Low voltage pole mounted circuit breaker D165T with digital trip unit

Description

These breakers are designed to operate within low - voltage networks, typically handling voltages of 600V AC or less and 750V DC or less. Their primary function is to interrupt the flow of current when faults such as overloads, short - circuits, or under - voltage conditions occur. They are widely used in various applications, including industrial plants, commercial buildings, and residential electrical systems. In industrial settings, they protect large - scale machinery and equipment from electrical malfunctions. In commercial buildings, they ensure the safety of lighting, heating, and cooling systems. In residential areas, they safeguard household appliances and wiring.

Features

• Safe Circuit Interruption：LV circuit breakers are engineered to open and close circuits safely. This is vital as improper circuit interruption can lead to electrical arcs, which may cause fires or damage to equipment. They can handle the high - energy surges associated with breaking an electrical circuit without endangering the surrounding environment.

• Repeated Breaking Operations：They are capable of performing breaking operations repeatedly. This feature ensures long - term reliability. In a power system where faults may occur occasionally, the breaker needs to be able to respond multiple times without degradation in performance. For example, in an industrial facility with fluctuating electrical loads, the breaker may need to trip and reset several times over its lifespan.

• Multiple Electrode Breaking：Many LV circuit breakers can break multiple electrodes simultaneously. In complex electrical setups, such as three - phase power systems, this ability allows for the quick and effective isolation of all live conductors during a fault. This helps in preventing the spread of electrical faults and reduces the risk of damage to connected equipment.

• High Breaking Capacity：Some models possess high breaking capacities. This is especially important in industrial and commercial applications where large short - circuit currents can occur. For instance, in a manufacturing plant with high - power machinery, a short - circuit could generate a substantial amount of current. A breaker with a high breaking capacity can safely interrupt this large current, protecting the entire electrical infrastructure.
