The TBC TLC-4100 is a high-performance 4-pole Leakage Circuit Breaker (LCB) designed for reliable protection against earth leakage, overload, and short-circuit faults in low-voltage distribution systems. It is suitable for commercial, industrial, and infrastructure applications requiring enhanced electrical safety and compliance with international standards.
The TBC TLC-4100 Leakage Circuit Breaker combines advanced earth leakage protection with thermal-magnetic overcurrent protection in a compact 4-pole configuration. Rated at 100A with a breaking capacity of 10kA, this device provides comprehensive protection for low-voltage distribution systems operating at 415V AC, 50Hz.
Engineered for demanding commercial and industrial environments, the TLC-4100 features instantaneous earth leakage detection with 300mA sensitivity and tripping time of ≤1.0 second, ensuring rapid response to ground faults. The thermal-magnetic trip unit offers reliable protection against overloads and short circuits, while the robust construction guarantees long service life with 8,000 mechanical cycles and 4,000 electrical cycles.
The DIN-rail mounting system enables quick installation in distribution boards and control panels. With an operating temperature range from -35°C to +70°C and IP20 protection rating, the TLC-4100 is suitable for diverse installation environments. Full compliance with IEC 60947-2 and CE marking ensure the product meets stringent international safety and performance standards.
Protection Technology: The TLC-4100 incorporates a Type AC network-compatible thermal-magnetic trip unit that provides coordinated protection against overload, short-circuit, and earth leakage faults. The instantaneous leakage protection mechanism responds to residual currents of 300mA within 1.0 second, minimizing risk of electric shock and fire hazards.
Breaking Performance: With a rated breaking capacity of 10kA at 415V AC, the device can safely interrupt high fault currents, making it suitable for installations with substantial supply capacity. The 4-pole configuration (3P + N) ensures all live conductors and the neutral are simultaneously disconnected during fault conditions.
Construction & Durability: The breaker housing provides IP20 ingress protection and is designed for DIN-rail mounting with compact dimensions (107mm H × 135mm W × 73mm D). The device is rated for operation in ambient temperatures from -35°C to +70°C and relative humidity up to 95%, ensuring reliable performance in challenging environmental conditions.
Standards Compliance: Manufactured in accordance with IEC 60947-2 standards for low-voltage switchgear and controlgear. CE marking confirms conformity with applicable European directives for safety and electromagnetic compatibility.
