Product details

SENTRON 3VA1110-4EF32-0AA0 — 100 A MCCB, Line Protection

The Siemens SENTRON 3VA1110-4EF32-0AA0 is a 3-pole molded case circuit breaker (MCCB) designed for line protection, carrying a 100 A rating at 40 °C and a TM240 thermal-magnetic release. Its interrupting capacity hits 121 kA at 240 V and 75.6 kA at 415 V, giving solid SCCR headroom for most industrial distribution panels. The front face is IP40 rated — fine for enclosed panel mounting, not for washdown environments.

Rated 100 A continuously at 40 °C, the breaker holds that same 100 A at 45 °C and 50 °C. Above that, it derates: 98 A at 55 °C, 96 A at 60 °C, 94 A at 65 °C, and 91 A at 70 °C.

Interrupting capacity varies by system voltage: 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at both 500 V and 690 V.

Three-pole construction with no undervoltage release or communication module — it is a straight line-protection MCCB, no auxiliary gimmicks.

Frequently asked questions

What is the interrupting capacity of 3VA1110-4EF32-0AA0 at 415 V?

75.6 kA at 415 V. At 240 V it reaches 121 kA, and at 690 V it is 11.9 kA.

What is the thermal derating curve for this MCCB?

Rated 100 A at 40 °C through 50 °C. At 55 °C it derates to 98 A, at 60 °C to 96 A, at 65 °C to 94 A, and at 70 °C to 91 A.
