Siemens 5SJ6502-7 SENTRON MCB — 2 A, C-Curve, 1P+N, 6 kA
At 2 A and 240 V AC single-phase, this breaker protects a branch circuit drawing about 480 VA — think a small pump, a control transformer, or a lighting string. The 1P+N (switched phase plus switched neutral) design means it disconnects both conductors on a fault, which is required in some regional wiring codes for final circuits. Ambient temperature range is -20 to +45 °C, with periodic excursions to +55 °C and 95% humidity — fine for a ventilated panel indoors but not for a sealed enclosure in direct sun.
Panel integration
Snap-on DIN-rail mount, 2 width units (roughly 36 mm). Mounting position is any — horizontal, vertical, or flat — so it fits tight enclosures where orientation is constrained. Touch protection is built into the terminals; no additional finger-safe shrouds needed for standard panel access.
