Why Photos Are Essential for a Proper Retrofit Kit

When designing a retrofit kit, precision and compatibility are key. To ensure that a new circuit breaker fits perfectly in the place of the old one, we always ask for clear photos of the panel — both with the door open and with the door closed.

Photo with the door open

• Shows the old location of the circuit breaker.

• Helps us estimate whether the new retrofit will fit mechanically and electrically.

• Provides insight into how the copper connection pieces should be designed.

Photo with the door closed

• Reveals whether there are any obstructions for the new front panel (door closure).

• Important to check if there are meters, displays, or other instruments that could interfere.

• Ensures that locks, hinges, or other door components will not block the installation.

The result

With these photos, we can assess in advance whether the retrofit kit will fit seamlessly into the existing panel. This prevents surprises on site and guarantees a solution that is safe, efficient, and fully customized.

Do the retrofit kits comply with the IEC 61439 / IEC 60947 standard?

At LV Retrofit, we believe in honesty and technical clarity.
That is why we do not use the IEC 61439 standard as a label for our retrofit kits.

The reason is simple: IEC 61439 is a panel standard.
It defines requirements for a complete low‑voltage switchgear assembly, including thermal performance, short‑circuit withstand strength, IP rating, and mechanical durability.
To comply with this standard, you would need to recreate and test every single panel individually — an almost impossible task, since every panel is unique in its design and configuration.

Our retrofit kits consist of copper connection pieces, a mounting frame, and a door front.
These components ensure that a new circuit breaker (such as Schneider, Siemens, Mitsubishi or ABB) can be placed precisely in the correct position inside an existing panel.
We make no modifications to the panel itself in order to artificially meet IEC 61439 requirements.
The panel remains as it is; our kits simply provide the safe and practical integration of the new breaker.

Transparency Over Marketing

Where others may use IEC 61439 as a marketing label, we choose transparency:

• The breaker itself complies with its product standard (IEC 60947).

• The panel falls under IEC 61439, and compliance is the responsibility of the panel builder or inspector.

• Our retrofit kits are designed for compatibility and safety, without making claims that are technically unsound.

This way, you know exactly what you are getting: a retrofit solution that is reliable, transparent, and honestly positioned.
