Power connection
Our relays are typically used here
- In generator sets and emergency power systems for safe engine starting and grid synchronisation
- In cooling and pump systems for reliable motor control and protection
- In industrial installations for monitoring speed, voltage and phase conditions
- In control panels for engine start, immobiliser and overspeed control
- When operating generators in parallel to prevent damage and malfunctions
- In systems where stable and automated power connectivity is essential

Power connection and control relays for safe motor control and grid synchronisation
Reliable solutions for power connection and motor control are essential in installations with generators, chillers, pump systems and other motorised devices. Thiim offers a wide range of relays for engine starting, immobilisation, overspeed monitoring and synchronisation control to ensure efficient and safe operation.
An engine starter relay is used to automatically start petrol, gas or diesel engines and protects against misfiring or incorrect starting. Immobiliser relays prevent the starter from activating when the engine is already running, while an overspeed relay monitors the frequency of the engine and cuts out in case of a fault in the speed control system - protecting both the engine and connected components.
For parallel operation or grid connection, our synchronisation control relays ensure that the generator is only connected to the grid under correct voltage and phase conditions. This prevents damage to the generator and reduces the risk of outages or errors in the installation.
Thiim relays are suitable for mounting in control panels and are used in generator sets, emergency power systems, industrial cooling systems and pump units.

Synchronisation control
SYND-SYPD
Synchronisation relay - with optional panel indicator - SYND-SYPD
A compact synchronisation relay that ensures precise control of switchgear and emergency power systems with clear status display and remote indication via SYPD.
Enables fast and secure resynchronisation during power outages and requires minimal board space.
Benefits:
- Detects and compares voltage and phase angle between two AC supply systems
- Detection of de-energised busbar
- Compact design for DIN rail mounting
- User-adjustable output type - pulse signal or constant signal
- Real-time LED indication of generator speed vs. allowed deviation from the main bus
