ABB 15 W Bell Transformer 230 V Primary 12 V AC Secondary DIN Rail Mount TM Series 2CSM228735R0802 TM15/12

ABB 2CSM228735R0802 TM15/12 is a 15 W bell transformer designed for DIN rail mounting, providing a primary voltage of 230 V and a secondary output of 12 V AC. Its compact and lightweight design (85 mm length, 35 mm width, 65 mm depth, weighing 300 g) makes it suitable for installation in both residential and commercial electrical systems.

This fail safe bell transformer ensures safe voltage stepping and offers SELV (Safety Extra-Low Voltage) protection by providing galvanic separation between the primary and secondary circuits. This protects users and connected devices from electrical shock hazards.

The transformer is equipped with sealed screw terminals that facilitate quick and reliable wiring without requiring specialized tools. Its IP20-rated housing provides touch protection and prevents the ingress of solid objects larger than 12 mm, enhancing operational safety.

Operating reliably within a temperature range of 10°C to 40°C and a frequency range of 50 Hz to 60 Hz, this transformer is optimized for consistent performance in diverse environments. Its modular design conforms to the TM series, making it easy to integrate into existing DIN rail systems.

Common applications include residential buildings, hotels, restaurants, hospitals, and medical centers where doorbells, buzzers, and other low voltage AC-powered devices are used. With its precise voltage output and durable construction, this transformer helps to extend the lifespan of connected equipment and reduce power wastage.
