32A Miniature Circuit Breaker

PUGAO (Plannter Electric) 32A Miniature Circuit Breaker as the core protection equipment in the field of low-voltage electrical appliances, it can not only effectively prevent equipment damage and fire accidents caused by overload, short-circuit and other faults, but also realize the isolation and control of the circuit to protect the safety of personnel and equipment.

Technical Specifications

Modular Design: The width of an MCB is typically 18mm (one modular unit), designed for compatibility with standard 35mm DIN rail mounting.

Tripping Curve: The most commonly used is the Type C curve, suitable for general residential and commercial applications, capable of withstanding surge currents of 5 to 10 times the rated current.

Breaking Capacity: High-quality products manufactured by PUGAO feature a short-circuit breaking capacity of 6kA.

Function

Circuit protection: As the professional China manufacturer and supplier, our products are not only high quality but also durable. The 32A Miniature Circuit Breaker can monitor the current changes in the circuit in real time for 24 hours, and will quickly cut off the circuit once it detects abnormal conditions such as overload or short circuit, preventing equipment damage and fire and other safety accidents.

Isolation function: The product has passed ISO 9001 international quality management system certification. When the staff is repairing or checking the circuit, this MCB can disconnect the circuit to ensure the safety of the operator and avoid the risk of electric shock.

Selective protection: PUGAO factory has specialized in manufacturing low-voltage electrical equipment for 14 years. The power system is very complex. When the Miniature Circuit Breaker is cooperated with other protection equipment, it will be very intelligent to cut off only the faulty part.

For Which Applications Do We Recommend Selecting a 32A Miniature Circuit Breaker?

Key Selection: Type B, Type C, or Type D?

While "32A" merely indicates the current rating, the trip curve type is equally critical when selecting a circuit breaker. Based on your specific project requirements, PUGAO can develop a comprehensive solution tailored to your needs; alternatively, you may refer to our general recommendations below.

● C32: Most Common — General Purpose

Characteristics: Capable of withstanding instantaneous current surges of 5 to 10 times the rated current.

Applications: Residential and commercial power distribution, such as circuits for air conditioners, water heaters, and general-purpose outlets.

PUGAO Recommendation: This is our best-selling and highest-volume model, suitable for 90% of residential applications.

● D32: Industrial Type — Power-Oriented

Characteristics: Capable of withstanding current surges of 10 to 20 times the rated current; features a highly delayed response.

Applications: Industrial equipment, such as electric motors, transformers, and large-scale water pumps.

Caution: The use of D32 breakers in standard residential lighting circuits is strictly prohibited; failure to observe this warning may result in the breaker failing to trip during a short circuit, thereby creating a fire hazard.

● B32: Sensitive Type — Specialized Use

Characteristics: Trips at 3 to 5 times the rated current; features a highly sensitive response.

Applications: Precision equipment or circuits involving long cable runs, such as server rooms and purely resistive heating systems.

FAQ

1. Are you a trading company or a manufacturer?

2. What is a 32A Miniature Circuit Breaker?

A 32A Miniature Circuit Breaker is an automatic protection switching device designed for three-phase AC circuits. It consists of three independent poles, which are connected to the L1, L2 and L3 lines of the three-phase power supply. It can automatically cut off the entire three-phase circuit when overcurrent, short circuit or ground fault is detected, and protects the safety of equipments and circuits in the industrial, commercial and civil fields. Widely used in the protection of three-phase loads such as motors, transformers, distribution cabinets, air-conditioning systems, pumps, production line equipment and so on.
