Yes. All ZY2-L series SPDs feature plug-in modular design. The module can be directly pulled out and replaced while the base remains mounted on the DIN rail — no rewiring needed, minimizing downtime.

Q4: What voltage ratings are available for ZY2-L AC?

A: ZY2-L AC series is available in 275V AC and 385V AC voltage ratings, suitable for standard single-phase and three-phase AC power distribution systems in residential, commercial, and industrial applications.

Please make sure to select the appropriate components according to your actual needs. Operating beyond the marked current and voltage ranges will render the product unusable.

Q5: What current ratings does ZY2-L AC offer?

A: ZY2-L AC series offers three current rating options: 20D (5kA/10kA), 25D (10kA/20kA), and 34S (20kA/40kA). 34S is the standard mainstream specification for most applications.
