10-30A Safety Breaker TD50B - Reliable Circuit Protection

Technical Data

Product Overview

The advanced safety circuit breaker delivers reliable overcurrent and short-circuit protection for modern low-voltage electrical networks. By integrating thermal and magnetic tripping mechanisms into a unified protection system, it ensures both delayed response under overload conditions and rapid disconnection during severe fault events. This dual-protection approach significantly enhances equipment safety and power supply continuity across diverse installations, making it an essential component for upgraded electrical infrastructures in residential, commercial, and industrial settings.

Core Functions

Accurate Overcurrent Management: In case of sustained overcurrent, the thermally-activated bimetallic strip responds progressively, disconnecting the circuit to prevent cable degradation and potential fire hazards.

High-Speed Short-Circuit Response: The integrated magnetic trip unit activates instantaneously upon severe overcurrent, clearing hazardous faults within milliseconds to protect downstream equipment.

Secure Switching and Status Indication: Equipped with quick-make/quick-break mechanisms and clear ON/OFF indicators, providing operational safety and immediate state recognition.

Modular and Scalable Design: Available in 1- to 4-pole versions with standardized rail mounting, enabling flexible integration into various distribution architectures.

Main Application Fields

Residential Complexes: Branch circuit protection in apartment distribution boards, safety control for home appliance circuits.

Retail and Hospitality: Electrical safety systems for hotels and supermarkets, protection for ventilation and refrigeration equipment.

Manufacturing Facilities: Motor circuit protection, machinery power distribution panels in industrial plants

Municipal Infrastructure: Electrical safety in metro stations and libraries, circuit protection for public lighting systems.

Renewable Energy Systems: Distribution box protection in solar power installations, circuit control for EV charging infrastructure.
