Key ratings and what they mean for your panel
The 3VA1116-5ED32-0CA0 is a 3-pole IEC frame 160 molded-case circuit breaker rated 55 kA Icu at 415 V AC — breaking capacity class M. That Icu figure means it can safely interrupt a fault current up to 55 kA without welding its contacts or rupturing the case, which is the spec that governs arc-flash coordination downstream. The TM210 trip unit provides fixed overload protection at 160 A (Ir = 160 A) and fixed short-circuit protection at 10 × In (Ii = 1600 A). For a 160 A feeder, this gives a clean, non-adjustable curve suited to distribution panels feeding fixed loads like lighting or small motor groups where you don't want field-adjustable settings.
Built-in undervoltage release and accessory kit
This order code ships with a nut keeper kit and an undervoltage release (UVR) rated 120–127 V AC, 50/60 Hz. The UVR trips the breaker if control voltage drops below roughly 70% of rated — standard for emergency-stop circuits or upstream interlock schemes where loss of control power must open the main feeder. The nut keeper kit secures the breaker on the DIN rail or mounting plate; no separate accessory order needed.
