Depth of 77 mm and installation depth of 70 mm fit standard distribution boards; the 126 mm width and 90 mm height are within the envelope of a typical 4-pole RCBO. IP20 rating applies when installed in a distribution board with connected conductors — not a standalone enclosure rating. Mounting position is unrestricted. Supply can enter from top or bottom, which simplifies panel layout. Rated insulation voltage 440 V, overvoltage category III, pollution degree 2 — suitable for fixed-installation mains circuits. Surge voltage resistance 4 kV, surge current resistance 1 kA (8/20 μs). Mechanical service life 10,000 operating cycles typical. Halogen-free and silicon-free construction.","metaTitle":"Siemens 5SU9346-7CN20 SENTRON RCBO, 20A C-Char 30mA Type A,","metaDescription":"Siemens 5SU9346-7CN20 SENTRON RCBO, 4P, 20A, C-curve, 30mA Type A, 6kA per EN 60898, 10kA per IEC 60947-2.

Both share the same 30 mA Type A residual current protection and 6 kA breaking capacity, but the B-curve trips faster on lower overcurrents, which may affect selectivity with downstream MCBs. The 5SU9346-7CN20 is a closer fit if the circuit already has C-curve breakers upstream."},{"question":"Where can I buy 5SU9346-7CN20 and how is it quoted?","answer":"Sourced to order against an RFQ through independent distribution.
