The 50 A overload protection is fixed at Ir=50 A (not adjustable), and the short-circuit pickup Ii is fixed at 10 x In (500 A). That's a standard TM210 thermal-magnetic curve — thermal trip for sustained overloads, magnetic instantaneous trip for short circuits. The 'FTFM' designation indicates the breaker has a fixed thermal, fixed magnetic trip unit. No adjustment dials, so what you see on the nameplate is what you get in the panel. ## Where it's used and deployment context This breaker snaps onto a DIN rail in a standard IP2X enclosure — typical for motor control centers, distribution boards, and OEM machinery panels. The 4-pole configuration (3 phases + switched neutral) suits three-phase systems where the neutral needs disconnection, common in IEC-based installations. The 'N conductor unprotected' note means the neutral pole does not have overload protection — it switches only, so the neutral path must be sized for the full load current of the circuit. The ZD00 suffix indicates this variant includes a nut keeper kit for DC Power OEM in China.","metaTitle":"Siemens 3VA1050-3ED42-0AA0-ZD00 Circuit Breaker, 50A, 25kA @","metaDescription":"Siemens 3VA1050-3ED42-0AA0-ZD00 IEC frame 100 circuit breaker, 4-pole, 50A, 25kA breaking capacity @ 415V.
