Compact circuit breaker LS TS630N ATU 500A 3P

Compact circuit breaker LS TS630N ATU – reliable protection for installations

Compact circuit breaker LS TS630N ATU is a protective device used in a wide range of electrical installations. Designed to protect against overloads and short circuits, it ensures the safety of devices and distribution networks. This model, with a rated current of 500A and a 3-pole design, is an ideal solution for both professionals and end-users looking for reliable protection.

Characteristics and application

TS630N series circuit breakers are characterized by high quality workmanship and wide configuration possibilities. Equipped with adjustable thermal-magnetic trip units (ATU), they allow for precise adjustment of protection parameters to the specifics of the load. The ATU trip unit allows current adjustment in the range of 400-500A, allowing for optimal adaptation to the characteristics of the protected circuit. This ensures that the circuit breaker reacts quickly to sudden changes in current, minimizing the risk of damage and downtime.

TS630N ATU 500A 3P circuit breaker is intended for use in:

• Distribution boards
• Main switchboards
• Protecting circuits powering devices with high power consumption
• Industrial and commercial installations
• Energy distribution systems

Parameters and possibilities

LS TS630N ATU circuit breaker offers a number of features that make it a versatile and effective solution:

• Rated current: 500A at 40°C – ensures stable operation even under high loads.
• Number of poles: 3P – ideal for three-phase electrical installations.
• Short-circuit breaking capacity (Icu): up to 100kA at 220/240V AC and 65kA at 380/415V AC – guarantees effective disconnection of the circuit in the event of a short circuit.
• Trip unit: ATU (Adjustable-thermal, Adjustable-magnetic) – allows precise setting of thermal and short-circuit protection parameters. Thermal adjustment allows adaptation to the load characteristics, and magnetic adjustment ensures a quick response to sudden current surges.
• Rated voltage: AC 690V / DC 750V – allows use in various types of electrical installations.
• Protection degree: IP20 – provides protection against accidental contact.
• Possibility of mounting additional accessories: such as auxiliary contacts, alarm contacts or solenoid coils, which increases the functionality of the circuit breaker.

It is worth noting the possibility of use in DC (direct current) installations, however, in such a case it is recommended to choose the SOLAR version. This is important for photovoltaic systems or other applications using direct current.

LS TS630N ATU circuit breaker is a solid and reliable device that will meet the expectations of even the most demanding users. Its high quality workmanship and advanced features ensure safe and efficient operation of the electrical installation for a long time.
