With over a decade of experience and a commitment to quality certified by internationally recognized standards, we provide solutions that power critical operations across the globe, from North America to Southeast Asia. Our FLN36-12/24 switch is engineered to offer superior performance, enhanced safety, and minimal maintenance, making it an ideal choice for modern industrial plants seeking to optimize their electrical infrastructure.
The FLN36-12/24 Indoor Load Break Switch is a cornerstone of secure and flexible power distribution. Its core function is to make, carry, and break normal load currents under specified conditions, providing a visible isolation point for maintenance and safety. Below are its key features and technical advantages:
- Advanced Arc-Quenching Technology: Utilizing SF6 gas as the insulation and arc-quenching medium, the switch ensures rapid and reliable interruption of load currents, minimizing contact wear and extending operational life.
- Robust Construction for Industrial Environments: The fully sealed, corrosion-resistant tank and high-strength operating mechanism are built to withstand the demanding conditions of industrial plants, including dust, humidity, and temperature variations.
- Enhanced Safety Design: Features include a reliable earthing switch for safe maintenance, a clear visible break indicator, and interlocking mechanisms to prevent incorrect operations, ensuring personnel safety.
- Flexible Configuration Options: Available in both fixed and withdrawable versions, the switch can be easily integrated into new or existing switchgear, Kiosk substations, or Ring Main Units (RMUs), offering great installation flexibility.
- Low Maintenance & High Reliability: The sealed-for-life SF6 gas system requires no regular topping-up, and the spring-stored energy operating mechanism ensures consistent switching performance over thousands of operations.
The benefits for your industrial plant are substantial. This switch enables safe isolation of feeders or transformers, facilitates planned maintenance without a full shutdown, and provides a reliable point for load switching, all contributing to increased uptime and operational efficiency.

Frequently Asked Questions (FAQ)
-
What is the primary application of the FLN36-12/24 Load Break Switch?
This switch is primarily used in indoor industrial plant substations for safely making, breaking, and isolating normal load currents on 11kV or 33kV feeders, transformers, or motors. It serves as a key component for sectionalizing and controlling power distribution. -
Can this switch interrupt fault (short-circuit) currents?
No, a load break switch is designed for normal load current interruption. For protection against fault currents, it must be used in conjunction with suitable protective devices like fuses or circuit breakers. -
What are the advantages of using SF6 gas in this switch?
SF6 gas provides excellent insulation and arc-quenching properties. It allows for a compact design, reduces maintenance (sealed-for-life), enables reliable arc extinction, and is non-flammable, enhancing overall safety. -
Is motorized operation available for the FLN36-12/24 switch?
Yes, motorized operating mechanisms are often available as an optional feature. This allows for remote operation and integration into automated supervisory control systems, which can be discussed based on your project requirements. -
How do I know if the switch is in the open or closed position?
The switch is equipped with a clear, direct-view position indicator (visible break) on the front, providing a reliable visual confirmation of the contact status for enhanced operational safety. -
What maintenance does this load break switch require?
Due to its sealed SF6 gas design and robust mechanism, the switch requires minimal routine maintenance. Periodic visual inspections and mechanical operation checks are typically sufficient, as specified in the user manual. -
Can this switch be used outdoors?
The FLN36-12/24 is designed as an indoor switch. For outdoor applications, it must be housed within a suitable weatherproof enclosure or cabinet to protect it from environmental elements. -
What standards does your product comply with?
Our switches are designed and tested in accordance with international standards such as IEC 62271-103 for load break switches and GB/T 11022 for common specifications of high-voltage switchgear.
