Inquire NowDescription
A Miniature Circuit Breaker (MCB) is a crucial electrical safety device that automatically disconnects a circuit during abnormal conditions, such as overloads or faults. The UNION Miniature Circuit Breaker is engineered with precision and reliability, utilizing top-quality materials to ensure optimal performance. Its innovative design protects the arc chamber by strategically directing heat flow internally, enhancing the overall efficiency of the device.
Constructed with a PA66 non-flammable shell, the MCB ensures safety and durability. The trip units and handles are designed for easy operation, while the arc chamber is made from Q195 steel coated with zinc, offering superior protection against electrical faults. With a hardness of 24 HRC and reinforced with six aluminum rivets, the joints are robust and reliable. The two-times thicker shell coupled with heavier materials significantly enhances the device’s capability to prevent overcurrent faults and fire hazards.
