Product details

The Siemens SENTRON 3VA1110-4EF36-0AD0 is a 3-pole molded case circuit breaker rated 100 A at 40 °C, with a TM240 thermal-magnetic release designed for line protection. At 415 V it still interrupts 75.6 kA, and at 690 V it holds 11.9 kA. This is not a motor-protective breaker — the TM240 release is a fixed thermal-magnetic curve for feeder and distribution protection.

The 3VA1110-4EF36-0AD0 measures 76.2 mm wide by 130 mm tall by 70 mm deep — a standard 3-pole MCCB footprint that fits SENTRON distribution boards and most DIN-rail-mount enclosures with the appropriate adapter. The 70 mm depth keeps it clear of gland plates and backpanel wiring troughs in 200 mm deep enclosures. Three auxiliary switches (HQ design) can be stacked on the side without increasing the width beyond the 76.2 mm frame.

Frequently asked questions

Where can I buy 3VA1110-4EF36-0AD0 and get a price?

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 commercial response.

What is the interrupting rating of 3VA1110-4EF36-0AD0 at 240 V?

121 kA at 240 V AC. At 415 V it interrupts 75.6 kA, and at 690 V it holds 11.9 kA.

What is the rated current of 3VA1110-4EF36-0AD0 at 40 °C?

100 A at 40 °C, with no derating needed up to 50 °C. At 70 °C it derates to 91 A.

Does 3VA1110-4EF36-0AD0 include a ground-fault monitoring function?

No — this is a line-protection MCCB without ground-fault monitoring. The ground-fault monitoring version is specified separately.
