Mini Circuit Breaker

XENHO operates as a dedicated factory and supplier of high-quality Mini Circuit Breakers. Designed to meet IEC/EN 60898-1 standards, our MCBs feature B, C, and D tripping curves to suit various residential and industrial loads.

What is a Mini Circuit Breaker?

XENHO Mini Circuit Breaker (MCB), also known as a miniature circuit breaker, is a reusable air switch commonly used in distribution boxes. It safeguards electrical circuits by integrating overload (thermal trip) and short-circuit (magnetic trip) protection. As a leading supplier, XENHO offers MCBs with currents from 6A to 63A and breaking capacities of 4.5kA, 6kA, and 10kA for both AC and DC applications. Our China-based factory utilizes automated production lines to ensure each unit meets international safety standards.

Tripping Curves and Application Areas

The XENHO Mini Circuit Breaker is available in three standard tripping curves to match different load types:

B Curve (3-5 In): Fastest tripping. Suitable for electronic devices and circuits with minimal inrush current.

C Curve (5-10 In): Average characteristics. Ideal for residential and commercial applications with moderate inrush loads, such as lighting and general outlets.

D Curve (10-20 In): Handles high inrush currents. Designed for industrial areas with motors, transformers, and welding equipment.

Customer Repurchase Rate

Our repurchase rate among international clients exceeds 90%; the remaining 10% consists solely of customers who have recently made their initial purchase and have not yet placed a repeat order. If we calculate the repurchase rate specifically for customers who have been with us for over a year, the figure rises to over 98%.

Customization & Manufacturing Process

We offer personalized customization services tailored to specific client requirements, covering parameters such as current ratings, breaking capacities, wiring configurations, and external markings.

Our manufacturing process utilizes fully automated assembly lines and precision testing equipment to ensure that every Mini Circuit Breaker complies with the international standard IEC/EN 60898-1.

Core components—such as electromagnetic coils and bimetallic strips—are imported from Germany and Japan; by combining these premium materials with the advantages of localized manufacturing, we achieve a perfect balance between high performance and cost optimization.

Prior to shipment, all products undergo rigorous dielectric strength testing, temperature rise testing, and operational life cycle testing to guarantee long-term, stable performance.
