Product details

The Siemens 3VM1150-3ED26-0AA2 is a 2-pole IEC frame 160 circuit breaker from the 3VM1 series, rated for line protection with a TM210 thermal-magnetic trip unit. Overload protection is fixed at Ir = 50 A (non-adjustable), and short-circuit protection trips at Ii = 10 x In (500 A). Terminal connections are standard for panel wiring.

The TM210 trip curve gives a 10x magnetic pickup, so it rides through moderate inrush (like a group of contactors or a small transformer) but clears fast on a hard short.

Frequently asked questions

Where can I buy 3VM1150-3ED26-0AA2 and get a price?

This part is sourced to order against an RFQ through independent distribution. Current pricing and availability are confirmed at quote time — submit an RFQ for a firm commercial offer.

What does the 25 kA @ 415 V rating mean for panel coordination?

The 25 kA breaking capacity at 415 V (class N per IEC 60947-2) means the breaker can safely interrupt a fault up to that level. For panel design, verify that the available fault current at the breaker's line side does not exceed 25 kA, or you'll need a current-limiting device upstream.

What is the overload and short-circuit protection setting on this breaker?

Overload protection is fixed at Ir = 50 A (non-adjustable), and short-circuit protection trips at Ii = 10 x In, which is 500 A. The TM210 trip unit provides thermal-magnetic line protection.
