Control and Switching
Choose electrical relays by coil voltage, contact rating, function and installation format
DistriNode electrical relays are used in distribution boards, control cabinets, machinery, HVAC, lighting, automation and smart building circuits. Compare coil voltage, AC or DC control, contact configuration, switching current, DIN rail mounting, plug-in sockets, timer and impulse functions, interface isolation, monitoring features and manufacturer documentation before replacing or designing a circuit.

How to Choose Electrical Relays
Match coil voltage
The control side must match the available AC or DC voltage in the circuit.
Check contacts
NO, NC, changeover, pole count and contact rating define what the relay can switch.
Choose function
Impulse, timer, interface, monitoring and power relays solve different control tasks.
Plan installation
DIN rail, socket, PCB and panel formats are not interchangeable without the right base.

Electrical note: Relay replacement should match coil voltage, contact load and function. If the circuit controls mains voltage, installation should be handled by a qualified electrician.
Frequently Asked Questions
What is coil voltage?
It is the voltage used to activate the relay, separate from the load being switched.
Can a relay switch any load below its amp rating?
Not always. Motor, LED, capacitive and inductive loads can require derating or special relay types.
What is an impulse relay used for?
It changes state with a pulse and is often used for lighting control from several buttons.
