Circuit breakers are essential in keeping electrical systems safe and reliable. The TS-709-15H is an advanced circuit breaker designed specifically for applications in circuit protection and power distribution. It is used in a wide range of applications, including residential and commercial electrical distribution systems, industrial control, and alternative energy sources. This circuit breaker has outstanding protection performance, reliable switching, and a wide range of breaking and making capacity.

Application Field

The TS-709-15H circuit breaker is used primarily as a switching device for protecting the entire system from damage due to overheating, short circuits, overloads, and ground faults. It is designed for use in single-phase 240V, two-phase 208V and three-phase 600V AC systems. The TS-709-15H is UL-listed and CSA certified with a current rating of 15A for general-purpose use. It is also capable of carrying up to 30A of inrush current, which makes it ideal for use with energy-saving HVAC systems, outdoor lighting systems, and other energy-intensive appliances/devices.

The TS-709-15H is suitable for use in hazardous locations due to its UL-listed Class I, Division 2 rating. This breaker also has excellent immunity to surge and EMI, making it great for use with sensitive electronic equipment. Additionally, this circuit breaker has a fast response time, allowing for quick protection.

Working Principle

The TS-709-15H circuit breaker has two main components: A thermal-magnetic trip unit and an arc suppressor. The trip unit is designed to detect a fault current and trip the circuit breaker. It uses a combination of temperature sensing and magnetic trip action to protect the system from temperature rise, short circuits, and ground faults. It trips in three stages: 1) A low-level trip to detect a small ground fault or minor overload, 2) A higher-level trip to detect a larger ground fault or major overload, and 3) An extra-high-level trip to detect a very large fault or extreme overload.

The arc suppressor is designed to reduce the arc that is created when the circuit breaker trips. As the breaker triggers an arc, the arc suppressor quickly activates and breaks the current, preventing the arc from reigniting and thus ensuring the safety of the circuit.

Overall, the TS-709-15H circuit breaker is a reliable and robust solution for protecting vital components in a variety of applications. It has excellent protection performance, reliable switching, and a wide range of breaking and making capacity, making it an ideal choice for use in a wide range of applications.
