The TBC-4100ZM is a high-performance 4-pole miniature circuit breaker (MCB) engineered to deliver reliable protection for electrical distribution circuits against overload and short-circuit currents. With a robust 100A rated current capacity and 10kA breaking capacity, this MCB is ideal for demanding commercial, industrial, and power distribution environments where safety and reliability are paramount.
The TBC-4100ZM miniature circuit breaker represents a professional-grade solution for protecting electrical circuits in commercial and industrial installations. This 4-pole MCB combines advanced thermal-magnetic tripping technology with robust construction to ensure long-term reliability and safety.
Designed for 415V AC systems operating at 50Hz, the TBC-4100ZM provides comprehensive protection across all four poles, making it ideal for three-phase applications with neutral protection. The Type C tripping characteristic makes it particularly suitable for circuits with inductive loads, motors, and transformers where inrush currents are common.
Built to withstand demanding environments, this MCB operates reliably in temperatures ranging from -35°C to +70°C and humidity levels up to 95%. The DIN rail mounting system ensures quick installation and easy maintenance, while the compact footprint optimizes panel space utilization.
With high mechanical and electrical endurance ratings, the TBC-4100ZM is engineered for long service life in continuous operation scenarios. Full compliance with IEC 947-2 standards and CE marking guarantee that this product meets international safety and performance requirements.
Tripping Technology: The TBC-4100ZM employs thermal-magnetic tripping technology, combining a bimetallic thermal element for overload protection with an electromagnetic release for instantaneous short-circuit protection. This dual-protection mechanism ensures comprehensive circuit safety.
Type C Tripping Curve: The Type C characteristic provides tripping at 5-10 times the rated current, making it ideal for circuits with moderate inrush currents such as fluorescent lighting, small motors, and transformer circuits.
Breaking Capacity: With a 10kA breaking capacity at 415V AC, this MCB can safely interrupt fault currents up to 10,000 amperes, providing robust protection in industrial and commercial distribution systems.
Construction: The circuit breaker features a robust thermoplastic housing with silver alloy contacts for reliable switching performance. The arc chutes are designed to quickly extinguish arcs during interruption, ensuring safe operation.
Installation: Standard 35mm DIN rail mounting allows for quick installation in distribution boards and control panels. The compact 108mm width (equivalent to 6 modular spaces) optimizes panel layout efficiency.
Standards Compliance: Manufactured in accordance with IEC 947-2 (now IEC 60947-2) standards for low-voltage switchgear and controlgear. CE marking confirms conformity with European safety directives.
