Product details

The Siemens SENTRON 3VA1080-4ED36-0KH0 is a 3-pole molded case circuit breaker (MCCB) rated for 80 A continuous at 40 °C, with a line protection design — meaning it's built for feeder and main distribution duty, not motor-starting curves. The interrupting ratings climb to 121 kA at 240 V and 75.6 kA at 415 V, which gives you solid fault-clearing headroom for high-available-fault panels.

Mounts on a standard DIN rail — the 76.2 mm width (3 in) and 70 mm depth (2.76 in) fit a compact enclosure footprint. The supplied basic switch is 3VA10804ED360AA0; the auxiliary switch block carries 2 auxiliary switches plus 1 trip alarm switch (HQ), and the shunt trip (STL) is pre-installed.

Ambient operating range is -25 °C to 70 °C; storage range is -40 °C to 80 °C. The current rating holds steady at 80 A up to 50 °C, then derates linearly to 74 A at 70 °C — useful data for a hot panel or a summer peak load.

Frequently asked questions

What are the key interrupting ratings for 3VA1080-4ED36-0KH0?

At 240 V it interrupts 121 kA; at 415 V it interrupts 75.6 kA; at 440 V it interrupts 52.5 kA; at 500 V and 690 V it interrupts 11.9 kA. The continuous current rating is 80 A at 40 °C.

Where can I buy 3VA1080-4ED36-0KH0 and how is it quoted?

This part is sourced to order through independent distribution channels. Submit an RFQ for current pricing and availability — quotes are confirmed at the time of request.

Will 3VA1080-4ED36-0KH0 drop into a panel specified for 3VA1110-5ED36-0AC0?

The 3VA1080-4ED36-0KH0 is a different frame rating (80 A vs the 3VA1110's higher rating) and different auxiliary configuration. Physical dimensions and DIN-rail footprint are similar across the 3VA family, but verify the interrupting requirements and auxiliary wiring before substitution.
