Relay for 12 V switching

The Vszerda ZD4115-S-A is a single normally open relay with a 4-pin layout designed for 12 VDC coil operation. It suits hobbyists and technicians who need to control a separate AC circuit from a low-voltage source.

Thermals noise and power

The coil draws modest current at 12 V and the contacts are rated for 30 A at 250 VAC. No active cooling is required and the device runs silently during normal switching.

Highlights

  • Handles 30 A loads for high-power switching
  • 12 V DC coil suits common control circuits
  • Single normally-open contact simplifies wiring
  • 250 V AC rating fits mains applications

Questions about this item

How do I wire the 12 VDC coil and the 4-pin normally open contacts on the ZD4115-S-A relay?

Apply 12 VDC across the coil pins; the load circuit connects to the two normally open contact pins and closes when the coil is energised.

When should I replace the ZD4115-S-A relay in a 30 A 250 VAC switching application?

Replace it when the contacts show pitting, the coil fails to pull in at 12 VDC, or the switching cycle count approaches the manufacturer's rated endurance.
