The shunt trip (STL) allows remote tripping from a safety relay or E-stop string, and the integrated 2 aux + 1 alarm switch (HQ) gives the PLC a positive status signal on open/close and trip. ## Thermal derating — what 63 A actually means at panel ambient The 63 A rating holds flat from 40 °C to 50 °C, then drops to 60.48 A at 55 °C, 59.22 A at 60 °C, 57.96 A at 65 °C, and 56.7 A at 70 °C. If your panel ambient runs 55 °C — common in a sealed NEMA 12 enclosure with a transformer nearby — you lose about 2.5 A. At 70 °C, you're down to 56.7 A, a 10 % reduction. Mount it with 70 mm depth clearance on the DIN rail; the 76.2 mm width (roughly 3 inches) fits standard 3-pole MCCB panel cutouts.","metaTitle":"Siemens 3VA1163-5EF36-0HH0 SENTRON MCCB, 63 A, 187 kA at 240","metaDescription":"Siemens SENTRON 3VA1163-5EF36-0HH0 molded case circuit breaker, 63 A, 3-pole, line protection, 187 kA at 240 V.
