The CRBS series of compact, single- or double-pole relay bases features a logical wiring version and has a relay lever release mechanism. Available with optional plug-in status and protection modules, the DIN and chassis mounting bases are rated at 12A at 300 vac and accept most popular relay designs. Logical wiring versions allow quick and easy connection of wiring in the terminals. With UL and CSA approval, the IP20 bases are molded from UL 94V-1 rated self-extinguishing glass-filled PA6. Quick installation is accomplished with the 2 mm x 2.5 mm rising clamp terminal system. Protection modules come with diode protection from reverse polarity, varistors for overvoltage and surge protection and RCs for spike suppression. All modules have a signaling option.
