Medium Voltage Load Break Switch

SYHF is an excellent supplier of Circuit Breakers in China, among which the Medium Voltage Load Break Switch is based on lifetime sealed SF6 technology, providing high performance, reliability, and long life in a compact installation space. The series has recently added a new GSec designed to meet specific requirements of the latest IEC standards.

There are two forms of grounding switches: independent grounding switches and combination grounding switches with integrated current transformers. The combination current transformer forms the installation base of the grounding switch contact, thereby reducing the space required in the cabinet.

Medium Voltage Load Break Switch Product Range

IEC/ANSI indoor switches, switch fuse combinations, isolating switches, and load circuit breakers, with voltages up to 38.5 kV

Characteristics of Medium Voltage Load Break Switch

Wide working temperature range

Large number of circuit breaking operations at rated current value

Compact size for panels and CSS applications

Grounding switch with connection capability

Medium Voltage Load Break Switch is an indoor switchgear with a rated voltage of 12kV. This equipment uses SF6 as the gas arc and insulation medium, including opening, closing, and grounding three-phase, and has the advantages of small size, easy installation, and strong environmental adaptability.

The easy to install fin36-12 SF6 load switch and assembly device are made into a unique unit type (upper part of the cabinet) and installed in a stacked manner, greatly reducing the difficulty of the cabinet. Can provide a complete set of drawings for the matching cabinet

The three position switch has three positions: closing, opening, and grounding

There is an observation window on the end face for observing the status of the main contact and ground contact

Direct acting pneumatic arc extinguishing mode

Fill SF6 gas inside the sealed shell as insulation and arc extinguishing medium.

The switch has an inflation nozzle, a safety relief valve, and an SF6 gas pressure gauge.

You can choose between manual and electric operation.

It can withstand harsh environments and has passed condensation and pollution type tests

You can choose between a shunt circuit diagram or an overcurrent release (also optional)

Optional humidity switch, 1 on 1 off, 4 on 4 off

Interlocking between cabinets is optional

Main advantages of Medium Voltage Load Break Switch

Application capability with frequent switching requirements

In conjunction with current limiting fuses, it can close under high short-circuit currents

Medium Voltage Load Break Switch can work in both horizontal and vertical positions
