IULZXK1-1-61-20.0-G1 is a single-pole hydraulic magnetic circuit protector designed for reliable circuit protection and power switching in international applications. This unit features a 20.0 ampere rated current with a 50/60 Hz short delay (61) characteristic, providing fast response to overload conditions while tolerating inrush pulses of approximately 10 times rated current. The device is equipped with screw terminals and includes mounting provisions with 2X 6-32 threads at 0.140 inches deep, with overall dimensions of 2.490 inches width and 1.940 inches height. The protector operates with an AC impedance of 0.006 ohms at 50/60 Hz and delivers precise trip-time control across a range of current levels, from no-trip at 100% rated current to rapid response at higher overload percentages. This circuit protector is ideal for equipment requiring accurate circuit control, reliable protection against overcurrent faults, and compliance with international standards in power distribution and control systems.
