Rated 2 A at AC, the breaker carries 2.2 A at 30 °C ambient and derates to 1.9 A at 60 °C — that thermal curve matters if the breaker sits in a warm cabinet next to drives or transformers. Breaking capacity is 10 kA per EN 60898 and 15 kA per IEC 60947-2 at 415 V AC; the higher IEC figure gives you headroom on a 400 V industrial supply with a stiff fault current. Maximum operating voltage is 440 V AC for single- or multi-phase, and it's rated up to 72 V DC for those control-circuit applications. Sealable — that's for padlocking the toggle in the off position during lockout/tagout. Touch protection is built in, so you don't need additional finger guards on the line side. No neutral pole switching — this is a 2-pole breaker for double-pole switching of a single-phase or two-phase load, not a 1P+N configuration.","metaTitle":"Siemens Betagard 5SL4202-0RC MCB, 2-Pole, 2 A, Z-Curve","metaDescription":"Siemens Betagard 5SL4202-0RC miniature circuit breaker, 2-pole, 2 A rated, Z-characteristic, 10 kA breaking capacity per EN 60898.

It's designed for protecting semiconductor circuits, control transformers, and sensitive electronic loads where you need short-circuit protection but can't tolerate the higher trip thresholds of a C-curve."},{"question":"Where can I buy 5SL4202-0RC and how is it quoted?","answer":"This part is sourced and quoted to order against an RFQ through independent distribution.
