That SCCR headroom matters for coordination studies: you can leave downstream breakers with lower ratings as long as the let-through energy is coordinated. The 4-pole body takes up the same width as a 3-pole unit with a neutral pole integrated, so if you're swapping in from a 3-pole spec, check the gland plate clearance on the neutral side. Power loss hits 25.5 W maximum at rated load — that's warm enough to consider lateral spacing in a densely populated panel, but within the range of a standard SENTRON MCCB. No derating needed across the full ambient range from -25 °C to 70 °C; the 160 A rating holds flat from 40 °C through 70 °C, which is useful for hot-side installations like near furnace controls or outdoor enclosures in direct sun. ## Protection and monitoring functions This breaker includes ground-fault monitoring via summation current formation on L + N conductors. It also carries a communication function and an other measurement function. No undervoltage release or voltage trigger on this variant. The trip unit is set with a full-scale value of 160 A and an initial pickup of 32 A — that suggests an electronic trip with adjustable long-time and short-time thresholds. No mechanical trip indicator on this unit, so fault events need to be read via the communication interface or local display if fitted.","metaTitle":"Siemens 3VA2116-5KQ42-0AA0 SENTRON MCCB, 160 A, 4-Pole, 187","metaDescription":"Siemens SENTRON 3VA2116-5KQ42-0AA0 molded case circuit breaker. 160 A continuous, 4-pole, 187 kA interrupting at 240 V.
