Product details

Key ratings and what they mean for fit

The 3VA1180-4EF36-0AE0 is a Siemens SENTRON molded case circuit breaker rated for 80 A continuous current at 40 °C through 50 °C, with a slight thermal derating to 72 A at 70 °C. The interrupting capacity reaches 121 kA at 240 V and 75.6 kA at 415 V, which means it can safely clear faults up to those levels in a panel without cascading damage upstream. The TM240 thermal-magnetic release provides fixed thermal and magnetic trip settings — no field adjustment, which simplifies specification but locks the protection curve. This 3-pole breaker is configured for line protection only — no undervoltage release, no shunt trip, no communication module, no ground-fault monitoring. The auxiliary contact block carries four HQ-rated switches for status feedback to a PLC or annunciator panel. Front IP40 protection means it's suited for dry indoor enclosures, not washdown environments.

Footprint and panel integration

The breaker measures 70 mm deep, 76.2 mm wide, and 130 mm tall — a compact 3-pole MCCB footprint that fits standard SENTRON panel layouts. Mounting is via the rear DIN rail clip or screw-mount adapter plate. The 4 auxiliary switches occupy the side slot; verify clearance for the wiring harness if the panel is densely packed.

Frequently asked questions

Where can I buy 3VA1180-4EF36-0AE0 and how do I get a price?

This part is sourced to order against an RFQ through independent distribution channels. Submit a request for quote to confirm current availability and pricing.

What is the interrupting capacity of this MCCB at different voltages?

The interrupting capacity is 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at 690 V — the rating drops significantly at higher voltages, so verify the available fault current at your system voltage.

Does this breaker include a shunt trip or undervoltage release?

No — this version ships without any auxiliary release (no shunt trip, no undervoltage release). The only add-on is the 4-switch auxiliary contact block for status signaling.
