Product details

The Siemens 3VA1580-5EF32-0KH0 is a SENTRON molded case circuit breaker (MCCB) rated for line protection, with a continuous current of 800 A up to 50 °C, derating to 722 A at 70 °C.

Interrupting capacity — the real-world headroom

This breaker delivers 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 52.5 kA at 690 V. That's high-interrupting capability for systems with high fault current — think large transformer secondaries or industrial distribution close to the utility service entrance.

Auxiliary and shunt trip configuration

That means remote tripping and status feedback are built in — no field retrofit of the accessory stack. The shunt trip is wired to a remote pushbutton or safety relay; the alarm switch signals the PLC when the breaker has tripped on fault.

Frequently asked questions

What is the interrupting capacity of 3VA1580-5EF32-0KH0 at 415 V?

121 kA at 415 V, same as at 440 V. At 240 V it is 187 kA; at 500 V it is 75.6 kA; at 690 V it is 52.5 kA.

What are the physical dimensions of this MCCB?

Width 210 mm, height 320 mm, depth 120 mm. That's 8.27 x 12.6 x 4.72 inches.
