Since 2002, TOMZN has been a trusted manufacturer of high-quality electrical protection and control devices, with a strong focus on new energy and smart home solutions. The TOMZN contactor series, particularly the TOCT1 lineup, provides dependable, compact modular contactors designed for seamless integration into modern electrical systems. These DIN rail household AC modular contactors excel in remote switching, automation, and load control, offering installers and homeowners a cost-effective way to manage lighting, heating, ventilation, pumps, and other AC loads safely and efficiently.
Why Modular Contactors Are Essential for Modern Electrical Systems
In today’s energy-conscious environments, reliable switching is key to automation, energy savings, and equipment protection. Unlike traditional relays or manual switches, modular contactors handle higher currents with low coil power consumption, enable remote or timed control, and support multiple configurations for flexible applications. TOMZN’s AC modular contactors are built for AC 50/60Hz circuits up to 230V, making them ideal for residential distribution boards, smart home setups, and light commercial installations. Their compact DIN rail design saves space while ensuring easy installation and maintenance.
TOMZN Contactor Product Range: Focused on Versatility and Performance
TOMZN’s contactor category centers on the TOCT1 series of household AC modular contactors, engineered for reliability and user convenience:
- TOCT1 2P Modular Contactors The core offering features 2-pole (2P) configurations with current ratings from 16A to 100A (popular models include 16A, 20A, 25A, 63A, and 100A). These handle rated operating voltages up to 230V AC in AC-7a/AC-7b usage categories. Contact arrangements include 2NO (Normally Open), 1NO 1NC, 2NC, and more for diverse switching needs.
- TOCT1 4P Modular Contactors Available in higher-pole options like 4P (4-pole) for three-phase or multi-circuit control, with ratings such as 25A and 63A. Configurations support 4NO, 2NO 2NC, or 4NC to accommodate complex loads like multi-phase lighting or motors.
- Coil Voltage Options Wide flexibility with AC coil voltages (220V/230V, 110V, 24V) and DC coil variants (12V, 24V) in select models like TOCT1-25-Z. This compatibility suits both standard AC panels and low-voltage DC control circuits, including integration with batteries or solar setups.
- Auxiliary Contactors and Accessories The O+F auxiliary contactor series pairs perfectly with TOCT1 models, adding 2NO or 1NO 1NC contacts for signaling, interlocking, or status feedback.
Many models include practical enhancements like manual control switches for override operation during setup or emergencies.
