It is fitted with a TM210 thermal-magnetic trip unit — a fixed, non-interchangeable design that provides inverse-time overload protection and instantaneous short-circuit response. This variant is designated for line protection, meaning it is intended to protect cable and busbar feeders, not motor or generator circuits. With an interrupting capacity of 121 kA at 240 V AC and 75.6 kA at 415 V, this breaker handles high available fault currents typical in industrial switchboards and panelboard mains. The rating holds at 80 A through 50 °C, then derates to 78 A at 55 °C and 74 A at 70 °C — useful to know when the breaker is mounted in a warm enclosure alongside other heat sources. For a 3-pole breaker feeding a 3-phase load, that is 80 A per phase. The TM210 trip unit uses a bimetal element for the thermal curve and a solenoid for magnetic instantaneous pickup — the '210' designation indicates the frame size and trip technology, not an adjustable rating. Interrupting ratings drop with voltage: 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at 500 V or 690 V. This is the SCCR (short-circuit current rating) the panel designer uses for the series rating or fully-rated coordination study. Power loss is 19.2 W maximum — a figure that matters for thermal management inside a sealed enclosure. The IP40 rating on the front means protection against solid objects over 1 mm (tools, wires), but no water ingress protection; the breaker is intended for dry indoor panel mounting. The 76.2 mm width is a 3-module (3 x 25.4 mm) footprint, standard for DIN-rail mounted MCCBs in this class. The 70 mm depth means it projects less than 3 inches from the mounting surface — important when the panel door clearance is tight. This is a current-production part with no announced end-of-life. The SENTRON 3VA platform is Siemens' main MCCB family, so spares and replacements are straightforward to source. For a BOM freeze or critical-spare holding, this part is a safe choice — no last-time-buy clock ticking.","metaTitle":"Siemens 3VA1180-4ED36-0AA0 SENTRON MCCB, 80A, 3-Pole, 121kA","metaDescription":"Siemens SENTRON 3VA1180-4ED36-0AA0 molded case circuit breaker. 80A continuous, 3-pole, TM210 trip unit. 121kA interrupting at 240V.
