Every spec below is cited to the manufacturer datasheet. Pick your exact ordering code, compare the closest alternatives, then ask the assistant what it means for your design.

00 — Overview

What the G5NB-1A family does

The G5NB-1A family comprises miniature PCB power relays featuring a 1-pole SPST-NO contact form with 3A or 5A switching capability and 10 kV impulse withstand voltage. These units operate on 5V, 12V, 18V, or 24V DC coils and offer standard or high-capacity contact ratings. Key parameters include 10 ms operate/release times, 100 mΩ maximum contact resistance, and 250,000 minimum electrical operations. The series supports UL/CSA/VDE standards and satisfies EN61010 reinforced insulation requirements. Variants include flux protection, sealed enclosures, and home appliance classifications. They are typically used in water heaters, air conditioners, refrigerators, and other small electric appliances.
