The SENTRON 5SM2335-6KK01 is a 3-pole residual current unit (RC unit) designed to pair with a 5SY miniature circuit breaker, forming a combined RCD/MCB assembly. The short-time delayed characteristic (selective S-type) provides coordination with downstream devices, reducing nuisance tripping on transient leakage.
Snaps onto DIN rail (REG profile) in any mounting position. Occupies 3 modular width units (each 18 mm, so 54 mm total) and conforms to DIN 43880 size 1. Depth is 70 mm, width 107 mm, height 90 mm.
Thermal derating and service life
Rated current drops with ambient temperature: 58.6 A at 40 °C, 58.59 A at 45 °C, 56.7 A at 50 °C, 54.81 A at 55 °C, 53.55 A at 60 °C, 52.29 A at 65 °C, and 50.4 A at 70 °C. Silicon-free construction, which matters for potting or conformal-coating processes that can be poisoned by silicone outgassing.
