By-Pass Disconnect Switch Porcelain

The By-Pass Disconnect Switch Type MSB was developed to operate in overhead distribution systems rated at 15, 27 and 38 kV grounded systems, with currents up to 630A.

Developed for transfer switching operations in distribution networks with nominal voltages up to 38 kV and nominal currents up to 630 A.

They are commonly used for the maintenance of reclosers or voltage regulators without interrupting the line.

Supplied with or without mounting support, suitable for single or double crossarms and for direct installation on metallic structures.

Basically, they are built on U-profile bases made of hot-dip galvanized carbon steel.

The insulators used are support-type insulators supplied in vitrified gray porcelain.

The blades are manufactured from high-conductivity electrolytic copper and arranged in parallel, providing much greater mechanical strength under high short-circuit currents.

The contacts are self-cleaning, high-pressure type, with stainless steel springs and safety locking devices.

The terminals are made of electrolytic copper with a tin surface treatment by electroplating, with NEMA drilling pattern or suitable for wedge-type connectors.

They feature an eye and hook for manual operation using a hot stick or for use with a load-break tool (loadbuster).

Designed in accordance with ABNT / ANSI / IEC standards.
