Product: TVPS163B Plug Base Circuit Breaker Size: 63A Power supply: 230VAC 50/60Hz Installation: 35mm DIN rail Key functions and benefits Protects connected equipment from overvoltage, undervoltage, and overcurrent by disconnecting supply when preset thresholds are exceeded. Automatic recovery restores power automatically when voltage returns to the configured recovery range, reducing the need for manual resets. Builtin voltage and current displays provide realtime monitoring for quick status checks and easier troubleshooting. Configurable thresholds and timing allow precise adaptation to different loads and operating conditions. Plug base design and DIN rail installation simplify replacement and panel mounting in distribution boards and control cabinets. Robust mechanical life rated to 100,000 operations for reliable longterm use. Technical highlights and adjustable parameters Model: TVPS163B Maximum load adjustment options: 1 to 40 A (default 40 A) or 1 to 63 A (default 63 A) Overvoltage protection threshold: adjustable from 221 V to 300 V or OFF (default 280 V) Overvoltage recovery voltage: adjustable from 220 V to 299 V (default 250 V) Overvoltage action time: adjustable 0.1 s to 10 s (default 0.1 s) Undervoltage protection threshold: adjustable from 150 V to 219 V or OFF (default 160 V) Undervoltage recovery voltage: adjustable from 151 V to 220 V (default 180 V) Undervoltage action time: adjustable 0.1 s to 10 s (default 0.1 s) Overcurrent adjustment range: 1 to 40 A (default 40 A) Overcurrent trip delay (action time): adjustable 0.1 s to 512 s (default 5.0 s) Recovery delay after trip: adjustable 2 s to 120 s (default 60 s) Poweron delay configuration: parameter range 2 s to 10 s (default 2 s) Note on initial startup: on first connection the unit requires about 10 seconds before it becomes operational. The poweron delay parameter can be configured from 1 s to 500 s (default 10 s). The device becomes active only after the red indicator goes out. Mechanical life: 100,000 operations Mounting: 35 mm DIN rail Practical applications Residential distribution panels: Protect household appliances and circuits from voltage swings and overloads while providing visible voltage and current readings. Small commercial and industrial control panels: Integrate into motor control or equipment distribution boards to provide adjustable overcurrent and voltage protection with automatic recovery. Workshop equipment and motor protection: Use for motors and tooling where configurable trip thresholds and delays help prevent nuisance trips while protecting against sustained faults. Why choose this model configurable thresholds and timing let you tailor protection to a wide range of loads and operating environments. Direct voltage and current readouts reduce the need for external meters, speeding up diagnosis and setup. Plug base and DIN rail compatibility make installation and replacement quick and compatible with standard distribution systems. Automatic recovery and adjustable delays minimize downtime and manual intervention after transient events. What to know before installation Ensure supply is 230VAC 50/60Hz. Set maximum load and protection thresholds according to the protected equipment ratings. Allow the initial poweron delay period before expecting the unit to enter normal operation; the red indicator must go out. Install on a standard 35 mm DIN rail and ensure wiring and panel layout follow relevant local electrical practice. This TVPS163B plug base circuit breaker provides flexible, adjustable protection and ondevice monitoring for distribution and control applications where overvoltage, undervoltage, and overcurrent protection are required.
