What this MCCB delivers for the panel
The Siemens 3VA4195-4ED14-0AA0 is a 1-pole SENTRON molded-case circuit breaker rated 15 A continuous at 40 °C, with a TM210 thermal-magnetic release providing LI protection (long-time and instantaneous). Interrupting capacity hits 65 kA at 120 VAC, 25 kA at 277 VAC, and 14 kA at 347 VAC — enough headroom for most commercial and light industrial service-entrance or distribution panels where high fault current is a given. The 25.4 mm width (1 inch) per pole means this breaker fits standard Siemens panelboard and loadcenter mounting slots without adapters.
Thermal derating and release settings
Rated current holds at 15 A through 45 °C ambient, then steps down to 14 A from 50 °C to 60 °C, and 13 A at 65 °C to 70 °C. The TM210 release has an adjustable long-time pickup (lg) set at 15 A and a fixed instantaneous trip (li) at 300 A. Maximum power loss is 3.3 W, which keeps heat rise manageable in a densely populated panel.
Physical fit and environment
Dimensions are 75.1 mm deep, 25.4 mm wide, 129.4 mm tall (3 x 1 x 5.1 inches). Front-face protection is IP40, suitable for enclosed panel mounting where no water ingress is expected. Operating temperature range is -25 °C to 70 °C; storage from -40 °C to 80 °C. No ground-fault monitoring or communication function is built in — this is a straight thermal-magnetic breaker for basic overcurrent protection.
