3RV1915-1A

What is this component used for?

This component is a 3-phase busbar designed to interconnect two switches in a compact assembly. It is intended to simplify power distribution between compatible motor protection or circuit-breaker devices while maintaining an organised panel layout.

Which devices is it designed to work with?

It is designed for use with Siemens 3RV2 circuit-breakers and is intended for breaker sizes S00 and S0. When describing the item in listings or quotations, it can be identified as Siemens 3RV1915-1A.

How many switches can it connect?

This busbar is made for 2 switches. That makes it suitable for small grouped installations where two compatible devices need to be linked across a 3-phase supply arrangement.

What is the pole configuration?

It is a 3-pole component for the main current circuit. This means it is arranged for 3-phase electrical distribution across the connected devices.

What is the modular spacing?

The busbar has a modular spacing of 45 mm. This spacing is important when matching the part to the physical layout of the connected switches and the overall panel arrangement.

What type of connection does it use?

It uses fork-shape connections and is intended for screw-type terminals on the main current circuit. This combination supports straightforward integration with the specified compatible devices.

What is the rated operational current?

The rated operational current is 63 A. This rating should be checked against the requirements of the installation and the ratings of the associated devices.

What level of protection does it offer at the front?

The front protection class is IP20 according to IEC 60529. It is also described as finger-safe for vertical contact from the front, which helps make the assembly more suitable for enclosed panel applications.

Is this suitable for compact control panel assemblies?

Yes, it is well suited to compact control panel layouts where two compatible breakers need to be linked neatly and consistently. The fixed 45 mm modular spacing and 3-phase format make it useful for structured installations.

Why would this type of busbar be chosen instead of separate individual links?

A dedicated busbar can help create a tidier and more uniform assembly than separate wiring links. In the case of Siemens 3RV1915-1A, it provides a purpose-designed 3-phase connection format for two compatible switches, which can help with consistency in panel build quality.
