An integrated undervoltage release (UVR) is fitted as standard; the auxiliary release is the 3VA9608-0BB24 module. Dimensions are 248 mm high x 138 mm wide x 110 mm deep, designed for panel mounting with busbar or cable connections. ## Protection and compliance details Maximum power loss is 101.5 W; no auxiliary contacts or communication module are included on this variant.","metaTitle":"Siemens 3VA2450-5MN32-0CA0 SENTRON MCCB, 500 A, 3-Pole, ETU3","metaDescription":"Siemens SENTRON 3VA2450-5MN32-0CA0 molded case circuit breaker, 500 A rated, 3-pole, ETU350M trip unit, 187 kA at 240 V.
