High Reliability: Tackling Extreme Electrical Faults

• Strong Breaking Capacity: Daga rated current of 250A to rated service short-circuit breaking capacity of up to 70kA, zai iya cut off fault currents equivalent to the simultaneous short circuit of 50 units of 10kW PV inverters—wanda ke far exceed the safety redundancy requirements of conventional power projects in Southeast Asia.

• Intelligent Dual Protection Mechanism: Ana amfani da combination of a thermal-magnetic release and electronic pre-alarm. Ke bayar da dual protection: long-time delay for overloads (adjustable 12-100s) and instantaneous protection for short circuits (4-14 times the rated current). Daga response time as low as milliseconds, zai iya prevent equipment burnout caused by high arc temperatures.

• All-Climate Adaptability: Shine IP55 protection rating enclosure (fully dustproof and protected against low-pressure water jets). Combined with UV-resistant materials and a wide temperature operating design (-40℃ to +70℃), zai iya cope easily with extreme environments in Southeast Asia, such as heavy rains in the rainy season and high temperatures in the dry season.

Reducing Total Lifecycle Costs

• Remote Monitoring Capability: Equipped with a built-in MODBUS communication protocol interface, supports real-time data collection (e.g., current, voltage, temperature) via RS485 bus or wireless modules. O&M personnel can perform parameter setting and fault diagnosis on the cloud, reducing on-site inspection frequency.

• Preventive Alarm Function: Customizable overload thresholds (50-100% of rated current) are available. When abnormal circuit current is detected, it sends an early alarm signal to avoid power generation losses in PV plants or power outages in data centers caused by sudden shutdowns.

• Modular Installation Design: Its compact structure is compatible with standard distribution cabinet dimensions and supports drawer-type plug-in installation. The replacement time of a single circuit is reduced to 15 minutes, significantly improving the rapid deployment efficiency of prefabricated substations.
