The 2 A continuous rating (flat across 40 °C to 70 °C, no derate needed) and the TM110M thermal-magnetic release are sized for small motor loads or control transformers where the branch circuit needs coordinated short-circuit protection without nuisance tripping on inrush. ## Interrupting capacity — the real number The headline figure is 187 kA at 240 V — that's the short-circuit current this breaker can safely clear at the lowest common industrial voltage. At 415 V it still holds 121 kA, dropping to 75.6 kA at 440 V and settling at 7.5 kA for both 500 V and 690 V. For a 2 A frame, those are high-endurance numbers; the breaker isn't the weak link in a high-fault panel. The 800 V rated insulation voltage confirms it's built for 690 V systems without creepage concerns. ## Physical fit and panel integration Three-pole, 70 mm deep, 76.2 mm wide, 130 mm tall. That's a compact MCCB footprint — fits standard DIN-rail or screw-mount panel layouts. IP40 on the front means it's protected against tools and wires >1 mm but not sealed against dust ingress; keep it inside a rated enclosure for washdown areas. No trip indicator, no undervoltage release, no ground-fault monitoring — this is a bare-bones starter protector, not a multifunction breaker.","metaTitle":"Siemens 3VA1102-5MG32-0AA0 SENTRON MCCB, 2A, 187kA at 240V","metaDescription":"Siemens 3VA1102-5MG32-0AA0 SENTRON molded case circuit breaker, starter protection design, 2A rated, 187kA interrupting at 240V. 3-pole, TM110M release.
