The TM-4100S Residual Current Circuit Breaker is designed to provide reliable earth-leakage protection for low-voltage electrical distribution systems in commercial and industrial environments. This 4-pole RCCB continuously monitors the electrical circuit for earth-leakage currents and automatically disconnects the supply when the residual current exceeds the preset threshold of 100mA.
Featuring an electromechanical trip unit that operates independently of supply voltage, the TM-4100S ensures consistent protection even during voltage fluctuations or power supply issues. The device offers instantaneous tripping with response times of less than 0.2 seconds at rated sensitivity, providing critical protection against electric shock and reducing fire risk caused by earth faults.
Built for demanding applications, the TM-4100S combines high mechanical and electrical durability with a compact DIN-rail mountable design, making it ideal for integration into main distribution boards, commercial electrical panels, and building power distribution systems. The device operates reliably across a wide temperature range and meets international safety standards including IEC 60898-1, with certifications from TÜV, CE, and CB.
Operating Principle: The TM-4100S employs an electromechanical trip mechanism that continuously monitors the balance of current flowing through the phase and neutral conductors. When an earth-leakage current exceeding 100mA is detected, the device trips instantaneously to disconnect the circuit, preventing potential electric shock or fire hazards.
Type AC Classification: This RCCB is classified as Type AC, designed to detect alternating sinusoidal residual currents. It is suitable for general residential, commercial, and industrial applications where standard AC loads are present.
Breaking Capacity: With a rated breaking capacity of 10kA, the TM-4100S can safely interrupt fault currents up to 10,000 amperes, providing robust protection in typical low-voltage distribution networks.
Installation: The device features standard 35mm DIN-rail mounting, allowing for straightforward installation in distribution boards and electrical panels. The toggle control mechanism enables easy manual operation for testing and maintenance purposes.
Environmental Performance: Designed to operate in challenging conditions, the TM-4100S functions reliably in temperatures ranging from –35°C to +70°C and in environments with up to 95% relative humidity, making it suitable for diverse installation locations.
