Product details

SENTRON 3VA2116-0KQ42-0AA0 — 160 A MCCB with ETU860 Electronic Trip

Its ETU860 electronic trip unit provides adjustable overload protection from 240 A up to 1 600 A, with a fixed full-scale value of 160 A — meaning the trip curve is set for the breaker's frame, not the load.

Trip Unit and Protection Configuration

The ETU860 electronic trip unit supports ground-fault monitoring via summation current formation on the L + N conductor — a common requirement for TN-S or TT systems where you need residual current detection without a separate RCD. The N-conductor protection is adjustable from OFF to 20%–100% of the phase rating, giving flexibility for systems where the neutral is undersized or needs to be switched off. No undervoltage release or voltage trip is fitted as standard — those would be add-on accessories.

Thermal Performance and Environmental Range

That is unusual for a molded case breaker; most start derating above 40 °C. The maximum power loss is 19.7 W, which is moderate for a 160 A frame and manageable in a ventilated enclosure. The IP40 front protection means it is suited for indoor panel mounting, not washdown environments.

As a Siemens SENTRON product, the 3VA2116-0KQ42-0AA0 carries the usual compliance documentation for industrial MCCBs: CE marking for the European market, UL/CSA listing for North America, and RoHS/REACH declarations. Specific certificate numbers should be verified against the project's local code requirements.

Frequently asked questions

What is the breaking capacity of 3VA2116-0KQ42-0AA0 at 415 V and 690 V?

The breaking capacity is 440 kA at 415 V and 187 kA at 690 V, giving substantial fault-current headroom for industrial mains or sub-distribution.

What trip unit does this MCCB use?

It uses the ETU860 electronic trip unit with adjustable overload protection from 240 A to 1 600 A, ground-fault monitoring via summation current, and adjustable N-conductor protection (OFF, 20%–100%).

Where can I buy 3VA2116-0KQ42-0AA0 and how is it quoted?

This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm price and lead time.

Will 3VA2116-0KQ42-0AA0 drop into a panel specified around 3VA2116-5HM42-0CC0?

Both are 4-pole SENTRON 3VA frame breakers with the same 86 mm depth and 140 mm width, so the physical footprint is identical. The key difference is the trip unit — this one uses ETU860, while the other uses a different electronic trip. Verify the trip curve and protection settings match your coordination study before swapping.
