Tightening torque is 2.5 to 3.5 N·m (22 to 31 lbf·in). Both top and bottom terminals are combined (line and load can share the same terminal type), which simplifies busbar or daisy-chain wiring in a panel. Plan for clearance in front of the DIN rail to allow the breaker to swing open.
Yes, both share the same 36 mm width, 70 mm installation depth, terminal range (0.75 to 35 mm²), and quick-assembly DIN-rail mount. The swap requires no DIN-rail or wiring rework, only a check that the downstream cable and load are rated for the 2 A (versus 32 A) rating.
