Its interrupting capacity reaches 187 kA at 240 V and 121 kA at 415 V, giving it headroom for high-fault installations where selectivity with downstream breakers matters. The 800 V rated insulation voltage suits it for 480 V and 600 V class systems as well. ## Current rating and thermal performance across temperature range The breaker holds its full 63 A rating from 40 °C through 70 °C ambient without derating, which simplifies panel design in warm enclosures or near other heat sources. Maximum power loss is 5.4 W, a figure that matters when calculating ventilation requirements in a sealed cabinet. ## Interrupting capacity by voltage level Interrupting capacity varies with system voltage: 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3 kA at 690 V. For standard 480 V or 600 V class panels, the 75.6 kA at 500 V provides ample margin for most transformer-fed services. Dimensions are 105 mm wide, 181 mm tall, and 86 mm deep — a standard SENTRON 3VA frame that fits existing Siemens panel layouts and busbar systems.","metaTitle":"Siemens 3VA2063-5HL36-0AB0 SENTRON MCCB, 63 A, 3-Pole, 187 k","metaDescription":"Siemens SENTRON 3VA2063-5HL36-0AB0 molded case circuit breaker, 63 A continuous, 3-pole, 187 kA at 240 V.
