## Long description

The Zamel STM-25-30 modular installation contactor is a high-quality electrical component engineered for the reliable switching of power circuits in various building installations. With a rated current of 25A and three normally open (3NO) contacts, this device provides a robust solution for managing electrical loads in both residential and commercial environments. It is designed for seamless integration into standard distribution boards, operating efficiently on a 230V AC control voltage to ensure consistent performance and safety in electrical distribution systems.
Advantages
This contactor stands out due to its modular design, which allows for quick and easy installation on standard DIN rails within electrical cabinets. The construction utilizes high-grade materials that ensure long-term operational stability and resistance to mechanical wear. By providing three normally open contacts, it offers versatile control options for multi-phase or high-load single-phase circuits. Its silent operation and reliable switching mechanism make it an excellent choice for environments where consistent power management is required without frequent maintenance.
Suitable for
Switching lighting circuits in residential and commercial buildings
Controlling heating systems and electric radiators
Managing ventilation and air conditioning units
Automating electrical loads in smart home installations
When it may not be suitable
This device is not intended for use in circuits exceeding its 25A rated current capacity or for applications requiring a different contact configuration, such as normally closed contacts. It is also not suitable for environments with extreme moisture or high levels of dust unless housed in an appropriate protective enclosure.
Key specifications
Rated current: 25A
Contact configuration: 3 normally open (3NO)
