Overview

Medium-voltage isolating switch

RH-B Isolating Switch for Medium-Voltage Distribution Isolation

RH-B is an isolating-switch family with three-pole and single-pole configurations. The supplier tables list 11–36 kV ratings, up to 630 A for RH-B and up to 1,250 A for the GW three-pole variant, plus 15–36 kV single-pole options.

Rated voltage: 11–36 kV
Rated current: 630 / 1250 A
Short-circuit withstand: 12.5–20 kA
Impulse withstand: 95–195 kV

The RH-B source page does not publish a standard edition; confirm the applicable standard, test documents and project acceptance scope before ordering.

Confirm system voltage, earthing arrangement, installation altitude, pollution level and required operating duty with the project engineer before final selection.

Selection checklist

Prepare the Isolating-Switch RFQ

Define the system voltage. State nominal system voltage, rated voltage and insulation-coordination values.
Match continuous and short-time duty. Confirm rated current, short-circuit withstand current, peak withstand current and duration.
Choose the arrangement. Identify single-pole or three-pole construction, operating mechanism and rod length where applicable.
Specify installation hardware. Confirm mounting bracket, terminal clamp, line connection, operating eye and crossarm arrangement.
List documents and quantity. Include standard edition, drawings, test evidence, packing quantity, destination and required delivery schedule for quotation.

Configuration and supply boundary

Review the RH-B Configuration

The target source lists selectable hardware and material options. State each option explicitly so the quotation reflects the intended field installation.

Electrical coordination

Confirm rated voltage, current, impulse withstand, power-frequency withstand and leakage distance against the project study.

Operating hardware

Depending on the model, specify operating mechanism, arcing-distinguishing chamber, operating rod length, loadbuster hook or self-locking mechanism.

Materials and corrosion protection

The source lists silver-plated copper terminals and blades, porcelain or polymer insulators and hot-galvanized steel bases. Confirm the selected combination.

Commercial boundary

Quantity, packaging, delivery schedule, private label and project documents remain subject to technical review and quotation.

Frequently asked questions

RH-B Isolating Switch FAQ

Which voltage and current values are published?

The target table lists 11–36 kV rated-voltage options and 630 / 1250 A rated-current options. Confirm the exact configuration in the quotation.

What withstand values should be checked?

Review impulse withstand, power-frequency withstand, short-circuit withstand current and peak withstand current together with the insulation-coordination study.

Can the operating hardware be customized?

The source lists selectable mechanisms, brackets, terminals and, for some models, operating-rod length. Availability depends on technical review.

What should be included in a quote request?

State model, poles, voltage, current, withstand duty, operating hardware, mounting arrangement, quantity, destination market and required documents.
