Description

Product Description

Siemens 3RV2021-4AA25 is a thermal-magnetic motor protection circuit breaker from the SIRIUS 3RV20 series designed for motor protection and manual motor starter applications. It is a 3-pole device with an adjustable thermal trip of 10 A–16 A, size S0, and DIN rail mounting with spring connections. The unit includes 1 NO + 1 NC auxiliary contacts, an ON/OFF rotary knob with lockout, and short-circuit breaking capacities and Icu/Ics ratings that vary by voltage.

  • 3-pole thermal-magnetic trip unit, adjustable 10 A–16 A; rated power data includes 4 kW (230 V), 7.5 kW (400/500 V), 11 kW (690 V); 10 HP (460 V)
  • Front-mounted auxiliary contacts 1 NO + 1 NC, ON/OFF rotary knob with handle lockout, DIN rail mount (45 mm) with spring connections
  • Short-circuit breaking capacity up to 65 kA (depending on rating); ultimate Icu up to 100 kA (240 Vac) and service Ics values by voltage
