Here is a 330-word product introduction for DZ47S C-type 2P 40A miniature circuit breaker:
DZ47S Series Miniature Circuit Breaker
The DZ47S series miniature circuit breaker is designed to provide reliable circuit protection for residential and commercial electrical systems. This 2-pole 40A version with C-type tripping characteristic combines compact dimensions with efficient overcurrent protection capabilities, suitable for various low-voltage distribution applications.
Core Features
Employing a dual-breakpoint contact system, this device ensures rapid arc extinguishing during circuit interruption. The precision-calibrated bimetal thermal trip mechanism delivers consistent overload protection, while the electromagnetic quick-release unit provides instantaneous response to short-circuit conditions. The C-type tripping curve (5-10×In) makes it particularly suitable for circuits with moderate inrush currents, including lighting systems, socket outlets, and general-purpose power distribution panels.
Structural Advantages
Featuring a transparent polycarbonate housing with UL94-V0 flame-retardant properties, the unit maintains structural integrity under high-temperature conditions. The integrated copper alloy terminals accommodate conductor cross-sections up to 10mm², ensuring secure connections with minimal contact resistance. The ergonomic toggle lever provides clear ON/OFF indication and smooth operation, while the bidirectional mounting capability offers flexible installation options in standard DIN rail systems.
Performance Specifications
• Rated operational voltage: 240V AC 50/60Hz
• Breaking capacity: 6kA
• Mechanical endurance: ≥10,000 operations
• Electrical endurance: ≥4,000 cycles
• Operating temperature range: -25°C to +55°C
Application Scenarios
This breaker serves as primary protection for branch circuits in residential complexes, retail spaces, and light industrial facilities. Its space-efficient 2-module width (36mm) allows optimal utilization of distribution board space. The unified copper-silver alloy contacts ensure stable conductivity while resisting arc erosion, maintaining consistent performance through repeated operational cycles.
Installation & Maintenance
The product incorporates visible isolation gaps and standardized mounting hooks for simplified maintenance procedures. The scratch-resistant surface marking area permits permanent circuit identification. For optimal performance, ensure proper torque application (2.0-2.5N·m) during installation and maintain adequate ventilation clearance in panel enclosures.
