The 4-pole design covers three-phase plus neutral, common for North American and European distribution panels where the neutral needs switching. At 70 mm deep, 101.6 mm wide, and 130 mm tall, this breaker fits standard SENTRON 3VA panel cutouts. The 4-pole width is the same as the 3-pole sibling — just longer — so panel layouts already gapped for a 3VA 3-pole will accept this one with no rework on the DIN rail or busbar positions. The 3VA1110-5ED36-0AC0 is the closest functional sibling — same 4-pole, same 100 A frame, same TM release family. The difference is in the interrupting rating curve and accessory options. If your panel was specced around the -5ED36 variant, this -3GD42 will drop into the same footprint and busbar layout without rewiring, but verify the interrupting capacity at your fault level matches: the -3GD42 carries 75.6 kA at 240 V versus the -5ED36's higher-end rating. For most 240 V distribution boards, the -3GD42 is a straight swap.","metaTitle":"Siemens 3VA1110-3GD42-0AA0 SENTRON MCCB, 100 A, 4-Pole, TM21","metaDescription":"Siemens 3VA1110-3GD42-0AA0 SENTRON 4-pole MCCB, 100 A continuous, TM210 thermal-magnetic release.
