TKMA3Y1200 Three pole Molded Case Circuit Breaker

Description

TKMA3Y1200 is a three pole molded case circuit breaker designed to handle currents up to 1200 amperes and operate within a voltage range of 240/480/600 VAC and 250 VDC. It is a key component of electrical distribution panels, switchgear, and motor control centers.

TKMA3Y1200

The core of this circuit breaker is the use of a thermal magnetic trip mechanism. Thermal components are sensitive to continuous overload. When the current flowing through the circuit breaker exceeds the rated value and lasts for a period of time, the heat generated by the current will cause the bimetallic plates inside the circuit breaker to bend. As the bimetallic strip bends, it will eventually trigger the contacts of the circuit breaker to open, thereby interrupting the current. This mechanism can prevent damage to connected devices caused by overheating due to continuous overload.

And magnetic components are responsible for quickly responding to short circuit situations. When a short circuit occurs, there will be extremely high current surges. The magnetic field generated by this high current is sufficient to instantly attract the firing pin inside the circuit breaker, which in turn triggers the contact to disconnect, cutting off the power supply within milliseconds. This fast response magnetic protection is crucial in preventing serious damage caused by rapid escalation of short-circuit current.

TKMA3Y1200

Main features and advantages:
Enhanced device protection: The precise overload and short circuit protection function of TKMA3Y1200 significantly reduces the risk of damage to connected electrical equipment. For example, in data centers, it can protect servers, network equipment, and cooling systems from electrical failures. This not only extends the service life of the equipment, but also reduces the need for expensive replacement and maintenance.
Ensure power continuity: By quickly cutting off faulty circuits, circuit breakers help maintain the overall stability of the power distribution system. In manufacturing plants, this means that even if a specific area malfunctions, other parts of the production line can continue to operate. This reduces unexpected downtime, improves production efficiency, and ultimately enhances the profitability of the enterprise.
Ensuring safety: Preventing electrical failures is not only related to equipment protection, but also to personnel safety. TKMA3Y1200 helps prevent electrical accidents such as electric shock and fire in environments where workers come into close contact with electrical systems, such as industrial sites or construction sites. Its ability to quickly cut off power in the event of a malfunction is a critical safety feature.

TKMA3Y1200

Application areas:
Industrial applications: In manufacturing plants, TKMA3Y1200 can be used to protect large mechanical equipment such as conveyors, industrial motors, and robotic arms. For example, in textile factories, it can protect the motors that drive spinning and weaving machines. In chemical plants, it can protect pumps, compressors, and other high-power equipment from electrical faults.
Commercial buildings: Circuit breakers can be installed on the main distribution panel in shopping centers, office buildings, and hotels. It protects the lighting system, HVAC units, and elevators from electrical abnormalities.
