The 63 A rating holds across 40 °C to 50 °C ambient without derating; at 70 °C it still carries 58 A. The 800 V rated insulation voltage (Ui) confirms the breaker is suitable for 480 V and 600 V class systems with margin; the 17 kA rating at 690 V extends its use into 690 V industrial networks common in mining and marine installations. The UVR drops the breaker on loss of control voltage, which is a typical requirement for safety circuits and emergency-stop chains. The breaker measures 130 mm high, 76.2 mm wide, and 70 mm deep — a 3-pole frame that fits standard Siemens 3VA1 panel cutouts and busbar systems. The 76.2 mm width is three 25.4 mm pole pitches, matching the common 25 mm modular grid for DIN-rail or direct-mount enclosures. Depth of 70 mm leaves room behind the panel for wiring and busbar connections without forcing a deeper enclosure. Maximum power dissipation is 19.8 W at rated load.","metaTitle":"Siemens 3VA1163-5EF36-0DC0 SENTRON MCCB, 63 A, 3-Pole, 187 k","metaDescription":"Siemens SENTRON 3VA1163-5EF36-0DC0 molded case circuit breaker, 63 A rated at 40 °C, 3-pole, 187 kA breaking at 240 V.
