Product details

The Siemens SENTRON 3VA1112-5EF36-0AB0 is a 3-pole molded case circuit breaker (MCCB) rated for 125 A continuous current at 40 °C, with a TM240 thermal-magnetic trip unit. It delivers a 187 kA interrupting capacity at 240 V AC, dropping to 121 kA at 415 V and 75.6 kA at 440 V — numbers that matter when coordinating with upstream gear in a high-fault panel. The 125 A frame stays flat across the 40–50 °C band (125 A at 50 °C), then derates to 114 A at 70 °C, so it handles warm enclosure environments without oversizing.

Line protection design

The TM240 thermal-magnetic release handles overload and short-circuit. Power loss is 28.1 W maximum at rated current.

Installation and compliance

Mounts on a DIN rail or panel-mount baseplate with 76.2 mm width (3 in) and 130 mm height (5.12 in). Depth is 70 mm (2.76 in), which matters when the enclosure door clearance is tight.

Frequently asked questions

What are the interrupting ratings for 3VA1112-5EF36-0AB0?

187 kA at 240 V AC, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 500 V and 690 V.

Where can I buy 3VA1112-5EF36-0AB0?

Sourced and quoted to order against an RFQ through our independent distribution network; availability and current pricing confirmed at quote time.

Will 3VA1112-5EF36-0AB0 drop into a panel specified around 3VA1112-5EE32-0AA0?

Both are 3-pole SENTRON MCCBs with the same frame dimensions (76.2 mm width, 130 mm height, 70 mm depth). The 3VA1112-5EF36-0AB0 carries a higher continuous rating (125 A vs lower) and a different TM240 release — verify the trip curve and interrupting requirements against the existing coordination study before swapping.
