ABB 1SNA115542R1200 DIN Rail Mounted Terminal Block

The ABB Entrelec 1SNA115542R1200 is a gray, DIN rail–mounted screw-clamp terminal block from the SNA family, designed as a 2.5 mm² triple-deck sensor terminal. With a 6 mm pitch and a 6‑position arrangement spread across three decks, it enables compact multi‑wire wiring for control‑panel sensing circuits. Rated up to 380 V AC, it accepts conductors up to 4 mm² (AWG 12), providing flexibility for medium‑signal wiring in automation installations. The device uses a secure screw‑clamp connection to ensure reliable landings in demanding panel environments and is intended for DIN rail mounting. Accessories such as separator end sections and cross-spacer jumpers are available to tailor the layout, along with end stops or jumper bars for larger channel counts. This terminal block sits within ABB’s broader DIN‑rail block lineup and is suitable for sensor and signal wiring in industrial automation, instrumentation cabinets, and machine control panels where compact, serviceable landings are required.
