Timer

A timer relay switches its contacts after a set delay. In control panels it is used to sequence operations, for example to change a motor from star to delta after starting, or to delay a generator transfer until the voltage is stable.

Available ratings

• 8 Pin : 12 Pin
• 220V, AC : 24V, DC

Where it is used

• Star-delta motor starters
• ATS and generator changeover panels
• Pump, fan and lighting sequencing
• Machine and process control

How to choose

• Function: on-delay, off-delay, star-delta or multi-function.
• Base: 8-pin or 12-pin plug-in, or DIN rail.
• Supply voltage: 220 V AC or 24 V DC.
• Time range that covers the delay you need.

Why buy from Unique Quality Engineering

Frequently asked questions

What does a star-delta timer do?

It keeps the motor in star connection for a few seconds while it starts, then switches it to delta for normal running.

What is the difference between 8-pin and 12-pin timers?

The number of pins sets how many contacts the timer has. 12-pin models usually have more contacts for extra interlocking.

Which time setting is normal for star-delta?

Usually 5 to 10 seconds, until the motor reaches close to full speed. It depends on the machine.
