3p 200 Amp Motorized Ac Mccb

CNKA, a Chinese factory brand, offers discounted 3p 200 amp motorized AC MCCBs. Also known as device-type circuit breakers, these units feature all components encased in a plastic housing. They typically use a modular design, including auxiliary contacts, undervoltage releases, and shunt releases. Due to their compact structure, maintenance is generally not feasible. Manual operation is standard, although larger models can be controlled electrically for opening and closing. With the prevalence of electronic overcurrent releases, these 3p 200 amp motorized AC MCCBs come in two types: Class A and Class B. Class B models provide excellent three-stage protection, but Class A models, which use thermal magnetic releases, are more common in the market due to cost considerations.

CNKA3p 200 amp motorized ac mccb Working principle

1  During an overload condition, the thermal components within the thermal release unit heat up, causing the bimetallic strip to bend and activate the free release mechanism, which then disconnects the main circuit by opening the main contact.

2  In the event of undervoltage, the armature in the undervoltage release will disengage, triggering the free release mechanism to operate and disconnect the main circuit by opening the main contact.

3  When the shunt release button is pressed, the armature in the shunt release engages, activating the free release mechanism and causing the main contact to open, thereby disconnecting the main circuit.

CNKA3p 200 amp motorized ac mccb FAQ

Q: What is an MCCB circuit breaker used for?
A: TheCNKA MCCB (Moulded Case Circuit Breaker) is an electrical safety device designed to protect circuits from overloads and short circuits caused by excessive current.

Q: Which is better, MCCB or MCB?
A: TheCNKA Miniature Circuit Breaker (MCB) is suited for low-current circuits, typically used in residential settings with minimal energy demands. In contrast, the Moulded Case Circuit Breaker (MCCB) is designed for high-current circuits, making it ideal for environments with significant energy consumption, such as large industrial applications.
