We offer AC circuit breakers (DZ47-63, DZ47-125 series), DC circuit breakers (WTM7-63 DC MCB), DC molded case circuit breakers (WTM1-250 DC MCCB), and smart circuit breakers (WTB2-80ML WiFi/4G), covering residential, commercial, and industrial applications.
Miniature Circuit Breakers (MCB) are designed for lower current ratings up to 125A, typically used in residential and light commercial distribution. Molded Case Circuit Breakers (MCCB) handle higher currents from 100A to 630A with adjustable trip settings, suitable for industrial power distribution and main circuit protection.
Yes, our circuit breakers comply with IEC/EN 60898-1, IEC/EN 60947-2, and GB 10963 standards. Products carry CE, CB, and CCC certifications where applicable, ensuring global market acceptance and safety compliance.
Our DZ47 series MCBs offer B, C, and D curve tripping characteristics: B-curve for general lighting loads (3-5x In), C-curve for motor and inductive loads (5-10x In), and D-curve for high inrush current equipment (10-20x In).
Selection depends on rated current, number of poles (1P, 2P, 3P, 4P), breaking capacity (typically 6kA or 10kA), and tripping curve. For solar applications, DC-rated breakers are required. Consult our technical team for application-specific recommendations.
All WTAIELE circuit breakers come with a standard 12-month warranty against manufacturing defects. Extended warranty options are available for bulk and OEM orders. Contact our sales team for details.
