It is configured as a line protection device — meaning it is intended for cable and busbar protection in distribution panels, not motor branch circuits where adjustable overloads are needed. Breaking capacity is the headline decision point here: 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at both 500 V and 690 V. Thermal derating is published: the breaker holds 50 A from 40 °C through 50 °C, then drops to 49 A at 55 °C, 48 A at 60 °C, 46 A at 65 °C, and 45 A at 70 °C. The 3-pole width of 76.2 mm (3 inches) is the standard MCCB footprint for this current class. No IP rating on the sides or rear; the breaker relies on the enclosure for overall panel seal. If you need remote trip indication or shunt trip, you add the accessory later; the 3VA platform supports plug-in auxiliaries. ## Delta: How It Sits Against a Sibling Compared to the 3VA1110-5MH36-0AA0 — which is also a 3-pole SENTRON but with an electronic release (ETU) and higher current rating — the 3VA1050-4ED36-0AA0 uses a fixed TM210 thermal-magnetic release. The TM210 is simpler, cheaper, and non-adjustable; the ETU version offers adjustable I²t curves and ground-fault options.","metaTitle":"Siemens 3VA1050-4ED36-0AA0 SENTRON MCCB, 50 A, 3-Pole, 121 k","metaDescription":"Siemens SENTRON 3VA1050-4ED36-0AA0 molded case circuit breaker, 50 A rated, 3-pole, TM210 release.
