Product details

The Siemens 3VA1112-5ED32-0AC0 is a 3-pole SENTRON molded case circuit breaker (MCCB) rated for 125 A continuous current at ambient temperatures from 40 °C up to 50 °C without derating. Above that, the thermal curve steps down: 122 A at 55 °C, 120 A at 60 °C, 117 A at 65 °C, and 114 A at 70 °C. The interrupting capacity is where this breaker earns its place in high-fault installations: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at both 500 V and 690 V. The overcurrent release is a TM210 — a thermal-magnetic trip unit with fixed settings, designed for line protection (cable and busbar protection, not motor overload). It carries 2 auxiliary switches HQ (high-qualified) for remote status indication, and the basic switch assembly is order code 3VA11125ED320AA0.

Mounting and integration — fits the standard MCCB footprint

Dimensions are 130 mm height, 76.2 mm width, 70 mm depth — the standard 3-pole SENTRON 3VA form factor.

Frequently asked questions

Will 3VA1112-5ED32-0AC0 drop into a panel specified around 3VA1112-5EE32-0AA0 without rewiring?

Both are 3-pole SENTRON MCCBs in the same 130 mm × 76.2 mm × 70 mm footprint, so mechanical fit is identical. The difference is in the overcurrent release: the -5ED32-0AC0 carries a TM210 thermal-magnetic trip, while the -5EE32-0AA0 uses a different trip curve. Check that the TM210's fixed settings match your protection coordination study before swapping — the wiring and bus connections are the same.

What compliance documentation does Siemens provide for 3VA1112-5ED32-0AC0?

Standard SENTRON series documentation includes RoHS, REACH, UL, and IEC compliance declarations. These are available from Siemens upon request or through their support portal.
