UL 489 listed, mounts on 35 mm DIN rail in any position, accepts solid 2x (2.5–16 mm²) or stranded 1x (10–70 mm²). ## Panel integration M8 main contact bolts tightened with 4 mm hex socket. Humidity 10–95% non-condensing. Production lifecycle stage is current (active). RoHS compliance effective 2017-03-01. This is a dedicated UL 489 breaker; no functional cross to the listed PEP MPNs (6AG1516-3AN00-2AB0 etc.) — those are PLC CPUs, not protection devices. Auxiliary switch slot available for add-on contacts.
