Why choose it

The AgNi contacts handle high inrush currents, and the 6 kV isolation between coil and contacts protects control circuits from voltage spikes. Flux-proof construction resists contamination during wave soldering.

Ideal use cases

• Switching motors, heaters, and lighting in industrial automation
• Interface between PLC outputs and high-power loads
• PCB assemblies requiring a compact, high-current relay

Good to know

Approvals include VDE, UL, and CSA. The relay is supplied in single-unit packaging.
