The TLC-463 is a professional-grade 4-pole leakage circuit breaker (LCB) engineered to deliver reliable protection against earth leakage, overload, and short-circuit faults in demanding commercial and industrial environments. With a rated current of 63A, breaking capacity of 10kA, and 300mA leakage sensitivity, this device ensures comprehensive electrical safety and system protection for critical power distribution applications.
The TLC-463 Leakage Circuit Breaker combines earth leakage protection with overload and short-circuit protection in a single compact device, making it an essential component for modern power distribution systems. Designed for commercial and industrial installations, this 4-pole LCB operates at 415V AC and provides instantaneous protection with a tripping time of ≤1.0 seconds.
Featuring thermal-magnetic trip unit technology, the TLC-463 offers dual-mode protection: thermal protection against sustained overloads and magnetic protection against short-circuit faults. The 300mA leakage sensitivity ensures personnel safety while minimizing nuisance tripping in industrial environments.
Built to withstand harsh operating conditions, this circuit breaker functions reliably across a wide temperature range from -35°C to +70°C and humidity levels up to 95%. The integrated TEST button allows for regular verification of the leakage protection function, ensuring ongoing safety compliance.
With compact dimensions (107mm H × 135mm W × 73mm D) and standard DIN rail mounting, the TLC-463 integrates seamlessly into existing distribution boards and control panels. Its robust construction ensures 8,000 mechanical cycles and 4,000 electrical cycles, providing long-term reliability and reduced maintenance costs.
Protection Characteristics:
The TLC-463 employs thermal-magnetic trip technology to provide comprehensive circuit protection. The thermal element responds to sustained overload conditions, while the magnetic element provides instantaneous protection against short-circuit currents up to 10kA. The residual current protection activates when earth leakage current reaches 300mA, with an operating threshold between 150mA and 300mA for optimal sensitivity.
Terminal Configuration:
The 4-pole design features clearly marked terminals (1-2 / 3-4 / 5-6 / 7-8) for straightforward wiring and maintenance. The toggle control type provides simple manual operation and clear ON/OFF indication.
Compliance & Standards:
Manufactured in accordance with IEC 60947-2 standards and bearing CE marking, the TLC-463 meets international safety and performance requirements for low-voltage switchgear and controlgear.
Installation Requirements:
Standard 35mm DIN rail mounting. IP20 protection rating suitable for installation in enclosed distribution boards and control panels. Adequate ventilation should be provided to maintain ambient temperature within specified limits.
