The TM240 thermal-magnetic release means the thermal pickup is fixed for a 240 A frame; the magnetic instantaneous trip point is factory-set and not field-adjustable. Interrupting capacity is the number that governs fault coordination downstream. This 4-pole unit clears 187 kA at 240 VAC, 121 kA at 415 V, 75.6 kA at 440 V, 30 kA at 500 V, and 17 kA at 690 V. Footprint is 140 mm wide, 158 mm tall, 70 mm deep — a standard 4-pole MCCB envelope for a 200 A frame. The 70 mm depth keeps the back-of-panel projection short, which matters when the gland plate or rear wiring trough is tight. Two auxiliary switches (HQ type) are built in; no undervoltage release or shunt trip is fitted on this variant, so if you need remote trip you add an external module. Power loss at rated load is 42 W — plan ventilation if the breaker is in a sealed, uncooled compartment with other heat sources.","metaTitle":"Siemens 3VA1220-5EF42-0AC0 SENTRON MCCB, 200 A, 4-Pole, TM24","metaDescription":"Siemens 3VA1220-5EF42-0AC0 SENTRON molded case circuit breaker, 200 A continuous at 40 °C, 4-pole, TM240 release, 187 kA at 240 V.
