The 11.9 kA rating at 690 V is what you'd use for 600 V class systems in Canada or some mining applications. The breaker measures 76.2 mm wide (3 inches), 130 mm tall, and 70 mm deep. The depth of 70 mm means it fits flush in most enclosures without protruding past the deadfront. The trip indicator gives a visual flag when the breaker has tripped on fault, which helps a field tech identify the problem circuit without pulling the cover.","metaTitle":"Siemens 3VA1032-4ED36-0DH0 SENTRON MCCB, 32 A, 3-Pole, 121 k","metaDescription":"Siemens SENTRON 3VA1032-4ED36-0DH0 molded case circuit breaker, 32 A rated, 3-pole, 121 kA breaking capacity at 240 V.
