The TM240 thermal-magnetic trip unit provides overload protection adjustable Ir = 560…800 A and short-circuit protection Ii = 5…10 × In. This order code also includes an integrated undervoltage release rated 24 V DC, plus a nut keeper kit for the mounting hardware. The description notes provision for up to 4 auxiliary switch blocks, making it suitable for applications needing remote status indication or interlocking. For a panel fed by a 2000 kVA transformer at 415 V, prospective fault current can reach 50–60 kA — this breaker sits at the upper end of class M, so it clears those faults without cascading upstream. The adjustable Ir (560–800 A) lets you match the breaker to the actual load cable or busway ampacity, not just the frame rating. The undervoltage release (24 V DC) drops the breaker on loss of control voltage — typical for emergency-stop circuits or undervoltage protection on motor feeders. It is factory-integrated into this order code, so no separate accessory purchase or wiring. Mounts in a standard IEC frame 1000 drawout or fixed version depending on the cradle ordered separately. Plan for minimum 100 mm clearance above and below for arc-flash containment and cable bending radius.","metaTitle":"3VA1580-5EF32-0BE0 Circuit Breaker 800A, 55kA @ 415V","metaDescription":"Siemens 3VA1580-5EF32-0BE0 circuit breaker, 3-pole, 800A, Icu=55kA @ 415V, TM240 trip unit, undervoltage release 24 V DC.
