The 5SL4613-6: The B-curve trips between 3 and 5 times rated current (39–65 A), which is the standard choice for resistive and general-purpose loads in residential and light commercial panels. The 4-pole (3P+N) design switches the neutral as well as the three phases, which is required in some regional wiring codes (e.g., UK, Australia) for final subcircuits.
Accepts solid or stranded conductors from 0.75 mm² up to 25 mm² — covers the full range for a 13 A circuit (typically 1.5–4 mm² final subcircuit, but the larger terminal capacity also handles incoming tails or busbar feed-through). Terminal torque specified at 2.5 to 3 N·m.
