Heating and ventilation equipment management
Industrial motor control circuits
General electrical load switching in distribution boards
This device is not intended for high-voltage industrial power grids exceeding its rated capacity or for applications requiring specialized hazardous environment protection. It should not be used in circuits where the current draw consistently exceeds the 25A threshold, as this may lead to overheating or premature failure of the internal contacts.
Key specifications
Rated current: 25A
Coil voltage: 230V AC
Contact configuration: 3 normally open (NO) and 1 normally closed (NC)
Mounting type: TH35 rail
Series: EXTA
To use the Zamel STM-25-31, mount the device onto a standard TH35 DIN rail within a distribution enclosure. Ensure that the power supply is disconnected before performing any wiring. Connect the control circuit to the coil terminals and the load circuit to the main power terminals, ensuring that all connections are tightened securely to prevent loose contacts. Once installed, verify the operation of the contactor by energizing the control coil.
What to consider before purchase
Verify that your control circuit voltage matches the 230V AC coil requirement
Ensure the total load current does not exceed the 25A rating
Confirm available space on the TH35 rail within your electrical panel
Check if the 3NO 1NC contact configuration meets your specific switching logic needs
Ensure that the installation is performed by a qualified electrician in accordance with local electrical safety regulations to guarantee long-term reliability and safety.
