Rated operational voltage is 690 V AC, with a rated insulation voltage of 800 V, so it suits 480Y/277 V and 600 V delta systems common in North American and European industrial panels. The 4-pole design handles three-phase plus neutral switching, or can be used on three-phase loads with the fourth pole as a switched neutral. ## Thermal-magnetic trip and derating profile The TM210 trip unit is a fixed thermal-magnetic type — no interchangeable rating plugs, no electronic adjustments. Maximum power loss is 92 W at rated current — a factor for enclosure heat rise calculations when multiple breakers are ganged in a single panel. ## Interrupting ratings across common system voltages At 415 V and 440 V AC, the interrupting capacity holds at 121 kA; at 500 V it drops to 76 kA. For DC applications, the maximum rated operational voltage is 500 V DC — the manufacturer directs to the 3VA manual for specific DC switching capacity values, as the DC performance depends on the time constant and pole configuration. The 110 mm depth is the body depth; allow additional clearance for rear terminals and arc-chamber venting per the manufacturer's mounting instructions.","metaTitle":"Siemens 3VM1340-5ED42-0AA0 SENTRON MCCB, 400A, 4-Pole, 187kA","metaDescription":"Siemens 3VM1340-5ED42-0AA0 SENTRON molded case circuit breaker, 400A rated, 4-pole, TM210 trip unit, 187kA interrupting at 240V AC.
