Since 2002, TOMZN has established itself as a leading manufacturer of high-quality electrical protection and control devices, specializing in new energy applications. The TOMZN relay lineup delivers robust solutions for voltage monitoring, current protection, timing control, and switching needs. Designed for easy DIN-rail installation, these relays ensure safety, automation, and efficiency in residential, commercial, and industrial setups. With adjustable parameters, real-time displays, and durable construction, TOMZN relays meet the demands of today’s dynamic electrical environments.
Essential Role of Relays in Electrical Protection
Electrical systems face risks from voltage fluctuations, overcurrents, phase imbalances, and timing mismatches. Voltage monitoring relays, over/under voltage protectors, and time relays prevent damage to appliances, motors, pumps, lighting, and HVAC equipment. TOMZN relays offer precise detection and automatic response, reducing downtime and extending equipment life. Many models include digital displays for voltage, current, power, and energy monitoring, plus features like automatic recovery after faults.
TOMZN Relay Product Range: Versatile and High-Performance
TOMZN’s relay category covers essential protection and control types:
- Over and Under Voltage Protection Relays These DIN-rail mounted devices safeguard single-phase and three-phase systems. Models like the TOVPD series provide adjustable over-voltage (e.g., 230-300V), under-voltage thresholds, and automatic reconnect after stabilization. Popular options include 40A, 63A, and 100A ratings for 230V single-phase or 380V three-phase applications. Advanced versions add overcurrent protection, phase sequence monitoring, asymmetry detection, and LED indicators for status.
- Adjustable Overcurrent and Current Limit Monitors The TOMZN Din Rail 230V 1-63A Adjustable Overcurrent Protective Device offers flexible current limiting (1-63A). It protects against overloads with real-time monitoring and automatic disconnection, ideal for motors, heaters, and high-load circuits.
- Electromagnetic Relays Compact general-purpose relays like the MY2P, HH52P, and MY2NJ series feature DPDT contacts, LED indicators, and socket bases. Available in AC 110V/220V and DC 12V/24V coils, they suit control panels, automation, and switching tasks requiring reliable on/off operation.
- Programmable Time Switches and Timer Relays Weekly 7-day programmable digital timers allow scheduling for lights, pumps, fans, and appliances. Models support AC 220V/230V or low-voltage DC 12V/24V/48V, with 16A capacity, 1NO/1NC contacts, and options for 2-wire or 5-terminal setups. These energy-saving timers simplify automation in smart homes and commercial facilities.
- Three-Phase Monitoring Relays Specialized protectors handle 3P+N configurations with phase selection, adjustable voltage/current limits, and fault detection (asymmetry, sequence, loss). Rated up to 100A, they ensure balanced operation in industrial and heavy-duty applications.
Many TOMZN relays integrate smart features in related lines (e.g., WiFi-enabled models via TUYA/SmartLife for remote control, though core relay series focus on standalone reliability).
