Overview of SB-PC UEC and SB-PCR UEC contactors
Welcome to our channel, where we explain complex electrical equipment in simple terms. In this video review, we introduce the SB-PC series contactors and SB-PCR reversing contactors from UEC - reliable and efficient components widely used in automated systems such as pump control panels, automatic transfer switches (ATS), and main distribution boards.
SB-PC contactors are designed for AC-3 applications and rated for currents from 115A to 630A. They come in three sizes - frame sizes 5, 6, and 7 - with control coils available in 230V or 400V AC versions.
Reliability is a key advantage. The contact assemblies are made from silver-alloy composite, with high-quality arc chutes and mechanical durability of up to 1 million cycles. These contactors also feature built-in short-circuit and overload protection, along with an energy-efficient coil that includes a built-in auxiliary contact.
SB-PCR reversing contactors are supplied as a ready-to-use kit: two contactors, mechanical interlock, mounting rails, and connection bars. It’s a plug-and-play solution that’s practical and time-saving.
The contact system requires no special tools for maintenance - a convenient test screw and contact position indicator are built-in. You can also add auxiliary contacts, thermal relays, or time delay modules in any configuration.
