Timer Relays

Timer relays from ABB, Siemens and Schneider Electric provide on-delay, off-delay, flasher and star-delta timing for control panels. The range includes ABB CT-S, CT-D and CT-C types, Siemens 3RP2 and Harmony timer relays, with contact ratings from 0.7 A to 16 A. Stoklink ships worldwide from Turkey and quotes project volumes on request.

What's in this range

• Multifunction timer relays that combine several time functions in one unit, such as ABB CT-MFD and CT-MVS or Harmony RE22 and RE48.
• Star-delta timers for motor starting, for example ABB CT-SDD.
• Flasher and asymmetrical flashing timers.
• Siemens SIRIUS 3RP2 timing relays with universal supply voltage.
• Staircase light switches with timing function.

How to choose

• Time function: on-delay, off-delay, pulse, flasher or star-delta.
• Time range: select a range where your required delay is not at the extreme ends of the dial.
• Supply voltage: 24-48 V DC with 24-240 V AC universal supply is common.
• Contact output: one or two C/O contacts and the load current at 250 V.
• Width and mounting: DIN rail modules or 8-pin and 11-pin plug-in formats.

FAQ

When do I need a star-delta timer?

When a squirrel-cage motor starts in star and then switches to delta. The timer sets the changeover delay and a short pause between the two contactors.

What is a multifunction timer relay?

A single device where you select among several time functions with a rotary switch. It reduces the number of part numbers you stock for spares.

Do you quote timer relays in volume?

Stoklink ships worldwide from Turkey, EXW. Lead time depends on distributor stock, and project quantities are quoted on request.
