The thermal-magnetic TM220 trip unit provides adjustable overload protection from 28 A to 40 A and a fixed short-circuit pickup of 10 x In. It includes 100% N-conductor protection and a nut keeper kit, and is built as a DC Power OEM variant for the China market. The TM220 thermal-magnetic trip gives you a fixed magnetic pickup at 400 A (10 x 40 A), so it coordinates well with downstream branch breakers on a selective coordination study. The adjustable thermal Ir band (28–40 A) lets you dial in the exact cable or load rating without swapping the trip unit. The 100% N-conductor protection means the neutral pole is fully rated and tripped with the phase poles — required for 4-wire systems where neutral overcurrent is possible (e.g., harmonic-rich loads or shared neutrals). The nut keeper kit is a mechanical detail for panel builders: it retains the terminal nuts during wiring, saving time on assembly.","metaTitle":"Siemens 3VA1140-6GE42-0AA0-ZD00 IEC MCCB, 40A, 70kA @ 415V","metaDescription":"Siemens 3VA1140-6GE42-0AA0-ZD00 IEC frame 160 MCCB, 4-pole, 40A, 70kA breaking capacity @ 415V.
