Why Choose the Finder 83.82.0.240.0000T Star-Delta Timer Relay?
The Finder 83.82.0.240.0000T is a compact DIN rail mounted star-delta timer relay designed for timed switching in industrial motor control, automation and electrical control panels. Part of the Finder 83 Series, this modular timer provides a dedicated star-delta timing function for coordinating the transition between star and delta contactors in suitable three-phase motor starting circuits.
Featuring a 24–240 V AC/DC supply range, two normally open relay outputs and a 16 A contact rating, the Finder 83.82.0.240.0000T provides a practical interface for motor starter control circuits. The timer operates the star output first, then introduces an adjustable transition interval before energising the delta output, helping coordinate the required starting sequence.
The T-version is intended for demanding industrial and railway-related applications. Its 22.5 mm wide housing, screw terminal connections and standard 35 mm DIN rail mounting allow straightforward integration into compact control cabinets, motor starter assemblies and automation equipment.

Controlled Star-Delta Switching for Three-Phase Motor Starters
The Finder 83.82.0.240.0000T operates using the SD star-delta timing function. When supply voltage is applied, the star output closes immediately, allowing the associated star contactor to energise. After the selected star operating time has elapsed, the star output opens. Following an additional adjustable transition interval of 0.05–1 s, the delta output closes and remains operated until the timer supply is removed.
This switching sequence helps coordinate the contactors in a conventional star-delta motor starter. Star-delta starting can reduce the starting current compared with direct-on-line starting for suitable motors, although it also reduces available starting torque. The Finder timer controls the sequence; it does not replace the main, star and delta contactors, their required electrical and mechanical interlocks, motor overload protection or other necessary protective devices.
Typical Applications
- Three-phase star-delta motor starter control circuits.
- Industrial motor control centres and electrical panels.
- Pump motor starting systems.
- Industrial ventilation and fan motor control.
- Compressor motor starter assemblies where star-delta starting is appropriate.
- Industrial machinery motor starting sequences.
- Conveyor and material handling equipment.
- Manufacturing and process automation systems.
- OEM motor control equipment.
- Industrial electrical distribution and switchgear assemblies.
- Railway-related auxiliary motor control applications.
- Control panels requiring coordinated star-to-delta contactor switching.

Frequently Asked Questions
What is the Finder 83.82.0.240.0000T used for?
The Finder 83.82.0.240.0000T is a star-delta timer relay used to control the switching sequence between star and delta contactors in suitable three-phase motor starter circuits.
What supply voltage does the Finder 83.82.0.240.0000T require?
The timer is designed for a nominal supply range of 24–240 V AC/DC, allowing operation from compatible AC or DC industrial control supplies.
How does the star-delta timing function work?
When the timer is energised, the star output closes immediately. After the selected star operating period, that output opens. Following the adjustable transition interval, the delta output closes and remains energised until the supply is removed.
How many output contacts does the timer have?
The Finder 83.82.0.240.0000T provides two normally open (2 NO) relay outputs, with separate functions for controlling the star and delta contactors.
What is the rated contact current?
The timer has a 16 A rated contact current and a 250 V AC rated contact voltage. The permissible switching load depends on the connected equipment and applicable utilisation category.
Can the star-to-delta transition time be adjusted?
Yes. The timer provides an adjustable transition interval of 0.05–1 s between the opening of the star output and the closing of the delta output.
Does the Finder 83.82.0.240.0000T switch the motor directly?
No. The timer provides control signals for compatible star and delta contactors. The motor power circuit must use appropriately rated contactors, interlocking arrangements and protective devices.
What is the difference between the Finder 83.82 and 83.62 timers?
The Finder 83.82 is designed for star-delta motor starting sequences, whereas the Finder 83.62 provides a true power off-delay function. They perform different timing operations and are not direct functional substitutes.
Can this timer be installed on a DIN rail?
Yes. The Finder 83.82.0.240.0000T is designed for 35 mm DIN rail mounting and features a compact 22.5 mm wide housing for electrical control panels.
What does the T suffix identify?
The T suffix identifies a variant intended for demanding applications, including railway-related installations. Applicable environmental qualifications and approvals should be checked against the manufacturer's documentation for the exact part number.
Does the timer provide motor overload protection?
No. The Finder 83.82.0.240.0000T is a timing and control device, not a motor overload relay or circuit breaker. Suitable motor protection, contactor interlocking and upstream circuit protection must be provided separately.
