Product details

The 3VA1125-3EE46-0AA0 is a 4-pole molded case circuit breaker from the Siemens SENTRON 3VA series, designed for line protection. It carries a continuous current rating of 25 A at ambient temperatures up to 50 °C, derating to 23 A at 70 °C — the full thermal curve is documented in the spec table.

Interrupting capacity by system voltage

Interrupting capacity varies with system voltage: 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 11.9 kA at both 500 V and 690 V.

Dimensions are 130 mm height, 101.6 mm width, 70 mm depth — a standard 4-pole MCCB footprint for DIN-rail or screw-mount panel installation. Rated insulation voltage is 800 V, and maximum power loss at rated current is 8.5 W, which should be factored into enclosure thermal calculations.

Frequently asked questions

What is the interrupting capacity of this MCCB at 240 V?

The interrupting capacity is 75.6 kA at 240 V, derating to 52.5 kA at 415 V and 11.9 kA at 690 V.

What trip unit does the 3VA1125-3EE46-0AA0 use?

It uses a TM220 thermal-magnetic fixed trip unit, providing overload and short-circuit protection without electronic adjustment or communication functions.
