Product Overview
An AC Circuit Breaker automatically disconnects the circuit during overloads, short circuits, or earth leakage faults, safeguarding electrical equipment and preventing hazards like electrical fires. The main components include the contact system, arc extinguishing system, operating mechanism, and tripping device.
Main products in this category:
-
AC MCCB : Modular design for overload and short-circuit protection.
-
AC ELCB : Detects leakage currents to prevent electrical shock.
-
AC ACB : High-capacity circuit breaker suitable for large industrial circuits.
Customer Concerns
1. What protection does an AC Circuit Breaker provide?
Customers often ask whether the breaker can safeguard sensitive equipment. AC Circuit Breakers handle overloads, short circuits, and sometimes earth leakage. AC MCCB and AC ACB are designed to protect inductive loads, such as motors and fans, while maintaining stable circuit performance.
2. How easy is it to install and maintain?
Ease of installation is a key concern. Our AC ELCB and AC MCCB feature compact, modular designs with clip-on mounting and clear labeling, making installation and maintenance straightforward even in complex electrical systems.
3. Are certifications and quality standards met?
Buyers frequently ask about safety and compliance. Zhejiang Dongan Electrical Co., Ltd’s AC Circuit Breakers are certified with CE, CB, TUV, and CCC. The factory also holds ISO9001, ISO14001, and ISO45001 certifications and operates a ROHS2.0 test lab to meet international standards.
