The 2-pole configuration (2P) switches both phase and neutral, with the neutral conductor switching function built in — the neutral pole opens and closes with the line pole, which is required for single-phase circuits where the neutral must be isolated during maintenance. The part occupies 2 modular width units (18 mm each) on a DIN rail, fitting standard 36 mm of panel space.
The 5SQ2270-2YA16 is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.
The 5SQ2270-2YA16 is a 2-pole (2P) miniature circuit breaker, switching both phase and neutral.
The 5SQ2270-2YA16 is rated for AC/DC voltage, with a rated AC supply voltage of 400 V at 50 Hz.
Yes — both the 5SQ2270-2YA16 (16 A) and the 5SQ2270-2YA04 (4 A) share the same 2-pole form factor, 2 MWU footprint, 55 mm depth, and DIN-rail mounting. The only difference is the rated current; if the circuit load is 16 A, the 5SQ2270-2YA16 is a direct mechanical and electrical fit.
