Legrand 413091 Bell Transformer 230V→12V/8V 8 VA DIN-Rail

The Legrand 413091 is a 2-module DIN-rail bell ringing transformer with 230 V primary and dual 12 V / 8 V secondary outputs, rated 8 VA. It includes integrated short-circuit and thermal protection and is suitable for installation in modular distribution boards alongside other DIN-rail devices.

Features and benefits:

• Dual secondary outputs (12 V / 8 V) support both modern electronic chimes and legacy bell mechanisms from one device.
• Integrated short-circuit protection prevents damage from accidental terminal shorts during installation.
• Thermal cutout limits internal temperature rise from prolonged overload, extending transformer life.
• 2-module DIN-rail format mounts directly into the consumer unit alongside MCBs and RCDs.
• Supply busbars can pass through the device for downstream distribution without break-out.

Applications:

• Residential door-bell and chime power supply requiring SELV (12 V or 8 V) secondary.
• Light-commercial entrance signalling: shops, offices, dental and medical practices.
• DIN-rail modular consumer units where the transformer is mounted alongside MCBs and RCDs.
• Retrofit of legacy bell circuits where a self-protected DIN-rail format is preferred over plug-in transformers.
