Why choose it

This relay combines high switching capacity with low coil power consumption, reducing heat generation and energy use in your control circuits. The AgNi contacts ensure reliable switching even under demanding conditions, while the flux-proof housing protects against contamination during soldering and operation. Its wide temperature range makes it suitable for both indoor and harsh environments.

Ideal use cases

• HVAC and building automation systems
• Industrial control panels and PLC outputs
• Lighting and motor control circuits
• Appliance controls requiring 16 A switching

Good to know

The RKAk-E10 is a PCB relay, so it is soldered directly onto a printed circuit board. Ensure proper heat management during soldering and verify that the coil voltage matches your control signal. The green colour aids in visual identification, and the relay is approved by VDE, UL, and CSA for global compliance.
