Siemens 6SL3353-1AG41-8DA1 SINAMICS S120 1880A Power Block

Product Description

High-Power Rectification for Modular Drive Systems

The Siemens 6SL3353-1AG41-8DA1 is a heavy-duty Power Block specifically engineered for the SINAMICS S120 modular drive series. Functioning as a high-capacity 3-phase rectifier for Basic Line Modules (BLM), this assembly is responsible for converting 500V–690V AC line voltage into a stable DC link bus for downstream motor modules. Rated for a massive 1880 Amps, this power block is a critical industrial component designed for high-performance applications where non-regenerative power supply is sufficient. The unit features varnished assemblies for enhanced environmental protection and nickel-plated conductor bars to ensure maximum conductivity and resistance to oxidation in corrosive atmospheres.

Engineered for Extreme Industrial Loads

Weighing approximately 159.7 kg (352 lbs), the 6ESL3353-1AG41-8DA1 represents the robust end of the SINAMICS S120 portfolio. Unlike smaller Control Units, this is a physical power conversion assembly consisting of high-power thyristors or diodes (depending on the specific BLM configuration). It is designed to be cabinet-mounted as part of a larger Chassis-format drive lineup. The inclusion of nickel plating on the main terminals ensures low contact resistance over the equipment's long service life, even under the thermal cycling common in 50/60 Hz heavy-duty cycles.
