The TBC TCT Series Modular Contactor is engineered for reliable remote and automatic switching of electrical circuits in residential, commercial, and building management systems. Designed to IEC/EN 61095 standards, the TCT-225 offers robust electromagnetic control for lighting, heating, and general-purpose loads with low power consumption and long operational life.
The TCT-225 Modular Contactor is a professional-grade switching device designed for integration into modern electrical distribution systems. Its electromagnetic operating principle ensures reliable, silent operation ideal for building automation and remote control applications.
With a utilization category of AC-7a, this contactor is specifically suited for low inductive loads such as lighting circuits, heating elements, and general residential or commercial applications. The compact 1-module width allows for space-efficient installation in crowded distribution boards.
The device features clearly marked terminals (1-2 / 3-4 for main contacts, A1-A2 for coil) for straightforward wiring and maintenance. Its continuous duty control method ensures stable performance in demanding applications requiring frequent switching operations.
Important: This modular contactor does not provide overload or short-circuit protection and must be used in combination with appropriate protective devices such as MCBs, MCCBs, or ELCBs.
Operating Principle: The TCT-225 operates on an electromagnetic principle where energizing the control coil (A1-A2) with 230V AC creates a magnetic field that closes the main contacts, allowing current flow through the load circuit. De-energizing the coil releases the contacts to their normally open state.
Electrical Characteristics: The contactor is rated for 25A operational current at 250V AC with a rated insulation voltage of 500V AC, providing adequate safety margins for typical residential and commercial applications. It operates on standard 50/60 Hz frequency systems.
Contact Configuration: Features 2 normally open (NO) main contacts with integrated auxiliary contacts (model dependent). Terminal markings follow standard conventions for easy identification during installation and maintenance.
Mechanical Performance: Engineered for durability with a mechanical life exceeding 1 million operations and electrical life of over 100,000 operations. Suitable for switching frequencies up to 100 operations per hour, making it ideal for automated control systems.
Environmental Ratings: IP20 protection rating suitable for indoor distribution board installation. Operating temperature range of -5°C to +40°C covers most indoor environments, with storage capability from -25°C to +70°C.
Installation: Mounts on standard 35mm DIN rail per EN 60715. Vertical installation position is recommended for optimal performance. Compact dimensions (81mm H × 18mm W × 68mm D) allow efficient use of panel space.
