MICRO GF1-10TVD-100 10A DC Circuit Breaker with Thermal-Magnetic Protection

Product Description

The MICRO GF1-10TVD-100 is a compact, high-reliability 10-ampere DC circuit breaker engineered for low-voltage DC power distribution systems, featuring thermal-magnetic trip protection for overcurrent and short-circuit fault mitigation. Designed for industrial, commercial, and renewable energy applications (e.g., solar PV systems, battery energy storage, DC motor control), this single-pole breaker operates at 125 VDC (nominal) with a breaking capacity of 10 kA, ensuring safe interruption of fault currents in DC circuits. Its compact DIN rail-mountable design, pluggable terminals, and visual trip indicator make it ideal for space-constrained electrical panels, complying with UL 489, IEC 60947-2, and RoHS standards for global industrial compliance.

Key Functions

The GF1-10TVD-100 DC circuit breaker delivers robust overcurrent protection for low-voltage DC systems. Key functions include: Thermal-magnetic trip mechanism (thermal for overload protection, magnetic for short-circuit protection); 10A rated current (adjustable trip range 8-10A) with instantaneous short-circuit tripping at 100A (10x rated current); 125 VDC nominal voltage rating (max 150 VDC) for compatibility with common DC power systems; 10 kA breaking capacity to safely interrupt fault currents; visual red trip indicator for quick fault identification; manual reset with lockable toggle switch for safety; compact DIN rail (35 mm) mounting for easy panel integration; and reverse polarity protection to prevent incorrect wiring damage. The breaker also features silver alloy contacts for low contact resistance and long service life.

Application Scenarios

The MICRO GF1-10TVD-100 DC circuit breaker is deployed in low-voltage DC power systems across industrial, commercial, and renewable energy sectors. In solar PV installations, it protects string inverters, combiner boxes, and battery chargers from overcurrent and short-circuit faults. For battery energy storage systems (BESS), it safeguards lithium-ion battery packs and DC distribution buses in residential/commercial energy storage setups. In industrial facilities, it protects DC motor controllers, conveyor systems, and automated machinery DC power circuits. The breaker is also suitable for telecommunications (data center DC power distribution), marine (boat/yacht DC electrical systems), and electric vehicle charging stations—all scenarios requiring compact, reliable DC overcurrent protection in space-constrained environments.
