SF6 gas-insulated circuit breaker LW10B

SF6spring operatedautomatic

Product name
LW10B-363 porcelain-post circuit breaker

Category
High-voltage equipment - Circuit breakers

Product overview
The LW10B-363 circuit breaker uses SF6 gas as the insulation and arc-quenching medium. Its arc chamber is a single-pressure, variable-contact-gap design. The device is intended to make and break rated and fault currents, switch lines and provide control and protection for transmission lines. The breaker is equipped with a spring-charged hydraulic operating mechanism to perform opening, closing and automatic reclosing, designed for reliable switching control.

Main features

• Insulation and arc-quenching medium: SF6 gas
• Arc chamber type: single-pressure, variable-contact-gap
• Intended use: make/break rated and fault currents; line switching for transmission line control and protection
• Operating mechanism: spring-charged hydraulic mechanism (opening, closing and automatic reclosing)
• Breaking capacity: 63 kA
• Cumulative short-circuit breaking operations: 20 cycles
• Supports selective phase switching control
• Mechanical life: 5000 operations
