Breaking capacity is where this breaker earns its keep in high-fault installations: 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and still 11.9 kA at 690 V. That covers most industrial distribution panels fed by transformers in the 1–2 MVA range. Dimensions: 130 mm height, 101.6 mm width, 70 mm depth. ## What the TM210 release means for selectivity The TM210 is a fixed thermal-magnetic release — thermal element for overload, magnetic for short-circuit. No adjustable trip settings, no communication module (this variant has no communication function). That keeps it simple and reliable for line protection where you don't need remote monitoring or adjustable curves.","metaTitle":"Siemens 3VA1112-3GD46-0AA0 SENTRON MCCB, 125 A, 4-Pole, TM21","metaDescription":"Siemens SENTRON 3VA1112-3GD46-0AA0 molded case circuit breaker, 125 A rated current, 4-pole, TM210 release.

The difference is the release: the -3GD46-0AA0 carries a TM210 thermal-magnetic release, while the -5EE32-0AA0 uses an electronic trip unit. If the panel was wired for an electronic trip (auxiliary power, communication wiring), the TM210 variant won't use those connections, but the breaker will physically fit and function as line protection."},{"question":"What are the key ratings for 3VA1112-3GD46-0AA0?","answer":"Rated continuous current Iu = 125 A at 40 °C (derates to 114 A at 70 °C).
