Siemens 3VA2 IEC frame 630, breaking capacity class C, Icu=110 kA @ 415 V, 3-pole, motor protection ETU860M, LSIG, In=500 A, overload Ir=200...500 A, short-circuit Isd=1.2...15 x In, ground-fault Ig=0.2...1 x In, UVR 24 V DC, aux switches HQ.
The Siemens 3VA2450-7MQ32-0BL0 is a 3-pole IEC frame 630 circuit breaker with a class C breaking capacity of 110 kA at 415 V, built around the ETU860M LSIG trip unit for motor protection. Rated In = 500 A, the overload protection (Ir) is adjustable from 200 A to 500 A, short-circuit protection (Isd) from 1.2 to 15 times In, and ground-fault protection (Ig) from 0.2 to 1 times In with a time delay tg of 0.05 to 0.8 s.
It has a class C breaking capacity Icu = 110 kA at 415 V, 3-pole.
It uses the ETU860M LSIG (Long-time, Short-time, Instantaneous, Ground-fault) electronic trip unit for motor protection.
It comes with a nut keeper kit, an undervoltage release (UVR) 24 V DC, 2 auxiliary switches HQ, 1 trip alarm switch HQ, and 1 electrical alarm switch.
