What this MCCB delivers — and what the ratings mean for your panel
The Siemens SENTRON 3VA1116-5ED32-0CC0 is a 3-pole molded case circuit breaker (MCCB) rated for line protection — the primary job is protecting cables and busbars from overload and short-circuit in distribution panels. Its continuous current rating holds at 160 A from 40 °C up through 50 °C, then derates to 150 A at 70 °C, so you can size it for a 160 A feeder in a warm enclosure without oversizing. The interrupting capacity at 240 V is 187 kA — that is the fault current it can safely clear without rupturing, which matters when the available fault current at the panel is high (typical for transformer secondaries or large motor control centers). At 415 V it still clears 121 kA, and at 690 V it holds 17 kA. The rated insulation voltage is 800 V, meaning the internal clearances and creepage are designed for 690 V systems with margin.
Built-in auxiliaries and release — what you get on the frame
This MCCB ships with 2 auxiliary switches (HQ type) and an undervoltage release (UVR) factory-fitted. The UVR trips the breaker when control voltage drops below a set threshold — standard for emergency-stop circuits or undervoltage protection on motor feeders. The auxiliary switches give status feedback (open/closed/tripped) to a PLC or indicator lamp. No communication module is included, so this is a standalone breaker for hardwired panels. The frame dimensions are 130 mm height, 76.2 mm width, 70 mm depth — fits standard SENTRON 3VA mounting footprints and accepts the same busbar and terminal accessories as the rest of the 3VA1 family.
How it compares to the 3VA1110-5ED36-0AC0
The closest sibling in the SENTRON 3VA family is the 3VA1110-5ED36-0AC0. Both are 3-pole line-protection MCCBs with the same 70 mm depth and 76.2 mm width. The key difference: the 3VA1116-5ED32-0CC0 is rated 160 A continuous, while the 3VA1110-5ED36-0AC0 is rated 100 A. If your BOM calls for a 160 A feeder, the 3VA1110 will not carry the load — you need this 160 A frame. The physical mounting and busbar kits are shared, so a panel drilled for the 100 A version accepts the 160 A unit without rework.
