Siemens 3VA2116-5HL32-0CC0 — 160 A SENTRON MCCB for Line Protection
The Siemens 3VA2116-5HL32-0CC0 is a SENTRON molded case circuit breaker (MCCB) rated for 160 A continuous current across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling. Three poles, line-protection design, with an undervoltage release (UVR) and two auxiliary switches HQ built in. Breaking capacity runs 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V, so it handles high-fault commercial and industrial service entrances where the available short-circuit current is substantial.
What the Ratings Mean for Fit
The 160 A continuous rating is flat from 40 °C through 70 °C — no thermal derating curve to calculate for standard panel ambient. That simplifies BOM sizing: the breaker carries its full nameplate current even in a warm enclosure. The 3-pole line-protection design means it's configured for ungrounded or corner-grounded delta systems, not for solidly-grounded wye with a separate neutral pole. The undervoltage release (UVR) trips the breaker when control voltage drops below a threshold — common for emergency-stop chains or undervoltage protection on motor feeders. Two auxiliary switches HQ provide status feedback to a PLC or annunciator panel.
Breaking Capacity by Voltage — One Breaker, Multiple Fault Levels
This MCCB carries a single interrupting rating that varies by system voltage: 187 kA at 240 V AC, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V. The 187 kA at 240 V is typical for a high-capacity service entrance or large transformer secondary where fault current is extreme. At 690 V the 3.7 kA rating is lower — verify the available fault current at that voltage before specifying. The breaker's physical footprint is 181 mm high, 105 mm wide, 86 mm deep — standard for a 160 A frame in the SENTRON 3VA2 family.
