SENTRON 3VA2116-7KP42-0AA0 — 160 A MCCB with ETU850, Active Production
Four poles, line protection version, fitted with the ETU850 electronic overcurrent release. The ETU850 provides adjustable long-time pickup and delay (tr min 0.5 s, tr max 20 s), short-time and instantaneous settings, plus ground-fault alarm or trip options — though this variant ships without the ground-fault monitoring module. Short-circuit breaking capacities span the voltage ladder: 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 3.8 kA at 690 V. That 242 kA at 415 V gives substantial SCCR headroom for high-fault industrial services — useful when coordinating downstream with a transformer secondary or a large motor control center.
Panel Fit and Integration
Dimensions: 181 mm height, 140 mm width, 86 mm depth. The 140 mm width is standard for a 4-pole SENTRON 3VA2 frame — drops into the same panel cutout pattern as the 3VA2216-8JP42-0AA0 without rewiring, though verify the lug kit and accessory positions if swapping between variants. IP40 on the front face — suitable for enclosed panel mounting where the breaker is behind a door. Maximum power loss of 25.5 W at rated current; factor that into the enclosure thermal budget, especially in a multi-breaker lineup. Mechanical endurance rated at 20 000 operations — typical for a 160 A frame in distribution duty. Communication function is present on this variant, enabling integration with energy management or remote monitoring systems via the SENTRON communication modules.
