Product details

The Siemens 3VA1163-5MH36-0AE0 is a 3-pole IEC frame 160 molded-case circuit breaker (MCCB) rated at 63 A continuous current, with a breaking capacity class M delivering Icu=55 kA at 415 V AC. This is a starter-protection variant (TM120M release) configured for motor branch circuits: it provides short-circuit protection with an adjustable instantaneous trip Ii=5...15 x In, but omits the overload protection element — meaning it relies on a separate overload relay upstream or downstream for thermal motor protection.

Clamp-type terminals accept copper or aluminium conductors up to the frame's rated cross-section.

Frequently asked questions

Where can I buy 3VA1163-5MH36-0AE0 and get a price?

This part is 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 price and lead time.

What does the 55 kA breaking capacity at 415 V mean for my panel?

The Icu=55 kA at 415 V means this breaker can safely interrupt a fault current up to 55,000 A without failing, which is sufficient for most industrial motor control centers and distribution panels fed by transformers up to about 2 MVA. This is the class M (medium) breaking capacity in the 3VA1 range.

Why does this breaker have no overload protection?

This is a starter-protection variant (TM120M release) designed for motor branch circuits where a separate overload relay provides the thermal protection. The breaker handles short-circuit protection only, with an adjustable instantaneous trip set between 5 and 15 times the rated current (In=63 A).
