The Siemens SENTRON 3VA2010-5HN36-0AA0 is a 3-pole molded case circuit breaker rated for 100 A continuous current at 40 °C, with the same rating holding flat through 70 °C — no derating needed across the full operating temperature band. Its ETU350 electronic overcurrent release provides adjustable trip curves for line protection duty.
Interrupting capacity and selectivity
This MCCB delivers 187 kA interrupting capacity at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3 kA at 690 V. That 187 kA at 240 V makes it suitable for high-fault service-entrance or sub-distribution boards where available fault current is high. The 800 V rated insulation voltage supports use in 480/277 V and 600 V systems with adequate margin.
Physical fit and panel integration
Dimensions: 181 mm height, 105 mm width, 86 mm depth. The 105 mm width is standard for a 3-pole frame in the SENTRON 3VA platform, so it fits existing panel cutouts and busbar spacing for that family. Front IP40 protection covers the operator interface against tool entry and small debris.
Environmental and power loss
Operates from -25 °C to 70 °C ambient; storage range -40 °C to 80 °C. Maximum power dissipation is 13.5 W at rated load — relevant for enclosure thermal budgeting, especially in sealed or high-density panels.
