The Siemens 3VA1132-5EF36-0CA0 is a 3-pole IEC frame 160 circuit breaker from the 3VA1 series, rated for line protection with a TM240 thermal-magnetic trip unit. Rated at In = 32 A, the overload protection is adjustable via Ir from 22 A to 32 A, and the short-circuit pickup Ii is set at 5 to 10 times In. Clamp-type terminals simplify panel wiring.
The clamp terminals accept copper conductors up to the frame's rated cross-section, and the UVR coil draws its control voltage from a separate 120–127 V AC supply.
