The NXB Series Modular Circuit Breakers are engineered to deliver superior electrical protection across diverse environments, from household wiring to heavy industrial machinery. These breakers combine cutting-edge safety features with robust performance.

Key Advantages

Comprehensive Protection: Safeguards circuits against overloads, short circuits, and provides positive isolation for maintenance.
Wide Compatibility: Accommodates currents from 1A to 125A, voltages up to 415V AC or 220V DC(NXB-125), and frequencies of 50/60Hz.
Adaptive Tripping Curves: Selectable B (3–5×In),C (5–10×In),D (10–14×In), and OV (14–20×In)curves to match load types (e.g., motors, lighting, transformers).
High Breaking Capacity: Handles short-circuit currents up to 20kA (DC) or 10kA (AC), with service ratings (Ics) of7.5kA–15kA.
Extended Durability:20,000 mechanical cycles and 4,000–10,000 electrical cycles for long-term reliability.
Extreme Environment Ready: Operates flawlessly in temperatures from-35°C to +70°C, with automatic current derating for thermal stability.
Space-Saving Design: Modular widths (18mm per pole) for efficient DIN rail mounting in panels.

Certifications & Compliance

Globally certified with CE, CB, SNI, NOM, EAC, SII, and LoA marks, the NXB Series meets stringent safety and performance criteria for worldwide deployment.
