The 100 A continuous rating at 800 V insulation voltage (Ui) and 690 V AC / 600 V DC operational voltage (Ue) means this switch disconnector handles full-load motor branch circuits up to that current class. The 2 kA limited short-time withstand (1 s and 0.5 s) tells you it's designed to ride through downstream faults without welding contacts — but it must be backed by an upstream protective device that clears faults above that level. The 4-pole configuration with busbar connection on front terminals suits it for main incoming or distribution panels where a neutral pole is switched alongside the three phases. ## Deployment context The front terminal arrangement for busbar connection means it's designed for horizontal or vertical busbar systems in distribution boards, not for cable entry from the rear. The IP40 front protection is suitable for indoor panel installation where no washdown or dust ingress is expected.","metaTitle":"Siemens 3VA1110-1AA42-0BH0 SENTRON Switch Disconnector, 100","metaDescription":"Siemens SENTRON 3VA1110-1AA42-0BH0 switch disconnector, 100 A rated continuous current, 4-pole, with undervoltage release and auxiliary contacts.
